Analysis and comparison with other level sensors

(1) Optical fiber level gauge
Based on optical technology. Use optical fiber as the sensor unit. Take out the sensitive state as an optical signal. Then photoelectric conversion. So it is easy to match with highly developed electronic control devices.

Compared with other conventional sensors, optical fiber sensors have high sensitivity, fast response speed, and strong resistance to electromagnetic interference. Corrosion resistance, good electrical insulation, small size and easy to form a remote monitoring network with optical fiber transmission system. Especially in the harsh environment of flammable and explosive, it is widely used.

(2) Differential pressure level gauge.Differential pressure level gauges use the principle of liquid pressure. At the bottom of the liquid, check the pressure difference between the liquid pressure and the standard atmospheric pressure. It deforms the semiconductor diffusion silicon film through the pressure of the liquid bottom.

Cause the bridge to be unbalanced. The circuit outputs a voltage corresponding to the liquid level height. In order to obtain the liquid level signal. It has the characteristics of high precision (0.7%), small drift and strong anti-overload capability.

But when the density of the medium changes with the temperature, pressure and composition of the medium, the differential pressure level gauge will produce a false level.

(3) Servo level gauge.
The servo liquid level gauge controls the float to follow the liquid level or interface changes through the servo motor. The servo float level gauge is subjected to different buoyancy forces on the liquid surface, in the liquid and on the interface through the float.

The gravity sensor is used to measure the weight of the float. It can send out long-distance signals at the same time. Use microcomputer for remote control. Its dynamic tracking error can reach 0.1mm.

At the same time, it can also compensate for the additional weight error caused by the low liquid level. The measurement accuracy of the liquid level can reach 0.7mm. The sensitivity can reach 0.1mm.

In addition, it also has self-diagnosis and communication functions. The level gauge has high reliability. But the price is relatively high.

(4) Radar level gaugeThe use of radar waves to measure the liquid level is a technology that has been paid close attention at home and abroad in recent years. It uses a horn-shaped waveguide to emit low-power microwaves (tens of microwatts).

Tank level measurement using pressure

Pressure level sensors can be used to establish levels in rivers, tanks, wells or other liquids. The pressure at the bottom of the liquid-filled container is directly related to the height of the liquid.

The transmitter measures this hydrostatic head and provides a final level. In order to obtain an accurate reading, the measuring device must be located at the lower point where you want to measure; it is usually installed or placed at the bottom of the container.

When measuring the liquid level, the specific gravity must be considered. Consider the following equation:

     H = P / SG or P = SG? H

H-the height of the measured liquid. It is usually measured in inches, centimeters, meters, feet, etc.
P-Hydrostatic head at the bottom of the tank. Usually in inches of water column, feet of water column, horizontal bar, psi, Pascal’s, etc.
SG-the proportion of the medium. The dimensionless number is calculated from: measured medium density ÷ water density at 4 ° C. For example, the density of kerosene is equal to 0.82 g / cm 3. Therefore, the kerosene of SG is 0.82g / cm 3 · 1.00g / cm 3 = 0.82.

What Is the Principle of Ultrasonic Level Measurement ?

Ultrasonic waves detect an object in the same way as Radar does it. Ultrasonic uses sound waves, and Radar uses radio waves. When the ultrasonic pulse signal is targeted towards an object, it is reflected by the object, and the echo returns to the sender.

The time traveled by the ultrasonic pulse is calculated, and the distance of the object is found.

Bats use a well-known method to measure the distance while traveling.

The ultrasonic level measurement principle is also used to find out fish positions in the ocean, locate submarines below water level, also the position of a scuba diver in the sea.

We will refer to Fig-1 and make an effort to understand the technicalities of the ultrasonic level transmitter.

An ultrasonic level transmitter is fixed at the top of a tank half filled with liquid.

The reference level for all measurements is the bottom of the tank.

The level to be detected is marked as “C”, and “B” is the distance of the ultrasonic sensor from the liquid level.

Ultrasonic pulse signals are transmitted from the transmitter, and it is reflected back to the sensor.

The travel time of the ultrasonic pulse from the sensor to the target and back is calculated.

Level “C” can be found by multiplying half of this time with the speed of sound in the air.

The measuring unit’s final result can be centimeters, feet, inches, etc.

Level = Speed of sound in air x Time delay / 2

Ultrasonic Level Measurement
TipYou can see our range of Ultrasonic Level Transmitters here.

Practical System Design Problems of Ultrasonic Level Transmitter:

The above principle of measurement looks quite straightforward and true only in theory.

In practice, there are some technical difficulties that are to be taken care of to get the correct level of reading.

  1. The velocity of sound changes due to the variation of air temperature.
    • An integrated temperature sensor is used to compensate for changes in the velocity of sound due to temperature variations.
  2. There are some interference echoes developed by the edges, welded joints, etc.
    • This is taken care of by the software of the transmitter and called interference echo suppression.
  3. Calibration of the transmitter is crucial.
    • Accuracy of measurement depends on the accuracy of the calibration.
    • The Empty distance “A” and measurement span “D” is to be ascertained correctly for inclusion in the calibration of the transmitter.
  4. The transient characteristics of the sensor will develop a Blocking distance as shown in Fig-1. Span “D” should never extend to the blocking distance.

The Basic Structure of an Ultrasonic Transducer:

structure of an Ultrasonic Transducer

An ultrasonic sensor is the heart of the ultrasonic level Transmitter instrument.

This sensor will translate electrical energy into ultrasound waves.

Piezoelectric crystals are used for this conversion process.

Piezoelectric crystals will oscillate at high frequencies when electric energy is applied to it.

The reverse is also true.

These piezoelectric crystals will generate electrical signals on receipt of ultrasound.

These sensors are capable of sending ultrasound to an object and receiving the echo developed by the object.

The echo is converted into electrical energy for onward processing by the control circuit.

Functional Block Diagram of a Typical Ultrasonic Level Transmitter:

We will refer to Fig-3 Functional Block Diagram to clarify the physical structures of an Ultrasonic Level Transmitter.

A micro-controller-based Control Circuit monitors all the activities of the ultrasonic level transmitter.

There are two Pulse Transmission Circuits, one for transmitter pulse and the other one for receiver pulse.

The pulse generated by the transmitter pulse is converted to Ultrasound pulses, by the Ultrasonic Sensor(Transmitter) and targeted towards the object.

This ultrasound pulse is reflected back as an echo pulse to the Ultrasonic Sensor (Receiver). The receiver converts this Ultrasonic pulse to an electrical signal pulse through the pulse generator.

The time elapsed, or the reflection time is measured by the counter. This elapsed time has relation to the level to be measured. This elapsed time is converted to level by the Control Circuit. There is a Timing Generator Circuit which is used to synchronize all functions, in the ultrasonic level measurement system.

The level is finally converted to a 4-20mA signal. 4mA is 0% level, and 20mA is the 100% level (see Fig-1).

This 4-20mA output signal carrying the level data can be transmitted to long distance to Process Control Instruments.

Common Applications for Ultrasonic Liquid Level Sensors

Ultrasonic liquid level sensors are used for liquid level, solid material level, the tank body, and open channel flow. Their performance is very good. Ultrasonic level sensors are also ideal for applications where continuous level measurement is required.

The most popular application of ultrasonic level sensors is to measure the level of liquid in tanks, wells, pits or lakes.If the container is linear, extrapolating the volume measurement is easy. In a non-linear container, a strapping table is usually used to adjust the reading to a certain volume as the level increases and decreases. Most of our ultrasounds are specifically designed for level measurement.Find the right sensor for you. Since ultrasonic sensors work without the need to touch the medium, they are ideal for difficult or corrosive liquids. Such as acids, wastewater, and others.

Typical Media:

  • Acids
  • Wastewater
  • Inks and Paints
  • Slurries
  • Food and Beverage
  • Semiconductor Process Chemicals
  • Oils and Petroleum Distillates

Another very popular application of ultrasonic sensors is solid level detection. The trick is actually to use a sensor with twice the required distance. This gives you a stronger signal, which in turn provides a better echo for the sensor’s measurements. You may also need to tilt the sensor mount so that it is perpendicular to the angle of repose.
Measuring solids has always been difficult. But ultrasound will still be the main condition for continuous non-contact measurement.

Open channels are the main means of transporting, filtering, and metering water. Open channel flow monitoring is used in water treatment plants, environmental monitoring, and irrigation canals. Ultrasonic sensors are an excellent choice for open channel flow.

Liquid Level Measurement with Ultrasonic Sensors

Tank level sensor

Tank level senor is a level sensor used to measure the tank level. The liquid level is the level of the liquid in a sealed container (such as a water tank) or an open container (water tank). The instrument that measures the liquid level is called a liquid level sensor, a liquid level gauge or a liquid level transmitter. The liquid level sensor is a kind of level instrument. Hydrostatic, Ultrasonic, Magnetostrictive, Radar, Differential Pressure are commonly choices for tank level measurement. Liquid level sensors have been around for decades for leak detection or level measurement. Common measured medium are: Water, Fuel, Diesel, Gasoline, diesel, liquefied gas, liquid ammonia, etc.

Ultrasonic level sensor wastewater

The ultrasonic level gauge is widely used in water level meter measurement projects in: Water plants. Wastewater treatment plants. Chemical reagent plants. Dye factories. Pulp mills and other factories. And is one of the main level measurement methods in modern intelligent automation industry. Ultrasonic technology has been used in the wastewater industry for more than 30 years for its high cost performance. Level gauges are widely used in industrial wastewater treatment plants and municipal wastewater treatment plants. Ultrasonic level gauges have the most applications, but their installation and measurement are limited by space.

In addition, since the propagation time of sound waves is affected by temperature, the ultrasonic sensor must be equipped with a temperature sensor. Ultrasonic level gauges are more accurate when used indoors or at groundwater levels.

Outdoors, the ultrasonic sensor generates heat due to sunlight. This will lead to inaccurate compensation for the propagation time of the sound waves, which will cause measurement errors. In chemical plants, there are a lot of high-concentration gases over chemical liquids, which will also change the propagation time of sound waves and even absorb sound waves. The shortest distance that an ultrasonic sensor can measure is usually 10-50cm. When installing, consider the “blind zone” that cannot be measured.

The differential pressure level gauge is a meter that calculates the liquid level (differential pressure) in a tank. By measuring the pressure difference at two different points of the container. For example, a 500 mm water column corresponds to a pressure of 500 mmH20. In many applications, however, there is additional vapor pressure above the liquid. Vapor pressure is not part of the level measurement. So impulse tubes and capillaries with seals are needed to counteract its presence.Capillary columns and sealing systems solve many installation problems with impulse tubes. These systems include an external sensing diaphragm. This diaphgram connected to a differential pressure transmitter via an oil-filled capillary column. The change in pressure causes a displacement of the diaphragm. So that the pressure is transmitted to the transmitter through the oil-filled capillary. The oil-filled capillary system is carefully welded and manufactured. So it is a reliable sealing system. This type of structure eliminates leak points and blockages that may occur in the impulse tube.

These gauges are the preferred replacement for the sight glasses. They are similar to float devices, but they communicate the liquid surface location magnetically.  The float, carrying a set of strong permanent magnets, rides in an auxiliary column (float chamber) attached to the vessel by means of two process connections.  This column confines the float laterally so that it is always close to the chamber’s side wall. As the float rides up and down the fluid level a magnetized shuttle or bar graph indication moves with it. Showing the position of the float and thereby providing the level indication.  The system can work only if the auxiliary column and chamber walls are made of non-magnetic material.    

Sino-Inst provides float designs optimized for the specific gravity of the fluid being measured. Whether butane, propane, oil, acid, water, or interfaces between two fluids, as well as a large selection of float materials. This means the gauges can handle high temperatures, high pressures and corrosives fluids. Oversized float chambers and high-buoyancy floats are available for applications where buildup is anticipated.

Chambers, flanges and process connections can be made from engineered plastics. such as Kynar or exotic alloys such as Hastelloy C-276.  Special chamber configurations can handle extreme conditions. Such as steam jacketing for liquid asphalt, oversized chambers for flashing applications, temperature designs for liquid nitrogen and refrigerants. Numerous metals and alloys ( titanium, Incoloy and Monel ) are available for varying combinations. Like high-temperature, high-pressure, low-specific-gravity and corrosive-fluid applications.  Magnetic level gauges can also be outfitted with magnetostrictive and guided-wave radar transmitters. This allow the gauge’s local indication to be converted into 4-20 mA outputs and digital communication. That can be sent to a controller or control system.

Float level gauge is mainly composed of magnetic float, sensor and transmitter. When the magnetic float ball changes with the liquid level and floats up and down along the catheter. The magnetic steel in the float ball attracts the reed switch at the corresponding position in the sensor. Which changes the total resistance (or voltage) of the sensor. The transmitter then converts the changed resistance (or voltage) signal into a 4-20mA current signal output.
The float ball level gauge uses a magnetic float ball as a measuring element. Which makes the resistance in the sensor change linearly through magnetic coupling. The smart converter converts the resistance change into a 4-20mA standard current signal. It can display the percentage of liquid level, the current of 4 ~ 20mA and the value of liquid level. Remote transmission control room can realize automatic detection, control and recording of liquid level. The instrument is suitable for the sewage treatment of petroleum, chemical, power, light industry and pharmaceutical industries. And the measurement of the medium level in various atmospheric and pressure vessels. It is especially ideal for the liquid level measurement of underground storage tanks and storage tanks.

Features of Float level transmitters:

  • Suitable for the measurement of the liquid level and interface of the liquid medium in the container. In addition to on-site instructions, it can be equipped with remote transmitters, alarm switches and complete detection functions.
  • Innovative indication, intuitive reading, eye-catching, observing the direction of the indicator can be according to user needsChange the angle.
  • Large measuring range, not limited by the height of the storage tank.
  • The indicating mechanism is completely isolated from the measured medium, with good sealing, high reliability and safe use.
  • Simple structure, easy installation, easy maintenance, corrosion resistance, no power supply required, explosion-proof. At the lower limit, the float floats upright on the water.

How Tank Level Sensors Work?

The level of the liquid medium in the container is called the liquid level. And the instrument that measures the liquid level is called the liquid level transmitter. Level transmitter is a kind of level instrument.

There are two types of level transmitters, one is continuous and the other is point-off. The continuous level transmitter is a real-time monitor of the height of the liquid in the container. The point type, which generally takes two points, high and low, and outputs an alarm signal when the medium in the container reaches these two points. The types of liquid level transmitters are very wide. Specific include magnetic flap liquid level gauge, tuning fork vibration type, differential pressure type, pressure type. Ultrasonic, magnetostrictive liquid level gauge, magnetic flap, radar, and so on.

Levels of media such as: water, viscous fluids, and fuels, or dry media such as bulk solids and powders can be measured using the transmitter.

Level measurement transmitters are used in a myriad of applications that require level measurement within containers or tanks. These transmitters often find their application in material handling, food and beverage, power, chemical, and water treatment industries.

Q&A

Fluid level sensors are termed as the sensors used for detecting liquid levels or interfaces between liquids. Such as water and oil or solids and liquids. These sensors can also be defined as transducers or as integrated systems with instrumentation and control capabilities. This type of fluid level sensor is one of the most important sensors. Fluid level sensor plays a vital role in a variety of industrial and applications.

Industrial applications include fluid-level sensing in transport tanks, storage tanks and water treatment tanks. And also in the petrochemical industries for sensing liquids. Such as petrol, diesel and other fuels. Liquid level measurement is significant in household applications. Including electronic devices. Such as, water dispensers, water evaporators, steamers.

The monitoring system of boilers, heating systems. Washing machines, steam irons, juice squeezers, automated coffee machines, etc.

Fluid Level sensors are designed for specific applications compared to general applications.

Point level sensors are devices that detect variation in liquid levels. And the levels are based on the presence or absence of liquid media at various points in a vessel or tank. Most often, the function of point level sensors is: High level or low-level alarms. Spill-prevention sensors. Pump protection alarms. Or pump control components.

In the simplest terms, point level sensors operate in either an on or off state. And point level sensors are used to control external devices that share an on/off functionality.
Examples of liquid level sensors that can work as point-level sensors:

Fuel tank level measurement can be achieved by using fuel level sensors. These Fuel level sensors work on a hydrostatic pressure principle. By installing a sensor at the base of the fuel tank can associate the pressure created by the level of fuel above the device. And this has a direct relationship to the level by a simple calculation. This calculation can be seen by using the Impress conversion software here.

The things to consider when selecting a fuel level sensor is that the materials used are compatible with the type of fuel you have so for instance on the submersible devices you must make sure that the pressure diaphragm, O ring seals, housing material and Cable sheath are all suitable for complete submersion in the fuel.

Typically we would suggest using a PTFE or FEP cable sheath but for petrol or gasoline although a specially made Hytrel cable may be necessary.

If the installation is a screw-type fitting in the base of the tank then just the housing, O ring seal, and diaphragm are of concern. Ceramic pressure sensor or stainless steel silicon pressure sensors are fine and a stainless steel housing are recommended.

Ultrasonic Sensors are good choice for Water Level Measurement.

The water and wastewater industry has many requirements for measuring the level of water. In applications such as flumes, weirs, pipes, tanks, wells, basins, and cooling towers. Ultrasonic sensors are reliable, cost-effective instruments for these applications. In operation, the sensor is mounted over the water. To determine the distance to the water, it transmits a sound pulse that reflects from the surface of the water. And measures the time it takes for the echo to return.

Sometimes structural components, such as a small pipe, are located in the acoustic path between the ultrasonic sensor and the water. They can reflect a portion of the sound and produce a false echo that interferes with the ability of the sensor to properly detect the echo from the surface of the water. Advanced ultrasonic sensors can be adjusted to ignore these false echoes, which therefore enables them to provide accurate water level measurements.

How to use a hydraulic flow meter?

  • A flow meter can be placed in any location of the hydraulic line to detect the flow rate. Flow meters with variable port sizes are available that are suitable for different hydraulic systems.
  • When the hydraulic system operates, the fluid is passed towards the flow meter.
  • A flow meter mainly contains 3 parts; the primary device, a transducer and a transmitter. The transducer senses the hydraulic fluid passing through the primary device.
  • And a usable flow signal is generated by the transmitter when the sensed signal is sent by the transducer.
  • The volume is calculated based on the principle that the volume of fluid passing is directly proportional to the cross-sectional area and the fluid velocity.
  • Also, the mass flow is directly proportional to fluid density and volume.
  • Then, this calculated hydraulic measurement is displayed on the hydraulic flow meter gauge.
  • All standard hydraulic oil flow meters supports unidirectional flow.
  • But, reverse flow by-pass options are also available with some selected flow meters.

Extended reading: Metal Tube Flow Meter-Variable Area Flow Meters Principle

Flow is the amount of fluid that passes through a pipe or device at a cross-section in a unit of time. This quantity is expressed by mass and is called mass flow. Expressed by volume, called volume flow. Expressed by weight, called weight flow.

Because the density of a fluid changes with changes in the state parameters of the fluid, the volume state must be given while specifying the state of the fluid.

Especially for gas, its density varies significantly with pressure and temperature. In order to facilitate the comparison of the volume flow rate, the volume flow rate in the working state is often converted to the volume flow rate in the standard state (temperature is 20 ° C and absolute pressure is 101325Pa).

Commonly used flow measurement methods include speed-type flow measurement methods, volumetric flow measurement methods, and direct or indirect methods to measure the mass of fluid flowing through the cross section of the pipe per unit time.

In the above method, more speed-type flow measurement method instruments are applied.

Except for the standard throttling device which does not need to be tested for the current flowmeter, almost all other flowmeters need to be calibrated when leaving the factory. During the use of the flowmeter, it should also be calibrated frequently.

The volume method is most commonly used. This is a method of measuring the volume of fluid flowing into a constant volume container within a measurement time to obtain the flow rate.

The mass method is a method of weighing the mass of a fluid flowing into a container within a measurement time to obtain a flow rate.

During calibration, a pump is used to draw the test fluid from the liquid storage container through the calibrated flowmeter and enter the liquid container.

The temperature of the fluid is measured while the weight is weighed to determine the density of the measured fluid at that temperature.

Divide the weight of the measured fluid by the density of the fluid at the measured temperature to obtain the volume of the fluid.

Comparing it with the meter’s volume indication (accumulated pulse number), the meter constant and accuracy of the calibrated flowmeter can be determined. The accuracy of this system can reach 0.1%.

The working principle of the standard volume tube method is based on the volumetric method (standard volumetric method), but it is a dynamic measurement.

The standard flowmeter comparison method is to connect the calibrated flowmeter and the standard flowmeter in series to the pipeline flowing through the test fluid, and compare the two measured values ​​to find the error. The accuracy of the standard flowmeter is 2 to 3 times higher than that of the calibrated flowmeter.

Where are flow meters used? Or, What does a flow meter measure?

At industrial sites, meters that measure fluid flow are referred to as flow meters or flow sensors.

It is one of the most important instruments in industrial measurement.

With the development of industry, the accuracy and range of flow measurement requirements are getting higher and higher.

In order to adapt to various purposes, various types of flowmeters have been successively launched,

widely used in oil and gas, petrochemical, water treatment, food and beverage.

Industries such as pharmaceuticals, energy, metallurgy, pulp and paper, and building materials.

  1. Measurement of gas mass flow in industrial pipelines
  2. Smoke flow rate measurement from the chimney
  3. Calciner flue gas flow measurement
  4. Air flow measurement during gas process
  5. Compressed air flow measurement
  6. Gas flow measurement during semiconductor chip manufacturing process

Flowmeters are devices that measure the rate of liquid, gas or vapor that passes through them.

Some flowmeters measure flow as the amount of fluid passing through the flowmeter during a time period (such as 100 liters per minute).

Other flowmeters measure the totalized amount of fluid that has passed through the flowmeter (such as 100 liters).

Flow measurement can be described by :
Q = A x v

Q is flow rate, A is the crosssectional area of the pipe, and v is the average fluid velocity in the pipe.

Putting this equation into action, the flow of a fluid traveling at an average velocity of a 1 meter per second,

through a pipe with a 1 square meter cross-sectional area is 1 cubic meter per second.

Note that Q is a volume per unit time, so Q is commonly denoted as the “volumetric” flow rate.

Now consider the following equation:
W = rho x Q

Where W is flow rate (again – read on), and rho is the fluid density.

Putting this equation into action, the flow rate will be 1 kilogram per second,

when 1 cubic meter per second of a fluid with a density of 1 kilogram per cubic meter is flowing.

(The same can be done for the commonly-used “pounds”. Without getting into details — a pound is assumed to be a mass unit.)

Note that W is a mass per unit time, so W is commonly denoted as the “mass” flow rate.

Now — which flow do you want to measure? Not sure? In some applications, measuring the volumetric flow is the thing to do.

Consider filling a tank.

Volumetric flow may be of interest to avoid overflowing a tank,

where liquids of differing densities can be added.

(Then again, a level transmitter and high level switch/shutoff may obviate the need for a flowmeter.)

Consider controlling fluid flow into a process that can only accept a limited volume per unit time.

Volumetric flow measurement would seem applicable.

In other processes, mass flow is important.

Consider chemical reactions,where it is desirable to react substances A, B and C.

Of interest is the number of molecules present (its mass), not its volume.

Similarly, when buying and selling products (custody transfer) the mass is important, not its volume.

In recent years, flow measurement technology has developed rapidly. Most of the steam flow measurement uses differential pressure flowmeters and vortex flowmeters.

In practical applications, the maximum diameter of the high temperature vortex flowmeter can only be 300mm and the maximum temperature is 450℃. Therefore, in the measurement of high temperature and high pressure large-diameter steam flow, the differential pressure flowmeter still has unique advantages. For example, Annubar flowmeter, differential pressure orifice flowmeter, etc.

Differential pressure flowmeter manufacturing technology and national and international standards are quite mature. With the introduction of the multivariable transmitter dynamic full compensation intelligent technology, the accuracy of high temperature pressure and large diameter steam flow measurement has been greatly improved, and the installation and maintenance workload has been reduced.

Fuel flowmeter refers to the flowmeter used to measure the flow rate of fuel. Commonly referred to as turbine flow meters and oval gear flow meters.

A flow meter is used to measure the quantity of fluid that has been moved during the transfer process. They have a visual display, which can be either mechanical or digital, for the user to read off the measurement. Flow meters are used within a variety of fluid transfer applications. And therefore whilst they are always used to measure the fluid, the ways in which they work are slightly different.
Of course, the fuel flow meter also has some characteristics of its own, such as:
Explosion proof
Pulse output
Unaffected by changes in fluid density, viscosity, temperature, pressure, and conductivity.

If you need more accurate measurement, you can choose a mass flow meter. Coriolis mass flowmeters have zero drift but the impact is relatively small. Higher operating costs. Mass flow meters can measure temperature and density online. Oval gears are relatively stable for mechanical flow meters.

Turbine Flow Meters are the most widely used diesel fuel flow meters. Measure your diesel fuel or oil consumption with our fuel flow meter.

Diesel Flow Meter Working Principle

The working principle of the turbine flow meter:

Fluid flows through the sensor housing.Because the blade of the impeller has a certain angle with the flow direction, the impulse of the fluid causes the blade to have a rotating moment.

Blades rotate after overcoming frictional torque and fluid resistance.After the torque is balanced, the speed is stable.Under certain conditions, the speed is directly proportional to the flow rate.

Because the blade is magnetically permeable, it is in the magnetic field of a signal detector (made of permanent magnetic steel and coils).

The rotating blade cuts the magnetic field lines and periodically changes the magnetic flux of the coil.

Thereby, an electric pulse signal is induced at both ends of the coil.This signal is amplified and shaped by the amplifier to form a continuous rectangular pulse wave with a certain amplitude.

Remotely transmitted to the display instrument, show the instantaneous flow rate and cumulative amount of the fluid.In a certain flow range, the pulse frequency f is proportional to the instantaneous flow Q of the fluid flowing through the sensor.

In addition to supplying diesel flowmeters, Sino-Inst also supplies various diesel level sensors.

A flow meter is an instrument that indicates the flow rate to be measured and/or the total amount of fluid in a selected time interval. Simply put, it is a meter used to measure the flow of fluid in a pipe or open channel.

Flowmeters are devices that measure the rate of liquid, gas or vapor that passes through them.

Some flowmeters measure flow as the amount of fluid passing through the flowmeter during a time period (such as 100 liters per minute).

Other flowmeters measure the totalized amount of fluid that has passed through the flowmeter (such as 100 liters).

Flow measurement can be described by :
Q = A x v

Q is flow rate, A is the crosssectional area of the pipe, and v is the average fluid velocity in the pipe.

Putting this equation into action, the flow of a fluid traveling at an average velocity of a 1 meter per second, through a pipe with a 1 square meter cross-sectional area is 1 cubic meter per second.

Note that Q is a volume per unit time, so Q is commonly denoted as the “volumetric” flow rate.

Now consider the following equation:
W = rho x Q

Where W is flow rate (again – read on), and rho is the fluid density.

Putting this equation into action, the flow rate will be 1 kilogram per second, when 1 cubic meter per second of a fluid with a density of 1 kilogram per cubic meter is flowing.

(The same can be done for the commonly-used “pounds”. Without getting into details — a pound is assumed to be a mass unit.)

Note that W is a mass per unit time, so W is commonly denoted as the “mass” flow rate.

Now — which flow do you want to measure? Not sure? In some applications, measuring the volumetric flow is the thing to do.

Consider filling a tank.

Volumetric flow may be of interest to avoid overflowing a tank, where liquids of differing densities can be added.

(Then again, a level transmitter and high level switch/shutoff may obviate the need for a flowmeter.)

Consider controlling fluid flow into a process that can only accept a limited volume per unit time.

Volumetric flow measurement would seem applicable.

In other processes, mass flow is important.

Consider chemical reactions,where it is desirable to react substances A, B and C.

Of interest is the number of molecules present (its mass), not its volume.

Similarly, when buying and selling products (custody transfer) the mass is important, not its volume.

Flow Meters Pulse Output

The signal output by the flowmeter is generally a pulse signal or a 4-20mA current signal. Both types of signals output instantaneous flow (also used by relays to output cumulative signals. The principle is the same, and will not be repeated).

Our purpose is to PLC Calculate and display the instantaneous flow value and calculate the cumulative value. When the input signal is a pulse signal. When calculating the instantaneous flow rate, you must follow a strict time interval to ensure the accuracy of the instantaneous flow rate.

So, when calculating the instantaneous flow rate, This must be done using timed interrupts. Moreover, only one interrupt program can be run in a PLC system. No other interrupts are allowed (even low priority interrupts are not allowed to run).

Prevents interference with the accuracy of timed intervals. Calculating the instantaneous flow rate is to convert the accumulated pulse number of this time period into the accumulated flow rate. Divided by time is the instantaneous flow.

For the 4-20mA input, the instantaneous flow rate can be directly obtained by simply converting according to its corresponding range. The cumulative flow is the cumulative flow accumulated in each time period is the cumulative flow.

Flow meters with a pulse output essentially use pulses per litre to measure the amount of fluid being dispensed. And then send a signal to an external piece of equipment to tell them this information.

A fuel pulse meter for example is often connected to a remote display or a fuel management system.

Our range of fuel pulse meters include models suitable for different fluids and are compatible with pumps with differing flow rates. Ensure that when selecting your meter, its flow range meets your pump’s flow capabilities.

Of course, in addition to measuring Diesel Fuel flow meters. Other flow meters can also output pulses or 4-20mA signals.

For example, if you need to measure the waste water flow of a 2-inch pipe, then you can refer to: Magnetic Flow Meters Guides.

Fuel Flow Meters for Diesel Engine Fuel Consumption

For generators, boats, trains to hydraulic packs applications. Diesel engines are becoming increasingly popular.

Fuel consumption and efficiency are generally not monitored in Diesel Engines. And the unit’s performance has to be gauged from the manufacturer’s test figures and often never checked again.

With increases in fuel prices, the possibility of theft from remote installations along with many other factors. So the monitoring the fuel consumption of diesel engines has become increasingly important with the transport industries in particular taking a lot more interest in their vehicles fuel consumption.

This chart approximates the fuel consumption of a diesel generator. Based on the size of the generator and the load at which the generator is operating at. Please note that this table is intended to be used as an estimate of how much fuel a generator uses during operation. And is not an exact representation due to various factors that can increase or decrease the amount of fuel consumed.

Fuel flow meter aircraft

A fuel flowmeter for plane indicates an engine’s fuel use in real time. This can be useful to the pilot for ascertaining engine performance and for flight planning calculations.

The types of fuel flow meter used on an aircraft depends primarily on the powerplant being used and the associated fuel system. Not every plane or associated system uses the same kind of flow meter to get the job done.

In most cases, many flow meters perform tasks related to maintaining a single plane. Some of the more common flow meters in use include:

  • A mass flow fuel flow indicating system used on turbine-engine aircraft uses the direct relationship between viscosity and mass to display fuel flow in pounds per hour
  • A turbine flow transducer in this fuel flow sensor produces a current pulse signal from an opto-electronic pickup with a preamplifier
  • A transducer and microprocessor for control functions are located in the base of this turbine fuel flow sensor. The gauge is menu driven with numerous display options

https://www.aircraftsystemstech.com/2017/06/fuel-system-indicators.html

Every flow meter must be properly maintained and calibrated. All flow meters become inaccurate over time through regular use. Regular re-calibrations and general standards to ensure proper operation.

Flow meters designed for the aviation industry are made of the highest quality materials and to specific industry standards. That way, everyone working in the industry and flying the skies can be in the safest environment possible at all times.

  • How much fuel is consumed onboard a ship, is directly related to the performance. The better the performance, the lower the fuel consumption during operation. In this equation, accuracy is not negligible.
  • An offset of 1% in measurement on a vessel operating 200 days a year consuming an average of 100 tons a day equals an offset of 200 tons a year. Depending on the price of HFO or MGO used, this misread has the potential to range up to USD 100,000.
  • The Coriolis Mass Flow Meters used in our Fuel Consumption System has an accuracy better than 0,2% of nominal flow directly measured in mass. Whereas most volumetric flow meters are in the range 0,5% to 2,0%. And they rely on volumetric conversion which depends on the temperature to calculate a mass flow.
  • By installing one or more mass flow meters (depending on engine supply line layout and desired insight) fuel consumption can be monitored closely in real-time.
  • The main principle is to measure the flow of fuel before and after the engine and/or generators. When you compare the consumption data with measurements of actual speed and position (based on speed log and GPS signals). You are able to directly measure the fuel efficiency.
  • If you require more detailed readings, for example, one set of meters per consumer or one set for the ship’s entire consumption. Additional flow meters can be installed.

Air flow meters types

The Carmen vortex refers to the placement of a cylindrical or triangular object in the fluid. Two rows of vortices with opposite rotation directions will be generated downstream of this object.

More about Types Of Air Flow Measurement Instruments.

An ultrasonic transmitting probe and a receiving probe are oppositely installed on both sides of the downstream pipeline of the Carmen vortex generator. Due to the influence of the Carmen vortex on the air density, the time from the transmitting probe to the receiving probe of the ultrasonic wave becomes later than that of the non-vortex and a phase difference occurs. By processing this phase signal, a vortex pulse signal can be obtained.

The working principle of the hot film type air flow meter is similar to that of the hot wire type air flow meter, and they all work with Wheatstone bridge. The difference is that the hot film type does not use platinum wire as a hot wire. But uses a thick film process to make the hot wire resistance, compensation resistance, and bridge resistance on the same ceramic substrate.

In the process of generating the Carmen vortex, the air pressure on both sides of the vortex generator will change. The pressure acts on the metal foil through the pilot hole, causing it to vibrate. When light from a light-emitting diode strikes a vibrating metal foil. The reflected light on the metal foil received by the phototransistor is vortex-modulated light. And its output is demodulated to obtain a frequency signal representing the air flow.

When no air flows, the bridge is in equilibrium. The control circuit outputs a certain heating current to the hot wire resistance RH. When there is air flowing, the heat of RH is absorbed by the air and becomes cold. Its resistance value changes. The bridge loses Balance. If the temperature difference between the hot wire resistance and the intake air is kept constant and constant, the current IH flowing through the hot wire resistance must be increased. Therefore, the hot-wire current IH is a function of the mass air flow.

The vane type air flow meter has a simple structure and high reliability. Yet, it has a large volume, large intake resistance and slow response.

Working Principle of Slurry Flow Meters

Different types and designs of flow meter are available. Choose the best one depends on the application and the type of liquid being measured. Electro-magnetic meters are typically used for slurry and corrosive liquids. Because magnetic flow meters are able to measure these substances accurately.

Keeping accurate records is essential. Because we need to know exactly how much slurry has been spread in every field, and to demonstrate full regulatory compliance.  Today’s modern slurry flow meter designs can help to achieve this.

What is the principle of magnetic flow meter? – Faraday’s Formula

Faraday’s Formula
E is proportional to V x B x D where:

E = The voltage generated in a conductor
V = The velocity of the conductor
B = The magnetic field strength
D = The length of the conductor

To apply this principle to flow measurement with a magnetic flow meter. First is to state that the fluid being measured must be electrically conductive for the Faraday principle to apply.As applied to the design of magnetic flow meters, Faraday’s Law indicates that:the signal voltage (E) is dependent on V, B, D.V is the average liquid velocity ;B is the magnetic field strength ;D is the length of the conductor ( which in this instance is the distance between the electrodes).

Why do you need a slurry flow meter?

When spreading any type of slurry or digestate, accuracy is essential. This means it is important to monitor the spreading process with a slurry flow meter. So that you can be sure of consistent application across the area which is being treated.

At the same time as ensuring that enough slurry is applied, however, it is equally vital not to use more than is needed. This is important for several reasons. One is that over-application is a waste of valuable slurry resources, meaning you spend more than is necessary. Slurry is one of the most cost-effective ways of fertilising agricultural land. But only the application carried out properly..

Spreading too much slurry can also lead to a number of pollution issues. Which could risk failing to comply with legal regulations. Especially if it involves contamination of soil or water courses.

Challenges for Slurry Flow Meter

Flow meters designed for slurries depend on several factors:

  • The flow velocity and profile. A balance of keeping solids moving, but not too fast.
  • The amount of solids in the carrier fluid.
  • The solids properties in the carrier fluid.  They vary in many qualities including shape and size.
  • Chemical composition of the fluid. Liners for corrosive fluids.
  • Solid Abrasiveness. Rough solids cause system noise that interferes with the measurement. Abrasiveness liners can be used if needed.
  • Heavy slurry noise may affect on the measurement accuracy and stability
  • Shorter replacement cycle because of the mechanical damage caused by slurry.
  • High density red-mud covered on the electrodes requires frequent maintenance for the cleaning.

Sino-Instrument’s solutions for Slurry and Solids flow

Looking for a meter to monitor slurry spreading? Sino-Instrument offers high-quality magnetic flow meters which complies with many official standards. It is known for being highly reliable and durable, needing little maintenance to keep it in good working order. The magnetic flow meter is used in the waste water industry and other sectors as well as for slurry, which is a testament to its quality.
To monitor slurry application, the magnetic flow meter can be easily installed within the pipeline, positioned either near to the pump or on the applicator. It has strong liners which are resistant to slurry, and will measure the flow rate accurately, usually in m3 per hour.
Non-retained liners (extruded liner) are susceptible to failures as a result of vacuum conditions that can be created due to a pump or valve failure. Besides, meters that have extruded liners generally have a shorter life due to the aggressiveness of the chemicals used. Sino-Instrument uses an injected molded PFA liner with a retaining grid. This retaining grid plate, used to reinforce the PFA liner, acts like rebar in concrete. This rugged construction holds the liner in place and prevents the liner from caving in due to vacuum conditions. The thickness and durability of the injection molded PFA liner provides a flow tube that is capable of handling the most severe applications.

Industrial Vortex Flow Meter

Compressed air flow meter working principle

There are a variety of measurement principles can be used to measure compresses gas.

Turbine gas meters are robust meters, used to measure gas consumption. In gas distribution, transmission, industrial plants and for commercial users. The meter tracks the flow rate continuously, offers little resistance to flow, and has a unique cartridge design that allows removal of all internal parts as one assembly.The meter also exhibits little sensitivity to gas density above two atmospheres pressure.The low inertia of the rotor and vee bearings, allows overhanging of the meter to twice its rated capacity, without damage for intermittent flow variations.  Orifice plates and venturi tubes rely on detecting the differential pressure across a restriction in the pipe,and this pressure is directly proportional to the media velocity. Given knowledge of the pipe dimensions and media characteristics,a differential pressure instrument can give a reading directly in flow units. The accuracy of these systems are reliant on very fine tolerance machining of the orifice or venturi and the pressure drop incurred,through the installation of these devices may not suit all situations. These can be highly accurate and reliable but are expensive and complicated to install and maintain. Pitot tube systems work on a very similar principle and remove the issue of the pipe restriction,as there is only a small diameter tube inserted at right angles to the flow. These can be inserted through ball valves, making removal for service or calibration very simple. This method does not need perfectly dry and pure gases to be accurate,and is very tolerant of wet gases and contaminants which makes it ideal for measuring in difficult places. Such as compressor outlets. Vortex meters place a bluff restriction in the pipe,that causes vortices to form alternately on the 2 rear edges. Sensors are used to detect the formation of these vortices, the frequency of which is directly proportional to the flow rate. These instruments are accurate but again introduce a large restriction into the pipe,and are often employed on steam applications.

What about Thermal Mass?

Thermal mass meters and calorimetric flow sensors sense the cooling effect on a heated element,which is directly proportional to the mass flow rate rather than the volumetric flow rate. This removes the subsequent calculations needed to determine mass flow rate,using other methods of flow measurement, and there is no pressure or temperature compensation necessary.The actual sensing tips are small and thus the restriction placed,in the pipe produces very little back pressure, making this method ideal for very low and very high flow rates.Thermal mass meters are available in a range of accuracies and are ideal for dry, clean gas flow measurement. Some designs have all stainless steel wetted parts making them better suited to contaminated or corrosive gases,which would damage the exposed sensing elements of unprotected designs. They are not suitable for wet gases or steam. For those applications a pitot tube design or possibly a vortex meter would be the better choice. Thermal mass is also an excellent principle for use in flow switches,as there are no moving parts in the media and the sensor produces very little back pressure due to its minimal size. These flow switches are very sensitive and some models can be used to determine flow direction as well as flow/no flow.

In line flow meter

In line flow meter is currently the mainstream measuring instrument in flow measurement.

In line flow meter is an in-situ display flow meter, also called integrated flow meter. The display head and sensor are integrated.

At present, all integrated flow meters belong to the In line flow meter. They all have in-situ display function. For example, the split-type flow meter does not have the in-situ display function, and its meter and sensor are connected by conduction.

What are the advantages of in line flow meter in the flow measurement process?

In some measurements with a control system, the advantage of In line flow meter is not great. Because the flow can be monitored through the PLC system.

In working conditions without a PLC system, In line flow meter can show its advantages. It can display cumulative flow and instantaneous flow online.

Remote flowmeter

Remote flowmeter is also called split flowmeter. Compared with the online flowmeter, the remote flowmeter means that the sensor and the display are installed separately.

For example, the flow sensor is installed in the underground water pipe, but for the convenience of viewing the data, the display is installed on the ground. The sensor and the display can be connected via a signal cable.

If you let me answer this question. I would like to divide flow meters into two categories: mass flow meters and volumetric flow meters.

Of course, it can also be divided according to the measurement medium. There are two types of flow meters for measuring gas and measuring liquid.

Perhaps, we can also divide into closed pipeline measurement and open channel measurement according to the situation of the pipeline.

Finally, we may also be able to divide into contact and non-contact measurements according to the contact situation of the medium.

If you want to divide the flow meter into three categories. I think it can be divided into volumetric flowmeters, mass flowmeters, and velocity flowmeters.

There are differences in the allowable error of the measurement accuracy of the commonly used flowmeters, as follows.

  • Mass flow meter 0.05%;
  • Positive displacement flowmeter 0.25～0.5;
  • Electromagnetic flowmeter 0.25～1.0;
  • Turbine flowmeter 0.15～0.5;
  • Vortex flowmeter 0.15;
  • Ultrasonic flowmeter 0.10 (multi-channel is better than 0.5);
  • Orifice plate, micro cone, uniform velocity tube flowmeter 1 to 1.5, nozzle 0.10.

Relatively speaking, mass flow meters have the highest accuracy.

Both the accuracy and error of a flowmeter characterize the ability of a measuring instrument to approximate the actual true value of the measurement results. The higher the accuracy of the instrument, the closer the measured value is to the actual true value. The higher the accuracy, the smaller the error.

Many people feel that the flow meter (flow meter) is the same as the water meter to measure water, but it has the essence but different. However, a water meter is a type of flow meter (flow meter). Let’s talk about the difference between the two of them.

The flow meter (flow meter) can measure the instantaneous flow, and can understand the usage of each site. The water meter mainly has the accumulation function, and the instantaneous flow Q cannot be seen.

A water meter is also a type of flowmeter. It is a volumetric measurement with an accumulation function. The household water meter is a small flow measurement flow meter. It is not resistant to high pressure and high temperature, and cannot output linear signals. Unable to participate in the automation control of modern industry. Basically only metering water, certainly not for metering gas. Some liquid media also cannot be applied.

To put it simply, water meters are generally only used to measure water and have a wide range. Flow meters can measure liquids, gases, vapors, or two-phase.

The installation positions of different flowmeters have different requirements for straight pipe sections.

Liquid flow meters are generally better installed at low places. Because this can make the part of the liquid passing through the flow meter reach the state of full pipe.

Gas flow meters are generally installed high in the pipeline.

And almost all flow meters require a certain length of straight pipe. Different flow meters require different straight pipe lengths.

If there is anything you want to know, please contact us.

The general measurement is to use an electromagnetic flowmeter.

Magnetic flowmeters use the principle of Faraday’s Law of Electromagnetic Induction to measure the flow rate of liquid in a pipe. In the magnetic flowmeter pipe parts, a magnetic field is generated and channeled into the liquid flowing through the pipe.

As fluid flows through the magnetic field, conductive particles in the fluid create changes. This variation is used to measure and calculate the velocity of water flow through the pipe. When the fluid moves faster, more voltage is generated. The electronic transmitter processes the voltage signal to determine the liquid flow.

A meter that measures the total flow rate based on the efficacy of the fluid fluidity on the ultrasonic beam (or ultrasonic single pulse).

The thermal flowmeter sensor includes 2 sensing technology components. A speed sensor and a temperature sensor. They compensate and calibrate the gas temperature changes fully automatically.

The electric heater part of the instrument heats the speed sensor to a certain time constant higher than the temperature of the working condition. A stable temperature difference is generated between the speed sensor and the sensor that measures the temperature of the working condition.

When the temperature difference does not change, the kinetic energy consumed by the electric heater. It can also be said that the heat dissipation value is proportional to the mass flow rate of the passing gas. It is suitable for the measurement of single gas and a fixed proportion of multiple gases.

The basic principle is to use the Coriolis force caused by the fluidity of the fluid in the vibrating tube. The force can be measured immediately or indirectly to obtain the fluid mass flow.

Gas mass flow meter working principle

The thermal flowmeter is a flowmeter designed based on the principle of thermal diffusion.

That is, when the fluid flows through the heat-generating object, the heat loss of the heat-generating object is proportional to the flow rate of the fluid.

The sensors of the series flowmeter have two standards RTD,

one for the heat source, and one for measuring the temperature of the fluid.

When the fluid flows, the temperature difference between the two is linear with the flow rate,

and then the relationship is controlled by microelectronic control technology.

Converted to a linear output that measures the flow signal.

During the unit British period, the filter passes through a certain volume of air flow. We generally use m3/h air volume unit. Foreign countries also use m3/h air volume unit cfm (cubic feet per minute). That is, ft3/min cubic feet/minute.

Commercial conversion is: 1cfm≈1.7m3/h.
