The ultrasonic water flow meter is a commonly used water flow meter. It can be installed with an external clamp, Insertion installation, pipeline installation, etc. Hand-held clamp-on ultrasonic flowmeters are very popular for their ease to use.
Use a portable ultrasonic flowmeter to test the pipeline of the entire system, which can reveal the location of the leak.
The portable flow meter allows the operator to compare the flow rate and the total flow rate at various points in the system.
The low flow at the site indicates that there is a leak nearby. This method is non-invasive and does not require cutting the pipe.
Two ultrasonic flowmeters, one is installed on the water outlet pipe of the reservoir, and the other is installed at the critical intermediate position where the pipe is spread from underground to the ground.
As long as the measurement of the two flowmeters is the same, it means that there is no water leak in the buried pipe network. On the contrary, there is water leak.
When a single conduit in a complex piping configuration is compromised, it can be challenging to locate the precise point where the leak occurred. If you observe an increase in overall water consumption without making any changes, it is likely that a pipe has cracks or cracks.
Transit time Ultrasonic Flow Meter adopts the measurement principle of time difference method. It uses the ultrasonic wave emitted by the sensor to propagate in the flowing fluid. The sound wave propagation speed in the downstream direction will increase, and the backward direction will decrease. In the same propagation distance, there will be different transmission times. According to the difference between the transmission time and the measured The relationship between fluid velocity measures the fluid velocity.
The flow rate of the fluid is different in different positions in the tube. The flow rate in the center of the tube is faster than the flow rate near the wall of the tube. The flow velocity distribution of the fluid in the pipeline can be represented by the flow velocity cross-sectional distribution diagram.
Notes: V measure fluid velocity M ultrasonic reflection times D pipe diameter θ The angle between the ultrasonic signal and the fluid T up The time when the downstream sensor transmits the signal to the upstream T down Time from upstream sensor to downstream ΔT = T up – T down

In addition to the water meter described at the top of this article. We also have many types of water meters. Such as turbine water meter. Ultrasonic water meter. Electromagnetic water meter, etc.
The types of water meters can be divided by the principle of measurement, the common types are:
a) Mechanical water meter: Measuring sensors, calculators and indicating devices are all water meters with mechanical principles and structures. There are mainly speed water meters and volumetric water meters.
b) Mechanical water meter with electronic device: The mechanical water meter with complete structure is retained, and the water meter with an electronic device is installed on this basis, mainly including IC card water meter and remote water meter. The measuring sensor of the mechanical sensor electronic water meter is composed of a sensor based on the principle of mechanical motion and a sensor element that can convert the mechanical motion into an electrical signal and input into the calculator. Both the calculator and the indicating device are electronic components, such as a vortex (impeller) wheel electronic water meter.
c) Electronic water meter: Electronic water meters are divided into mechanical sensor electronic water meters and electronic sensor electronic water meters. The measuring sensor of the electronic water meter is based on the principle of electronic or electromagnetic induction. Both the calculator and the indicating device are electronic components. Such as ultrasonic water meter, jet water meter, Coriolis water meter, and electromagnetic water meter.
What is the working principle of the water meter? It’s actually very simple. Because the housing of the water meter is fixed. Its internal volume is fixed. And the water is flowing. It pushes an impeller to rotate. Whenever the impeller rotates, there is a constant volume of water flowing through. Therefore, as long as the number of revolutions of the impeller is accumulated and multiplied by this constant volume, the total amount of water flowing through can be obtained.
The diameter of the water meter should be determined according to the diameter of the installation pipeline. The installation position should avoid exposure, flooding, freezing and pollution, and it is convenient to disassemble and swipe.
The water meter should be installed horizontally (display face upward).
The sand, gravel, hemp and other sundries in the pipeline should be removed before new installation to avoid malfunction of the water meter.
The direction of the arrow shown on the water meter should be consistent with the direction of water flow in the pipeline.
If the water meter is installed at the water inlet of the boiler, it is necessary to prevent the return of hot water and steam from the boiler from damaging the internal parts of the water meter. It is best to install a check valve at the water outlet of the water meter.
The prices of water meters vary. The price of the water meter is mainly determined by the material, caliber, and function. For example, residential water meters. 3/4 inch, without special function, reference price USD95.00/pc.
For the specific water meter price, please contact our sales engineer for confirmation.

The analog flow meter is a flowmeter with the analog output signal. Analog output is a common function of flow meters. The analog signal is mainly used to output the flow signal to the next control system.
Analog signal: poor confidentiality, weak anti-interference ability.
Digital signal: strong anti-interference ability and good communication confidentiality.
Digital signal, as the name implies, means that the independent variable is discrete. And the dependent variable is also a discrete signal. The independent variable of a digital signal is represented by an integer. Its dependent variable is represented by a limited number. The digital signal uses two physical states to represent 0 and 1. Therefore, the quality of the digital signal is very strong, and the anti-interference ability is also relatively strong.
The analog signal refers to the continuous signal of the information parameter in a given range. The characteristic quantity of the information of the analog signal can be transformed into an arbitrary numerical signal in an instant. In the process of transmitting analog signals, the information signals need to be converted into electric wave signals, which are then transmitted through wired or wireless methods.
If you need to know the flow rate in you pipe, or river, that when you need a flow meter. So, flow meter is the instrument that can finish the flow measurement.
Flowmeters consist of a primary device, transducer and transmitter.
The transducer senses the fluid that passes through the primary device.
The transmitter produces a usable flow signal from the raw transducer signal.
These components are often combined, so the actual flowmeter may be one or more physical devices.
Different types of flow meters are available for different applications, and depending upon the requirement, a careful selection of flow meters is made.
For e.g., we prefer vortex flow meters flow steam flow measuremnet. And we like the ultrasonic flow meters for non-contact pipe flow measuremnt.
A turbine-type flow meter cannot be used for measuring the flow in an unclear liquid (wastewater or corrosive liquids).

Inline water flow meters are instruments that can be installed directly on water flow pipes to display flow. In principle, there are mechanical, ultrasonic, electromagnetic, and so on. Used in residential water pipes or industrial water pipes.
An inline flow meter is a flow meter with the function of displaying flow rate on-site. The sensor of the flow meter is installed on the fluid pipe. Digital display or pointer shows the flow rate on the spot.
In-line flowmeters could be digital and mechanical flow meters. Common in-line flowmeters include turbine flowmeters, electromagnetic flowmeters, and ultrasonic flowmeters. With stainless steel material, analog, and 4-20mA output, in-line flow meters can measure and control inline flow.
The residential inline water flow meter is an essential thing in modern residents’ homes. The residential inline water flow meter is used to measure household water consumption. It is also the basis for the water company’s charges.
Domestic inline water meters are provided and installed by the water supply company.
The price of the water meter is determined according to the function of the water meter. At present, the water meters on the market are divided into mechanical water meters, IC card water meters, remote water meters, photoelectric direct reading water meters, NB-IoT Internet of things water meters, etc. The prices are different for different levels.
Generally speaking, the price of mechanical water meters is relatively cheap. The price of smart water meters is more expensive. At present, the relatively new type is the NB-IoT remote transmission water meter, which is convenient for meter reading, mobile phone operation, no wiring, and wireless transmission of signals.
Divided according to the functions used, the smart IC card water meter is more commonly used now. That is to say, this smart water meter has an IC card inserted into the water meter. You can query the water consumption at home and the water bill.
And one of its biggest features is that it can pay water charges in advance. It can also solve the trouble of water company charges. Before, it was necessary for staff to go door-to-door to read the meter. With this smart IC card, it can be inquired remotely.
Now a remote water meter has been developed. According to its literal meaning, it can also be understood that this kind of water meter is also very intelligent. There is no need to go to the house to read the meter. The staff can understand the water consumption of each customer in the office. It also brings a great deal to the water supply company.

Mechanical water flow meter
A mechanical water flow meter relies on the kinetic energy of the water flow to drive the metering mechanism to work. The water flowing through the water pipe impacts the water meter impeller and then drives the gear to rotate, without electricity.
The mechanical water flow meter is currently used less, mainly due to the following reasons:
There are many vulnerable parts, and the existence of the movable part impeller is easy to cause fouling of itself and the measuring cavity. Even blockage, especially when the water quality is poor. Therefore, the reliability and stability of the work are relatively low;
The movable part of the impeller shaft core is easy to wear after a long time or high flow rate operation. Especially when the water quality is corrosive. Therefore, the durability of work is low, and the service life is relatively short;
The presence of the impeller in the measurement chamber will produce a large pressure loss. Reduce the transmission capacity of the heating pipe network. In particular, it brings difficulties to the transformation of the old pipe network;
The accuracy of flow measurement is relatively low. There are also certain requirements for the flow rate of the fluid. Can not effectively measure when the flow rate is low.
Compared with a Mechanical inline water flow meter, a Digital flow meter makes it easier for users to obtain flow information.
Digital flow meter generally has a digital display. The traffic can be displayed locally. Including instantaneous flow and cumulative flow. It can even display information such as pressure and temperature.
Digital flow meter generally also supports remote data transmission. Digital flow meter outputs pulse, 4-20mA, and other signals. Support HART, RS485, and other protocols. Even wireless remote transmission.
The flowmeter is produced according to the user’s measurement parameters. Therefore, the price of the flowmeter is different for different measurements.
Important factors when selecting flow metering devices are
accuracy
cost
legal constraints
flow rate range
head loss
operating requirements
maintenance
lifetime
These factors are more or less related to each other. For example – the cost of flow meters increases with accuracy and lifetime quality.
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.
Flowmeter usually refers to industrial flow meters. Water meter usually refers to the residential water meter.
Industrial VS residential digital water flow meter
1. From a functional point of view. Industrial digital water flow meter mainly measures instantaneous flow. It is a real-time state. It can understand the usage of each site. And can output pulses, 4~20mA, etc. The residential digital water flow meter is mainly a cumulative function, generally cannot see the instantaneous flow.
2. From the cost point of view. The manufacturing cost of the Residential Digital Water Flow Meter is relatively low. The cost of an Industrial Digital Water Flow Meter is generally relatively high.
3. In terms of quality. Relatively speaking, the Residential digital water flow meter has poor accuracy. It cannot withstand high pressure and high temperature, and cannot output linear signals. It cannot participate in the automation control of modern industry. The industrial digital water flow meter can do the above.
4. From the point of view of usage. Residential digital water flow meter only measures water and is not used to measure gas. And some liquid media water meters cannot be used. Industrial digital water flow meter liquids (water, oil, turbid liquids, etc.) can be measured.
Of course, Residential digital water flow meters can realize various functions such as prepayment. Remote data transmission. Remote valve control. Step water pricing, etc. It is a must-use metering product for residential homes.

Intelligent digital display quantitative control instrument is one of the items that many enterprises will use or need to improve at present.
For the traditional controller dosing control system in the production process of complex work, poor precision and other shortcomings. It is developed and produced with PLC as the main body and touch screen or LCD as the auxiliary dosing control box. It has many advantages such as easy to operate and learn, good working stability and powerful function. It can directly replace manual dosing, manual dosing, and the accuracy is better than manual. At the same time, this system has the characteristics of intuitive display, manual control or automatic control combination.
Industrial Petrol/Diesel Quantitative Control Systems are especially suitable for oil blending, water blending, chemical blending, dosing, water injection and quantitative or steady flow control of various liquids, gases or steam. It is especially suitable for enterprises that still use manual operation for tank filling/batching/dosing and do not want to invest too much cost, but want to improve the working efficiency.
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.
Industrial Fuel oil flow meters measure the volume or mass of fuel oil. Can realize the mutual conversion of volume and mass.
The main industrial oils are hydraulic oil. Gear Oil. Turbine oil. Compressor oil. Refrigeration oil. Transformer oil. Cylinder oil, heat treatment oil, heat transfer oil, etc. Of course, edible oil can also be produced in the industry. In addition, there are greases with lubricating oil as base oil and thickening agent.
Therefore, whether it is a company that uses, trades, or produces oil, it needs to accurately measure the oil flow.
There are many common oil flow meters, such as turbine flow meters, positive displacement flow meters, gear flow meters, mass flow meters, etc.
Positive displacement flow meters and turbine flow meters are often used as gasoline flow meters because of their high accuracy and repeatability and their ability to directly measure the volume of gasoline.
Fuel flow meter refers to a type of flow meter that can measure the volume flow or mass flow of fuel in the pipeline with high accuracy. For example, turbine flow meters, elliptical gear flow meters, etc.
Normally, our fuel flow meters have a local display. In particular, digital fuel flow meters can display both instantaneous and cumulative flow rates. Alternatively, you can use the flow rate calculation tool: Flow Velocity & Pipe Diameter to Volumetric Flow Rate Calculator
The gasoline pump measures fuel by using a gasoline flow meter (e.g. PD flow meter, turbine flow meter). The operator sets a set value based on currency/liter. The flow meter instantly calculates the volume by splitting it into smaller volumes. and ultimately measures the number of liters of fuel dispensed.

Cheap flow meters means to choose the lowest cost flow meter while satisfying your measurement needs. How to choose the lowest cost flow meter?
Cheap flow meters are not equal to any flow meter. Different flowmeters are required to measure air velocity, water, and other liquids. For example, if you need to measure water flow rate, electromagnetic flow meters and ultrasonic flow meters are more suitable. On top of this, let’s choose a low-cost configuration.
The measurement of water flow is the most widely used method in industrial production. Raw water, domestic sewage, industrial wastewater, etc. all need to be monitored. So how to choose a low-cost water flow meter?
Here, Sino-Inst proposes the following suggestions for you based on experience:
If it is measuring drinking water, beverages, etc. Sanitary electromagnetic flowmeters can be used. Meet the requirements of drinking and hygiene.
If it is industrial wastewater or corrosive liquid, you can choose electromagnetic flowmeter. Choose the lining made of tetrafluoroethylene and the electrode of 316L, which can resist corrosion.
If it is residential water, you can use an ultrasonic water meter. Simple to use. low cost.
If it is a short-term measurement requirement, or for convenience, you can choose an external ultrasonic flowmeter. The host can be handheld or wall-mounted, and the cost is extremely low. And can be applied to different pipe diameter measurement.
Of course, the above is only Sino-Inst’s suggestion. In order to choose the right water flow meter, you can contact our sales engineer. According to your measurement medium, pressure, pipe diameter, use function, accuracy and all requirements, choose the best cost flowmeter.
Mechanical water flow meters refer to a type of flow meter suitable for clean water processes or applications. The working principle of a mechanical water flow meter is to measure the speed of water flowing through a pipe. This causes the piston or turbine to rotate. The volume flow of water is proportional to the rotation speed of the blades. Compared with electronic water flow meters, mechanical water flow meters may become clogged when the water is dirty or contains large particles. When the water flow is low, the mechanical water meter does not work well.
Ultrasonic flow meters, especially clamp-on ultrasonic flow meters, have a very high cost performance. Especially compared to large diameter pipes. For example: measuring water in large diameter pipes. Either an electromagnetic flowmeter or a turbine flowmeter can be used. But their costs are not low. At this time, the cost of the clamp-on ultrasonic flowmeter will be much lower.
There are 4 types of gas flow meters commonly used in industrial production and trade calculations. They are vortex flowmeter, precession vortex flowmeter, rotameter, differential pressure flowmeter, etc.
The cost of these gas flow meters is different. It is necessary to select the appropriate model according to the actual measurement parameters and confirm the cost.
Flow meters are classified into liquid flow meters and gas flow meters according to the medium. Then the common liquid flow meters mainly include: vortex flowmeter, turbine flowmeter, electromagnetic flowmeter, ultrasonic flowmeter, differential pressure flowmeter, open channel flowmeter, Coriolis mass flowmeter, etc.
Digital Fuel Flow Meter is a flow meter dedicated to measuring fuel, diesel, gasoline, and petroleum. Digital Fuel Flow Meter generally has a digital display or signal output. Such as pulse or 4-20mA. Such as turbine flow meters, gear flow meters. It can be used to measure the pipeline flow of oil medium storage, transportation, trade, etc. Different pipelines and working conditions require flow meters with different principles or functions. Next, we will analyze in detail.
Water flow meters are flow meters that can diaplay the flow rate of industrial water pipe.
A water flow meter measures the amount of water flowing through a pipe. We have several kinds to choose from, depending on the application, maintenance needs, and budget.
There are four common water flow meter types:
Turbine (also called mechanical), Vortex, Ultrasonic, and Magnetic. We will tell you everything you need to know about them and help you choose one for your application.
Low Flow Meters refer to those flow meters that can be used to measure micro-flow-low-flow rate media. Including metal rotor type, gear type, electromagnetic type microflow meter, microturbine type, and thermal type small mass flow meter. It can measure the Low flow rate of a variety of liquids and gases. For example, it needs small volume, high-temperature resistance, low-temperature resistance, or medium viscosity. etc. We all have suitable product recommendations.
Generally speaking, the accuracy of Coriolis mass flow meters is relatively high. High precision: standard configuration ±0.2%, ±0.1%, ±0.05% optional. However, general industrial liquid flow measurement does not require such high accuracy. An accuracy of 0.5% or 1% is sufficient. You can choose the appropriate flowmeter according to the measurement requirements. Extended reading: Micro flow meters for low flow liquids
Generally, it needs to be measured according to the measured medium, use environment, installation method and other aspects. If it is ordinary non-corrosive water, it is USD300-500. The specific decision is based on different site conditions. The price of electromagnetic flowmeters is determined according to the measured medium. Different mediums, ranges, installation methods, and prices will vary greatly.

Sino-Inst offers a variety of Digital gas flow meters for flow measurement. If you have any questions, please contact our sales engineers.
Are you looking for a flow meter for measuring gas volume or mass flow? For Air-O2-N2-CO2 etc.
Every day, in the production process, the production or consumption of various gases may need to be metered. Accurate gas measurement is important work.
Sino-Inst offers volumetric or mass flow meters available for various gases. If you don’t know how to choose the right Digital Gas Flow Meters. Please contact our sales engineer and we will provide you with a quotation based on your measurement needs.
First, you can start with your measurement needs. Do you need to get the volume flow or mass flow of the gas being measured?
Velocity gas flow meters generally consist of a flow sensor and a display.
For occasions where temperature and pressure change, a pressure gauge (sensor or transmitter), a thermometer (sensor or transmitter), a flow totalizer (temperature and pressure compensation) or a flow computer (temperature, pressure and compression factor compensation) are required.
For occasions with higher accuracy requirements (such as trade natural gas), an online chromatograph is also configured to continuously analyze the components or physical properties of the mixed gas to calculate the compression factor, density, calorific value, etc.
The main industrial applications are:
① Turbine flowmeter: When the fluid flows through the turbine flow sensor, the turbine is forced to rotate under the action of the fluid thrust. Its rotational speed is proportional to the average flow velocity of the pipeline. The rotation of the turbine periodically changes the reluctance value of the magnetoelectric converter. The magnetic flux in the detection coil follows Periodic changes occur, generating periodic electrical pulse signals. In a certain flow (Reynolds number) range, the electrical pulse signal is proportional to the volume flow of the fluid flowing through the turbine flow sensor.
②Vortex flowmeter: A bluff vortex generator is placed in the fluid. The fluid is alternately separated on both sides of the vortex generator to release two regular rows of alternating vortex streets. In a certain flow (Reynolds number) range, the separation frequency of the vortex is proportional to the volume flow of the fluid flowing through the vortex flow sensor.
③ Precession turbine flowmeter: When the fluid passes through the spinner composed of helical guide vanes, the fluid is forced to rotate strongly around the centerline to form a vortex turbine. The center of the vortex precesses along a conical spiral when passing through the enlarged tube. In a certain flow rate (Reynolds number) range, the precession frequency of the vortex flow is proportional to the volume flow of the fluid flowing through the precession vortex flow sensor.
④Time difference ultrasonic gas flowmeter: When ultrasonic waves pass through a flowing fluid, within the same propagation distance, their propagation velocities are different in the forward flow direction and the countercurrent direction. In a wide range of flow (Reynolds number), the time difference is proportional to the volumetric flow (average velocity) of the fluid being measured in the pipe.
The gas volumetric flowmeter is a mechanical instrument. It is generally composed of a measuring body and a totalizer. For occasions where temperature and pressure change, a pressure gauge (sensor or transmitter), a thermometer (sensor or transmitter), a flow rate Totalizer (temperature and pressure compensation) or flow computer (temperature and pressure and compression factor compensation).
Inside the positive displacement flowmeter, there is a fixed large space and a set of rotating bodies that divide the space into several small spaces of known volume. Such as waist wheel, membrane, drum, scraper, oval gear, piston , screw, etc.
The rotating body rotates continuously under the action of the fluid pressure difference, and continuously discharges the fluid from a small space of known volume.
According to the number of rotations of the rotating body in a certain period of time, the volume of fluid flowing through can be obtained.
In the standard state, the volume flow calculation formula of the positive displacement flowmeter is the same as that of the velocity flowmeter.
Differential pressure flowmeter is based on Bernoulli equation and fluid continuity equation. According to the throttling principle. When the fluid flows through the throttling part (such as standard orifice, standard nozzle, long diameter nozzle, classic venturi nozzle, venturi Sharp nozzle, etc.), a pressure difference is generated before and after it. This differential pressure value is proportional to the square of the flow.
Among the gas flowmeters, the standard orifice plate throttling device differential pressure flowmeter is the most widely used because of its simple structure, low manufacturing cost, most complete research and standardization.
Thermal Mass Flow Meter can directly measure the mass flow of various gases. Unaffected by changes in viscosity, density, temperature, or pressure.
Thermal Mass Flow Meter is a true mass flow meter. No temperature and pressure compensation is required. Thermal gas mass flow meters are designed based on the principle of thermal diffusion. Including natural gas, coal gas, liquefied gas, flare gas, argon, carbon dioxide and other mixed gas flow measurement.
Nitrogen is required in many processes of the chemical and pharmaceutical industry; predominantly as protective gas, to prevent the occurrence of explosive atmospheres。
Such as when handling dusty products or solvents.
If your work requires you to use nitrogen, having a flow meter installed on your tank is a great way to save some money.
These indicators let you know whether gas is moving through the line, often via the use of a levitating ball, a pressure gauge, or other visual cue.
These options are simple to use and reliable, making them must-haves for welders, HVAC technicians, and more.
Please follow the purchasing guide below. You will find your most suitable Nitrogen flow meter!
Compressed Air Flow Meter is the digital flow meter work for the air compressor. Air consumption is an important info for industrial inline gas flow pipe. According to the measurement conditions, compressed air flow meter could be different types. Thermal mass flow meters, Ultrasonic flow meters, Vortex flow meters, Turbine flow meters. And the differential pressure flow meters (Orifice plate ) are also suitable for compressed air. With the Pressure and Temperature compensation. Sino-Inst’s compressed air flow meters are more affordable and complete.
Oxygen Flow Meters are digital flow meters that can measure industrial oxygen. It is very important to choose a suitable flow meter to measure and monitor the oxygen flow.
Oxygen and hydrogen are special gases, so you must choose a suitable flow meter. Several commonly used flow meters that can measure oxygen are precession vortex flowmeters, vortex flowmeters, DP flowmeters, and thermal gas mass flowmeters. The selection of oxygen flow meter must provide specific parameters, such as pipe diameter, working pressure, temperature, flow range, functional requirements, and so on.
CO2 flow meters are instruments that can measure the flow of gaseous or liquid carbon dioxide. CO2 is a common industrial gas, and effective measurement is very important.
Carbon dioxide (CO2) is a colorless, odorless, or colorless odorless gas at room temperature and pressure. We often recommend precession vortex flowmeters, v-cone flowmeters, vortex flowmeters, gas turbine flowmeters, etc. Under different working conditions, we will choose different flow meters for customers.
Biogas Flow Meters are instruments that can measure the flow of biogas. Could be a vortex flow meter, thermal mass flow meter, etc. Commonly used in biogas stations, biogas production fermentation tanks, etc.
Biogas Flow Meters measure the flow of biogas in the production and use process. At present, several biogas flow measurement technologies have been widely used in the biogas field, including turbine flow meters, vortex flow meters, orifice flow meters, ultrasonic gas flow meters, etc.
LPG flow meter is used for flow measurement of liquefied petroleum gas. The flow measurement of LPG is very important in industrial production, transportation and trade settlement.
LPG gas (Liquefied petroleum gas) is a kind of hydrocarbon with propane and butane as its main components. LPG is used for heating, motor fuel, industrial applications, and agriculture. LPG can be in a gas or liquefied state. Different types of industrial LPG flow meters with accurate and reliable performance. Such as thermal dispersion flow meter, Coriolis flow meter, gas turbine flow meter, vortex flow meters.
A propane flow meter refers to a flow meter that can measure the volume or mass flow of propane gas. Also often called LPG gas flow meter.
Propane is also generally referred to as liquefied petroleum gas (LPG). So what is the difference and connection between propane and LPG? Next, let’s take a look together.
Natural Gas Flow Meter

At present, the flowmeter products used for natural gas flow measurement roughly include: gas waste wheel flowmeter, gas turbine flowmeter, precession vortex flowmeter, thermal mass flowmeter, vortex flowmeter, ultrasonic flowmeter, and orifice flowmeter Wait. Let’s make a simple comparison on the use of these flow meters.
Steam flow measurement has always been a problem. Today we solve a problem of temperature and pressure compensation. So Do you need temperature and pressure compensation for Steam Flow Measurement?
There are two types of steam, saturated steam and superheated steam. The temperature and pressure compensation is superheated steam. For the real saturated steam, only temperature or pressure compensation is required. Check the density table according to the temperature and pressure during measurement to obtain the required mass flow.
The gas velocity in the pipeline is the basis for calculating the gas flow. The way to measure the gas flow rate is direct measurement or conversion through pressure measurement.
Enterprises usually use Pitot tubes (or dynamic pressure velocimetry tubes) to measure the dynamic pressure of the fluid in the pipeline first, and then calculate the flow velocity and average flow velocity at this point (the average flow velocity should be used to find the gas flow).
Because the velocity measuring tube is used to measure the velocity of the pipeline, it is only the local velocity of a certain point on the pipeline section. The flow velocity at each point on the pipeline is not the same. It is necessary to measure the flow velocity at multiple points on this section. Find the average dynamic pressure to calculate the average flow velocity.
There are many types of gas flow meters. Such as common thermal mass flowmeters, vortex flowmeters, differential pressure flowmeters, etc. Different kinds of gas flow meters are based on different working principles.
The working principle of gas flowmeter, the common types are as follows:
Thermal gas mass flowmeter: designed based on the principle of thermal diffusion, the instrument uses the constant temperature difference method to accurately measure the gas. The sensor section consists of two reference grade platinum resistance temperature sensors, suitable for the measurement of all gas flow meters (except acetylene)
Precession vortex flowmeter: adopts the latest micro-processing technology. It has the advantages of strong function, wide flow range, operation and maintenance verification, convenient installation and use, etc. It is widely used in various gases such as petroleum, chemical industry, electric power, metallurgy, coal, etc. Measurement of liquids.
Turbine flowmeter: a speed meter. It has high precision, good repeatability, simple structure, high pressure resistance, wide measurement range, small size, light weight, small pressure loss, long life, simple operation, convenient maintenance, etc. Advantages. It is used to measure the volume flow and accumulation of low viscosity, non-corrosive, clean liquids in closed pipelines. It can be widely used in petroleum, chemical, metallurgy, organic liquid, inorganic liquid, liquefied gas, city gas pipeline network, pharmaceutical, food, papermaking and other industries.
Vortex flowmeter: The principle of Karman vortex is adopted. A triangular column-shaped vortex generator is set in the fluid, and regular vortices are alternately generated from both sides of the vortex generator. This vortex is called Karman vortex, and the vortex flowmeter is the current One of the main flow meter products in the world. It is widely used in petroleum, chemical, metallurgy, heating and other departments. Detect and measure the flow of liquid, gas and steam.
Differential pressure flowmeter: Differential pressure flowmeter is based on Bernoulli equation and fluid continuity equation. According to the throttling principle, when the fluid flows through the throttling part (such as standard orifice, standard nozzle, long Diameter nozzles, classic venturi nozzles, venturi nozzles, etc.). There is a pressure difference before and after it, and this differential pressure value is proportional to the square of the flow. Among the gas flowmeters, the standard orifice plate throttling device differential pressure flowmeter has a simple structure and low manufacturing cost. It has been standardized and has been widely used.
Mass flow meter directly measures the mass flow of the medium passing through the flow meter. It can also measure the density, temperature and viscosity of the medium
Mass flow meter is a flow measuring instrument that measures the mass flow in the pipeline. The volume of a fluid is a function of fluid temperature and pressure and is a dependent variable. The quality of a fluid is a quantity that does not change with time, space temperature, and pressure.

An electromagnetic flowmeter is a common water meter in industrial flow meters. It is a fully intelligent flowmeter. It has the function of displaying instantaneous flow and accumulated flow, and there are a variety of flow units to choose from.
And its output signal is also diversified, there are (4-20) mA, RS485, pulse, HART and other output signals to meet the needs of different working conditions.
For example, in the city water supply unit needs to measure the total daily water supply. At this time, you need to read the required data from the flowmeter. The instantaneous flow rate every hour and the cumulative flow rate within a specific time. It is very convenient to use.
Usually, flow meters measure instantaneous flow. If you need to know the total amount of flow, you need to use a totalizer.
A complete flow detection system includes several parts such as sensing, transmission, calculation, integration, display, etc. Each part can be an independent instrument. It is also possible to integrate several functions into one watch.
Many flow totalizers on the market now integrate calculation, totalization, and display. It includes most of the functions of the flow system. Some manufacturers set the totalizer and other parts as flow meters and use the name of the complete set on the totalizer. If you buy the totalizer alone, you will see that the name is flowmeter.
So the flowmeter [maybe] includes a totalizer, but the totalizer is not a flowmeter.
Our flow totalizers all support 4-20mA signals. Not just 4-20mA input signals. You can also choose to output a 4-20mA signal.
Our flow totalizers support the display of various commonly used flow units. Paperless recorders contain more units for flow, pressure, temperature, etc.
For example, with the following common units: ℃, Kgf , Pa, KPa, MPa, mmHg, mmH2O, bar, t/h, Kg/h, L/h, m³/h, Nm³/h, t/m, Kg/ m, L/m, m³/m, Nm³/m, t/s, Kg/s, L/s, m³/s, Nm³/s, t, Kg, g, Nm³, m³, L, KJ/h, KJ/m, KJ/s, MJ/h, MJ/m, MJ/s, GJ/h, GJ/m, GJ/s, KJ, MJ , GJ , V, A, KW, Hz, %, mm, rpm;
Flow meter totalizer calculation
Flow meter totalizer calculation refers to the collection of this flow at a fixed frequency.
If the acquisition frequency is 10hz, that is, 10 acquisitions per second. Accumulate the data collected each time, and divide the accumulated number by 10 to get the flow per second.
If the flowmeter is working at the maximum flow rate, we assume that the value corresponding to 20ma is 65535 (generally, the PLC analog quantity does not have such a high accuracy, so how much depends on the module).
Then double-word operations can meet the requirements. First convert the analog input value into a double word. Accumulate again. After 10 times, the accumulated value is divided by 10 and then transferred to another register. This register is the real cumulative amount.
Flow totalizer working principle
The intelligent flow totalizer is composed of four parts: measurement loop, digital panel meter, regulator and power supply.
The stabilized power supply converts the 220V power supply into a stable DC voltage as the other part of the power supply. The measurement loop processes the signal (voltage, current, etc.) sent by the flow transmitter into a voltage signal.
After A/D conversion, the signal is sent to the JC-775 dedicated central processing unit for processing, and not only to the digital panel meter. Moreover, it must be sent to the regulator, and the control or alarm signal will be output according to the regulation law after comparing with the set value.
How to realize the flow accumulation function in PLC?
First of all, it must be clear that the accuracy of using PLC for flow accumulation is far inferior to electromagnetic flowmeters and other flowmeters and flow totalizers that have their own accumulation function.
For flowmeter converters with accumulation function, the flow accumulation output of the general flow converter is pulse output. High-speed counting can be performed through the high-speed pulse input terminal of the PLC to obtain the cumulative flow.
For flowmeters with only instantaneous flow output, the flow cumulative addition operation is considered in PLC.
When doing flow accumulation in the PLC, you should not use a timer to do it. Because the timer is affected by the PLC scan cycle. It is impossible to be very accurate, and the error of the accumulated data is very large.
At present, general medium and large PLCs directly or indirectly provide the “Totalizer” function block. The essence is to simply accumulate the instantaneous flow of each acquisition cycle.
Vortex flowmeter is a speed-type flowmeter produced according to karman’s vortex principle, which can be used for the measurement and measurement of conventional gas, steam and liquid. More about : Vortex Flow Meter Working Principle
The totalizer is a secondary instrument, and its main purpose is to calculate the flow rate of the signal from the primary instrument. For example, when measuring steam, the vortex is a flow meter. Consider the fluid temperature and pressure density. The flow calculation is performed by the calculator to display the fluid quality, and the flow can be accumulated at the same time. Generally, some flow meters must be used with secondary meters. The differential pressure flowmeter calculates the flow rate through the differential pressure signal sent by the differential pressure transmitter.
The totalizer of the flowmeter refers to the converter of the flowmeter. It is a converter with totalizer, which can display instantaneous flow and cumulative flow.
