Explosion Proof Ultrasonic Level Sensors Operating Principle

Explosion-proof ultrasonic level sensors are devices designed to measure the level of liquids or solids in hazardous environments, where explosive gases or dusts are present. They are specifically constructed to prevent explosions by using materials and designs that can withstand sparks or high temperatures.

Explosion-proof ultrasonic level sensors use sound waves to measure liquid levels without touching the liquid. The sensor emits high-frequency sound waves that bounce off the surface of the liquid and calculate the distance between the sensor and the liquid level. This reading can be displayed on a screen or transmitted to a control system. These sensors are safe for hazardous environments because they don’t touch the liquid.

Different Types of Flowmeters – Technical and Application Analysis

Posted on by

Different Types of Flowmeters Flowmeters are devices used to measure the flow rate of different liquids, steam or gases in a line. They come in different types, such as mechanical, ultrasonic, and magnetic flowmeters.
Mechanical flowmeters use a positive displacement flow measuring device to determine the volume of the fluid passing through. Ultrasonic flowmeters use an ultrasonic sensor to determine the velocity of the fluid, while thermal flowmeters use heat to measure the flow rate. Orifice plates and magnetic flowmeters are some of the most common types of flowmeters used in industry.
Understanding the different types of flowmeters and their principles of operation is essential to selecting the right measuring device for a particular application.

RFQ Digital FlowMeters

What is a Flow Meter?

A flow meter is a device that measures the amount of liquid, steam or gas that passes through a specific point in a pipe or conduit. It is used in various industries to monitor and control the flow of fluids in pipelines, such as water, oil , gas, or chemicals.

Flow meters can be mechanical, electronic, or ultrasonic, and they work by measuring the velocity, volume, or mass of the fluid.

Flow meters are essential for ensuring that fluid flow rates remain within acceptable limits. And they help prevent damage to equipment and systems due to overloading or underloading. They are also critical in maintaining product quality and process efficiency.

Types of Flowmeters

There are various types of flowmeters used to measure fluid flow, including mechanical, electronic, and ultrasonic. Each type measures the flow rate of a fluid in a different way. Each type of flowmeter has its advantages and disadvantages.

We’ll take a look at the 5 main types of flowmeters that can be found on the market today. Includes differential pressure flowmeters, velocity flowmeters, positive displacement flowmeters, mass flowmeters and open channel flowmeters. More types of flowmeters from Wikipedia.

Differential Pressure (DP) Flowmeters

Differential Pressure (DP) Flowmeters measure fluid flow by detecting the pressure drop across an throttle placed in the flow path, such as an orifice plate, venturi tube, or flow nozzle. The greater the flow rate, the higher the pressure drop, and the flow rate can be calculated based on the pressure difference. DP Flowmeters are widely used due to their simplicity and low cost, and they can be used to measure both liquids and gases.

There are several types of DP Flowmeters, each with its unique design and advantages. Here are some of the most common types:

  • Orifice Plate Flowmeters: They have a circular plate with a hole in the middle that creates a pressure drop as the fluid flows through it.
  • Venturi Flowmeters: They have a conical shape that narrows down the flow path, which causes an increase in fluid velocity and a decrease in pressure.
  • Flow Nozzle Flowmeters: They have a converging inlet section, a throat section, and a diverging outlet section that create a pressure drop across the nozzle.
  • Pitot Tubes: They measure the fluid velocity by detecting the pressure difference between the stagnation point and the point where the fluid flow is parallel to the tube’s axis.

Each type of DP Flowmeter has its advantages and disadvantages, and the best choice depends on the specific application requirements.

Positive Displacement (PD) Flowmeters

Positive Displacement (PD) Flowmeters measure fluid flow by trapping and measuring the amount of fluid that moves through the meter. The principle of operation is based on the movement of the fluid through a chamber of fixed volume, causing a displacement of the fluid. The flow rate is calculated based on the number of times the chamber is filled and emptied. PD Flowmeters are highly accurate and suitable for measuring low flow rates of both viscous and non-viscous liquids.

There are several types of PD Flowmeters, each with its unique design and advantages. Here are some of the most common types, along with their advantages and disadvantages:

Type of PD FlowmeterPrinciple of OperationAdvantagesDisadvantages
Piston FlowmetersUse a piston moving inside a chamber to measure fluid flow.Highly accurate; Suitable for low to high viscosity fluidsNot suitable for measuring fluids with suspended solids
Oval Gear FlowmetersTwo oval gears rotating in opposite directionsHighly accurate; Suitable for low to medium viscosity fluidsAffected by fluid temperature and viscosity changes
Nutating Disc FlowmetersA disc that “nutates” or wobbles to trap and measure fluid flowHighly accurate; Suitable for low viscosity fluidsAffected by fluid temperature changes
Rotary Vane FlowmetersA rotor with vanes that rotate inside a chamberHighly accurate; Suitable for low to high viscosity fluidsNot suitable for measuring fluids with suspended solids

Velocity Flowmeters

Velocity Flowmeters measure fluid flow by determining the velocity of the fluid as it flows through the meter. The principle of operation is based on the relationship between the velocity of the fluid and the pressure difference created by the fluid’s motion. Velocity Flowmeters are commonly used for measuring high flow rates of fluids such as water, steam, and gases, and they are often less expensive than other types of flowmeters.

Here are some of the most common types of Velocity Flowmeters along with their advantages and disadvantages:

Type of Velocity FlowmeterPrinciple of OperationAdvantagesDisadvantages
Turbine FlowmetersTurbine rotor spins as fluid flows through itHighly accurate; Suitable for clean fluids with low to medium viscosityAffected by changes in fluid density, temperature, and viscosity
Electromagnetic FlowmetersFaraday’s Law to measure voltage generated by fluid flow through a magnetic fieldHighly accurate; Suitable for measuring conductive fluids such as water and acidsNot suitable for measuring non-conductive fluids
Vortex FlowmetersMeasure fluid flow using the principle of the Karman vortex streetHighly accurate; Suitable for clean fluids with low to medium viscosityCan be affected by changes in fluid density
Ultrasonic FlowmetersUse ultrasonic sensors to measure the time it takes for an ultrasonic signal to travel between two points in the fluid flowHighly accurate; Suitable for measuring fluids of different viscosities, densities, and conductivitiesOften more expensive than other types of flowmeters

Mass Flowmeters

Mass Flowmeters measure the mass flow rate of fluids passing through them, rather than measuring volume or velocity. They work on the principle of thermal dispersion or Coriolis effect, and they can measure the flow rate of both liquids and gases accurately. Mass Flowmeters are highly sensitive and provide accurate readings even with changes in fluid properties, making them ideal for a wide range of industrial applications.

Coriolis Meters:

Coriolis Meters measure fluid flow using the Coriolis effect. The meter consists of a vibrating tube, and as the fluid flows through the tube, it causes a change in the tube’s vibration frequency, which is measured by sensors.

The advantages of Coriolis meters include high accuracy and stability, excellent repeatability, and the ability to measure a wide range of fluids, including liquids and gases.

However, they can be costly, and their performance can be affected by the presence of solid particles or gas bubbles.

Thermal Mass Flow Meters:

Thermal Mass Flow Meters measure the mass flow rate of fluids by detecting the heat transfer from a heated element to the fluid. As the fluid flows over the heated element, it cools it down, and the change in temperature is measured by temperature sensors.

The advantages of Thermal Mass Flow Meters include high accuracy, the ability to measure both liquids and gases, and their simplicity of design.

However, they can be affected by changes in fluid temperature and viscosity, and they may require recalibration if the fluid properties change.

Open Channel Flowmeters

Open Channel Flowmeters are used to measure the flow rate of liquids in open channels, such as rivers, streams, and irrigation canals. They work by using a primary device, such as a flume or weir, to create a constriction in the channel, which causes the liquid to rise and flow through the device. The flow rate is then determined by measuring the height of the liquid above the device and using a formula to calculate the flow rate.

Type of FlowmeterPrinciple of OperationAdvantagesDisadvantages
FlumesSpecially designed constrictionHigh accuracy, low cost, ease of installationAffected by changes in channel shape, require certain amount of head loss
WeirsSharp-crested structureHigh accuracy, low cost, ease of installationAffected by changes in channel shape, require certain amount of head loss
Area-Velocity MetersMeasure velocity at multiple points and combine with cross-sectional areaHigh accuracy, measure flow rates in irregular channels, measure both forward and reverse flowMore complex and costly than other open channel flow meters
Ultrasonic Doppler MetersUse sound waves to measure velocityHigh accuracy, measure flow rates in irregular channels, measure both forward and reverse flowAffected by changes in liquid’s acoustic properties, may require calib

How to select a flow meter?

What Is a Torque Transducer? How to Choose?

Posted on by

Torque transducers are essential tools in many industries that rely on precise measurements of rotational forces. These devices play a crucial role in measuring the torque produced by engines, motors, and other rotating systems.
Whether you’re working in the automotive, aerospace, or manufacturing industry, understanding what a torque transducer is and how to choose the right one is crucial for optimizing performance and ensuring accuracy.
In this blog post, we’ll explore everything you need to know about torque transducers, including their types, applications, and factors to consider when selecting one for your specific needs.

RFQ Torque Sensors

What is torque?

Torque is a term used to describe the twisting or rotational force applied to an object. You can think of it as the force that causes an object to rotate around a fixed axis, like a wheel turning on an axle.

Torque is measured in units of force times distance, such as pound-feet or newton-meters.

In everyday life, you might experience torque when tightening a bolt with a wrench or using a crank to turn a wheel.

In the world of engineering and physics, torque plays a critical role in understanding how machines and engines work, and how to measure and optimize their performance.

More about torque definition and calculation.

What Is a Torque Transducer?

A torque transducer is a device that measures the amount of twisting or rotational force (torque) applied to a rotating system.

It’s like a scale for measuring the torque produced by machines and engines.

Torque transducers can be used in a wide range of industries, such as automotive, aerospace, and manufacturing, to optimize performance and ensure accuracy.

There are different types of torque transducers, including strain gauge, magnetoelastic, and optical, which work by different principles to measure torque.

By providing accurate measurements of torque, torque transducers help engineers and technicians understand how machines and engines are performing and make improvements where necessary.

Torque Transducer Measurement Principle

The measurement principle of a torque transducer is all about detecting and measuring the twisting or rotational force applied to a rotating system.

Torque transducers work by using different methods, such as strain gauges, magnetoelasticity, or optical technology, to sense the amount of torque being applied.

For example, strain gauges work by measuring the electrical resistance of a metal strip that changes as it stretches or compresses in response to the applied torque.

The magnetoelastic type, on the other hand, uses a magnet and a magnetic field to sense changes in the shape of a metal element.

In each case, the torque transducer converts the twisting force into a measurable electrical signal, which can be analyzed and used to optimize the performance of the machine or engine.

Types of torque transducers

Type of Torque TransducerMeasurement PrincipleAdvantagesDisadvantages
Strain GaugeUses metal strip to change resistance when twistedAccurate and cost-effective; Good for low-torque applicationsCan be sensitive to temperature changes
MagnetoelasticUses magnetic field to measure torqueHighly accurate and durable; Good for high-torque applicationsCan be expensive
OpticalUses light to detect changes in material’s propertiesHighly accurate and non-contact; Good for high-speed applicationsCan be expensive and sensitive to vibration
Rotary TransformerUses two coils and a magnetic field to measure torqueHighly accurate and durable; Good for high-torque applicationsCan be expensive and sensitive to temperature changes
HybridCombines two or more principles for more precise measurementCan offer advantages of multiple typesCan be more complex and expensive

Static / Reaction Torque vs. Rotary Torque

When it comes to measuring torque, there are two main types: static/reaction torque and rotary torque.

Static torque refers to the twisting force applied to a non-moving object, such as a bolt or a nut.

Rotary torque refers to the twisting force applied to a rotating object, such as a motor or an engine.

Static torque measurement is important for applications where a component needs to be tightened to a specific torque value, such as in the automotive or aerospace industry.

Rotary torque measurement, on the other hand, is critical for assessing the performance of rotating machinery and ensuring its efficiency and longevity.

Both static and rotary torque measurement have their own unique challenges and require different types of torque transducers.

Understanding the differences between these two types of torque measurement is essential for selecting the appropriate torque transducer for a specific application.

This ratio is a crucial factor in selecting the right flow meter for your application, as it determines the meter’s ability to measure low and high flow rates with precision and accuracy.

Choosing a flow meter with a high turnover ratio can save you money and increase efficiency by eliminating the need for multiple flow meters or reducing maintenance and calibration costs. In this blog post, we will explore turnover ratio in flow meters, its importance, and how it impacts various industries.

RFQ Flow Meters

Definition of turndown ratio

So, what exactly is turndown ratio?

Well, it’s the measurement range of a flow meter from the highest to the lowest flow rate it can accurately measure. Essentially, it tells you how much the flow rate can be turned down or decreased while still maintaining accurate readings.

For example, a flow meter with a turndown ratio of 10:1 can accurately measure flow rates from 100 L/H down to 10 L/H.

This ratio is an important consideration when selecting a flow meter for your application, as it determines the meter’s versatility and ability to handle varying flow rates.

A higher turndown ratio means more flexibility and potentially cost savings, as you may not need multiple flow meters for different flow rates.

Why is Turndown Ratio important?

In flow measurement, the turndown ratio indicates the range of flow over which the flowmeter can measure with acceptable accuracy. It is also known as adjustable range. This is very important when selecting a flow meter technology for a specific application.

If the airflow to be measured is expected to vary between 100,000 cubic meters per day and 1,000,000 cubic meters per day. The turndown ratio for a specific application is then at least 10:1. Therefore, the meter requires at least a 10:1 turndown ratio.

Formula for calculating Turndown Ratio

The turndown ratio can be expressed as:
TR = Q(max)/Q(min)

TR = Regulation Ratio
Q(max) = maximum flow
Q (min) = minimum flow

Example calculation

If the gas to be measured varies between 100000 m3/day and 1000000 m3/day.
This particular application has TR = 10:1.
The TR of the required flow meter should be at least 10:1
If the flow meter has a maximum flow rate of 2000000 m3/day, then the required turndown ratio (TR) will be 20:1

Typical turndown ratios for various flowmeters

The examples here are for gas flow, but the same gauge type can be used for liquids, with similar turndown ratios.

Different types of flow meters have varying turnover ratios. Here are some common flow meters and their typical turnover ratios:

It’s important to note that these are general ranges and actual turnover ratios may vary depending on the specific model, size, and operating conditions. When selecting a flow meter, it’s crucial to consider the turnover ratio and ensure that it can accurately measure the flow rate needed for your application.

Demineralized Water Flow Measurement Case Study

Challenges in measuring demineralized water flow

Demineralized water: water that has been softened. That is to say, the water with part or all of the calcium and magnesium ions removed is the water that does not form scale after boiling. Boilers must use this water.

Demineralized water is super important in making medicine because it needs to be pure and clean. But measuring how much of this water is flowing can be tricky for a few reasons.

  1. The water doesn’t conduct electricity very well, which makes it hard to measure with regular equipment that relies on conductivity.
  2. It needs to be measured with really good equipment that won’t make it dirty.
  3. Air bubbles can form in the water, which messes up the measurements and might even break the equipment.
  4. Temperature changes can also mess up the measurements because the water gets thicker or thinner depending on how hot or cold it is.
  5. The equipment that measures the water flow needs to be taken care of and maintained regularly, which can be a big job, especially in large factories.

So, even though measuring the flow of demineralized water is important, it can be a challenge because of these issues.

How to Calculate Pressure Drop in a Pipe?

Posted on by

What is pressure drop in a pipe? Pressure drop is the decrease in pressure that occurs as fluids flow through pipes due to friction and other factors. When we choose and use various flowmeters, we may all hear the parameter of pressure loss or pressure drop.

It’s important to know how to calculate pressure drop in pipes, as it can help you troubleshoot issues, optimize your system’s performance. In this blog, we’ll show you how to calculate pressure drop in pipes and provide tips to minimize it in your system. Let’s dive in!

RFQ

5 Factors Affecting Pressure Drop

In industrial settings, pipes are often used to transport liquids, gases, and other materials over long distances. When fluids flow through pipes, they experience pressure drop due to various factors, which can affect the efficiency of the system and even cause equipment failure.

In an industrial pipe system, several factors contribute to pressure drop, including the flow rate, pipe diameter, pipe length, fluid properties (like density and viscosity). And the presence of fittings and valves. These factors must be carefully considered when designing or troubleshooting an industrial pipe system to ensure that it operates safely, efficiently, and reliably.

In this section, we’ll explore each of these factors in more detail and discuss their impact on pressure drop in industrial pipes.

Flow rate is one of the key factors that affects pressure drop in a pipe.

In simple terms, flow rate refers to the volume or mass of fluid that flows through a pipe per unit time. Typically measured in gallons per minute (GPM) or liters per second (L/s). The higher the flow rate, the greater the pressure drop in the pipe due to friction and other factors.

As the fluid flows through the pipe, it interacts with the walls of the pipe and experiences frictional resistance, which results in a loss of energy and pressure drop.

In addition to frictional resistance, high flow rates can also cause turbulence in the fluid, which further increases pressure drop. Turbulence occurs when the fluid flow becomes irregular and chaotic, causing eddies and vortices that can further reduce the fluid’s energy and increase pressure drop.

The National Institute of Standards and Technology (NIST) provides a comprehensive guide to fluid flow in pipes that includes equations and data for calculating pressure drop.

According to the NIST guide, the pressure drop in a pipe is directly proportional to the flow rate raised to the power of 1.75. This means that as the flow rate increases, the pressure drop increases at a faster rate.

The NIST guide is available on the official website of the U.S. Department of Commerce.

The diameter of a pipe is a crucial factor that affects pressure loss in pipelines. Generally, smaller pipes have higher pressure losses than larger pipes.

This is due to the relatively greater surface area of smaller pipes, which results in higher frictional losses and turbulence in the fluid.

Additionally, smaller pipes are more prone to blockages or obstructions, which can further increase pressure loss.

To illustrate the impact of pipe diameter on pressure loss, researchers often use the Darcy-Weisbach equation, which relates pressure loss to pipe diameter, fluid density, fluid velocity, and other variables.

According to this equation, pressure loss is proportional to the length of the pipe, the fluid viscosity, and the square of the fluid velocity. But inversely proportional to the diameter of the pipe raised to the power of 5.

For example, if the diameter of a pipe is doubled, the pressure loss is reduced by a factor of 32. This demonstrates the importance of selecting the appropriate pipe diameter for a given system to minimize pressure loss and optimize system performance.

The length of a pipe is another crucial factor that affects pressure loss in pipelines.

Generally, longer pipes have higher pressure losses than shorter pipes. This is due to the relatively greater surface area and more frictional losses in longer pipes.

Additionally, longer pipes are more prone to blockages or obstructions, which can further increase pressure loss.

The Darcy-Weisbach equation, which relates pressure loss to pipe length, fluid density, fluid velocity, and other variables. According to this equation, pressure loss is proportional to the length of the pipe, the fluid viscosity, and the square of the fluid velocity, but inversely proportional to the diameter of the pipe raised to the power of 5.

For example, if the length of a pipe is doubled, the pressure loss is also doubled. This demonstrates the importance of minimizing the length of pipelines and selecting the appropriate pipe diameter for a given system to minimize pressure loss and optimize system performance.

The fluid properties, including density and viscosity, are important factors affecting pipeline pressure loss. As the fluid density and viscosity increase, the pressure loss in the pipe also increases.

This is due to the increased friction between the fluid and the pipe walls, resulting in a greater loss of energy as the fluid flows through the pipe.

According to a study published in the Journal of Energy, the effect of fluid density on pipeline pressure loss can be significant. Increasing the fluid density from 1 kg/m³ to 1000 kg/m³ resulted in a 30% increase in pressure drop.

Another study published in the Journal of Petroleum Science and Engineering showed that the effect of fluid viscosity on pipeline pressure loss is even more significant. Increasing the fluid viscosity from 1 cP to 100 cP resulted in a 270% increase in pressure drop.

In addition to pipe diameter, length, and fluid properties, the fittings and valves used in a pipeline also affect the pressure loss. Fittings and valves cause additional turbulence in the fluid flow, leading to increased friction and pressure loss.

According to a report published by the National Institute of Standards and Technology (NIST), the pressure loss in a pipeline due to fittings and valves can range from 10% to over 50% of the total pressure drop, depending on the type and number of fittings and valves used.

Calculation of Pressure Drop

Calculating pressure drop in a pipeline involves several steps, including:

  • Determine the flow rate of the fluid in the pipeline.
  • Determine the properties of the fluid, such as density and viscosity.
  • Measure the pipe length, diameter, and roughness.
  • Determine the number and type of fittings and valves in the pipeline.
  • Select the appropriate pressure drop equation based on the specific pipeline conditions and design.
  • Calculate the Reynolds number to determine if the flow is laminar or turbulent.
  • Use the selected pressure drop equation to calculate the pressure drop.
  • Compare the calculated pressure drop with the maximum allowable pressure drop to ensure that the pipeline operates safely.

It’s important to note that pressure drop calculations may need to be repeated several times to ensure that the pipeline design meets the required pressure and flow rate specifications. It’s also important to ensure that accurate and up-to-date data is used in the calculation to ensure the safety and efficiency of the pipeline.

Pressure Drop Equations

Pressure drop equations are mathematical formulas that engineers and designers use to calculate the pressure loss in a pipeline. There are many different equations, but three of the most common are Bernoulli’s equation, the Darcy-Weisbach equation, and the Hazen-Williams equation.

  • Bernoulli’s equation
  • Darcy-Weisbach equation
  • Hazen-Williams equation

For a detailed introduction to the equation, please refer to the professional academic website. There are detailed discussions. We will not repeat them here.

Online Pressure Drop Calculators and Software

Online pressure drop calculators and software have made it easier than ever to calculate the pressure drop in a pipeline. These tools provide users with an easy and efficient way to input pipeline data and receive accurate pressure drop calculations.

Online calculators typically require the user to input pipeline data such as flow rate, pipe diameter, length, fluid density and viscosity, and fittings and valve information. The software then uses algorithms and equations to provide an estimate of the pressure drop in the pipeline.

These tools are particularly useful for engineers, technicians, and operators who need to quickly and accurately calculate pressure drops for a wide range of pipeline applications.

For example: Pressure Drop Online-Calculator

Flow Meter Pressure Drop

Flow Meter Pressure Drop, also known as Pressure loss, is one of the key indicators of flow meters.

Flow Meter Pressure Drop is used to describe the pressure difference (P1-P2) before and after the flow meter input (P1) and output (P2). It is also the minimum pressure difference to ensure the normal operation of the flowmeter. It is one of the basic parameters of the flowmeter.

The pressure loss of the flowmeter generally increases with the increase of the flow rate. Also affected by the solution. For example, the pressure loss of flowmeters based on ultrasonic flowmeters and MEMS (micro-electromechanical systems) is much smaller than that of vortex flowmeters and differential pressure flowmeters.

What Is Capacitive Level Sensor?

Posted on by

What is a Capacitive Level Sensor? Simply put, it’s a device used to accurately measure the level of materials in various industries. Unlike other types of sensors, capacitive level sensors use electrical properties to detect changes in the level of materials, making them non-contact and highly accurate.

In this article, we’ll dive into the world of capacitive level sensors, discussing how they work, where they’re used, their advantages and limitations, and what factors to consider when selecting one. If you’re new to capacitive level sensors, or just looking to learn more, this guide is the perfect place to start.

The purpose of a capacitive level sensor is to accurately and reliably measure the level of materials in various industrial applications.

Capacitive level sensor can measure the level of highly corrosive medium, high temperature medium and sealed container, regardless of the viscosity, density and working pressure of the medium.

Let’s first get to know the working principle of the capacitive level sensor.

capacitive level Measurement Principle

Have you ever wondered how we can measure the level of material in a tank? Well, that’s where the magic of capacitance level measurement comes in!

Think of a capacitor like two metal plates, with a thin layer of insulation in between. When the plates are close together, they can hold more electrical charge. In this measurement technique, the probe acts as one plate and the tank wall as the other. When the tank is empty, there’s plenty of space between the two plates, meaning they can hold very little charge. But as the material fills the tank, the plates move closer together and are able to hold more charge.

So, by measuring the electrical charge between the probe and the tank wall, we can determine just how full the tank is! It’s like a secret code between the sensor and the material in the tank, giving us the scoop on its contents.

Capacitance level measurement is a straightforward, dependable, and non-invasive way to keep track of what’s inside a tank. So the next time you’re curious about how much material is left, just remember the wonder of capacitance level measurement!

These examples demonstrate the wide range of industries that use capacitive level sensors and the variety of applications for which they are used.

Advantages and limitations of capacitive level sensors

The advantages of using capacitive level sensors:

  • Simple structure without any movable or elastic components. The result is high reliability and minimal maintenance. Under normal circumstances, there is no need to carry out routine major, medium and minor repairs.
  • A variety of signal output, convenient for different system configurations.
  • It is suitable for liquid level measurement of high temperature and high pressure containers. And the measured value is not affected by the temperature, specific gravity of the measured liquid, the shape and pressure of the container.
  • It is especially suitable for the measurement of strong corrosive liquids such as acids and alkalis.
  • There are perfect over-current, over-voltage, power polarity protection.

The limitations of capacitive level sensors

  • Full working condition measurement cannot be implemented. There is “false water level” measurement, and it takes a long time to establish a stable differential pressure condition under unstable operating conditions such as boiler start, stop, emptying, continuous row, accident, etc.
  • Under stable working conditions, due to structural limitations. It cannot solve the compensation problem of system measurement error caused by water side insulation.
  • Under accident conditions such as boiler shortage and full water. Systematic measurement errors that are too large can have serious consequences.
  • The construction scale is large and there are winter insulation problems.
  • The measurement time lag is long. It cannot respond to boiler water level changes immediately. Poor quality of measurement signal conditioning.
  • Due to the heat release of the condensing cylinder, the cost of use is relatively high.

Factors to consider when selecting a capacitive level sensor

After so many details. You may want to know, how should I choose a suitable capacitive level sensor? By our years of production experience. It is recommended that you consider the following points.

  1. Material compatibility: Material compatibility is very important because different materials can affect the accuracy of sensor readings or even damage the sensor. For example, materials such as PTFE or stainless steel can be used.
  2. Temperature range: Choosing a sensor that can work within the expected temperature range will ensure accurate readings. For example, common temperature ranges include 80℃, 100℃, high temperature 250℃, low temperature -196℃, etc.
  3. Measuring range: For small measuring ranges, a rod-type probe can be selected. For larger measuring ranges, such as 8 meters or 10 meters, a cable-type probe can be selected.
  4. Installation options: Installation size and location.
  5. Sensitivity: We generally provide a measurement accuracy of 0.5 or 1 level.
  6. Output type: For example, 4-20mA, 0-5V signal output. Or RS485, RS232 communication, etc.
  7. Pressure range: Common tank pressures include -0.1 MPa to 5 MPa. Some high-pressure sensors can be customized to withstand pressures up to 32 MPa.
  8. Special requirements: Such as explosion-proof, hygienic, and other requirements.

By considering these factors, you can ensure that you select a capacitive level sensor that meets the specific requirements of your application.
