Pipe Flow Meter Basics

Understanding Pipe Flow

When it comes to pipe flow, it’s essential to know that not all fluid flow is created equal. There are two main types of flow you’ll come across: laminar flow and turbulent flow. Let’s break them down in a way that’s easy to understand.

Laminar flow is the smooth, orderly flow of fluid in a pipe. Picture a peaceful river, where the water glides effortlessly along. In laminar flow, the fluid’s layers slide past each other without much mixing, resulting in a low flow resistance.

Turbulent flow, on the other hand, is a bit more chaotic. Imagine a raging river, with water swirling and splashing all over the place. In turbulent flow, the fluid particles are constantly colliding and mixing, causing more resistance and making it harder to predict the flow’s behavior.

Learn more about laminar and turbulent flow from Wikipedia.

Now that we’ve covered the two main types of flow, let’s explore some factors that can affect pipe flow:

Pipe diameter: The size of the pipe has a direct impact on the flow. A larger diameter generally leads to lower flow resistance and higher flow rates.
Fluid viscosity: Viscosity is a measure of how thick a fluid is. The thicker (or more viscous) the fluid, the harder it is for it to flow through a pipe.
Pipe roughness: The smoother a pipe’s interior surface, the less resistance there is for the fluid to flow. Rough pipes can lead to more turbulent flow and increased energy loss.
Flow velocity: The speed at which the fluid is moving in the pipe affects the type of flow as well. Higher velocities are more likely to cause turbulent flow, while lower velocities favor laminar flow.

By understanding these basic concepts of pipe flow, you’ll be well-equipped to tackle any flow-related challenge!

Ultrasonic Depth Sensor vs Ultrasonic Level Sensor

Posted on March 8, 2023 by KimGuo11

What is the difference between Ultrasonic Depth Sensor and Ultrasonic Level Sensor?

Recently, many customers have questioned whether Ultrasonic Depth Sensor and Ultrasonic Level Sensor have the same function? Of course not. Both Ultrasonic Depth Sensor and level sensor are commonly used in water level measurement. Such as water treatment plants, or water tanks, etc. But there are still subtle differences.

The difference between Ultrasonic Depth Sensor and Ultrasonic Level Sensor

Next, we list the differences between Ultrasonic Depth Sensor and Ultrasonic Level Sensor.

1. The working environment is different

The probe and host of Ultrasonic Level Sensor are placed in the air.

Ultrasonic Depth Sensor works in water. The probe of the Depth Sensor needs to be placed in the water to measure the depth of the water.

2. The measurement distance is different

Ultrasonic Level Sensor ranges in the air between 0-70 meters.

The Ultrasonic Depth Sensor can measure distances of several kilometers in water.

3. The working principle is different

The working principle of the Ultrasonic Level Meter is that the ultrasonic probe part emits ultrasonic waves, which are then reflected by the liquid surface, and then received by the probe part. The distance from the probe to the liquid (object) surface is proportional to the elapsed time of the ultrasonic waves.

The working principle of the Ultrasonic Depth Sensor is designed based on the principle that ultrasonic energy propagates in a straight line at a uniform speed in a homogeneous medium, and is reflected when it encounters different medium surfaces.

Ultrasonic Depth Sensor uses water as the ultrasonic medium. When measuring depth, place the ultrasonic probe at a certain position underwater. The depth from the probe to the bottom of the water can be calculated according to the propagation speed of ultrasonic waves in water and the time interval between sending out and receiving ultrasonic signals.

More About Ultrasonic Level Measurement

Advantages of ultrasonic level sensor

Ultrasonic level sensor can achieve non-contact measurement.
Ultrasonic level sensor can measure a large range. And liquid, block, powder level can be measured.
The ultrasonic level sensor can measure continuously at fixed points, and can conveniently provide measurement signals for telemetry and remote control.
The installation of ultrasonic level sensor is simple and convenient, and does not require safety protection.

Disadvantages of ultrasonic level sensor

Ultrasonic level sensor measurement will have a blind area. It is necessary to avoid the blind area during installation.
In the case of foam, since the sound wave cannot penetrate the foam, the sound wave will be reflected on the foam. In this way, the measurement will have a large deviation from the actual liquid level.
In a container with an agitator, it will be affected by the agitator, causing false reflection echoes and inaccurate measurements.
The temperature of the measuring medium is also affected. Especially in a closed container.

4-20mA signal output is the normal configuration of ultrasonic level meter. Two-wire and four-wire 4-20mA signal output can be selected.

The power supply (DC24V) and signal output (DC4-20mA) of the two-wire ultrasonic level meter share a circuit, which is a standard transmitter form. The disadvantage is that the transmission power is weak. Not suitable for liquid level measurement with large fluctuations. When the liquid level has greater volatilization, the measurement effect is also unsatisfactory.

The four-wire ultrasonic level meter uses two wires for power supply 220VAC and signal output 4-20mADC. The negative stage of the power supply and the negative stage of the signal are separated. Its advantage is that the transmission power is relatively large. Suitable for on-site installation, independent power supply.

Ultrasonic level sensor is often used to measure the liquid level of water storage tanks. Because the ultrasonic level sensor is easy to install and low in cost.

More about: Water tank level sensor system

When it is necessary to measure the liquid level of a diesel storage tank, an ultrasonic level meter can be used.
Can be divided into the following two situations.

If your tank has a hole in the top, or can. Then choose explosion-proof ultrasonic level meter. The installation is simple, the measurement is stable, and the cost is not high.
If your tank cannot be opened. Then you can choose an externally attached ultrasonic level meter. No tank opening is required. The sensor is attached to the bottom and sides of the tank. But the cost will be higher.

Ultrasonic level sensor for solids is also called solid material level measurement. Some people understand that as long as it is a solid, it can be measured, but it is wrong. It has prerequisites for its measurement.

What material levels can the ultrasonic level sensor measure?

Powdered solid:
If it is measured with a general ultrasonic level gauge, it is difficult to measure it. Take the measurement of flour as an example. An ultrasonic level meter with a range of 10 meters can only measure a distance of about 2 meters, and it will not be able to measure it any further. Substances such as cement powder, soybean powder, wood residue, and fly ash are not easy to measure.
The powder solids that can be measured include: yellow sand, iron powder, stone powder and other substances with a density greater than 3000 kg/m3.
Granular solid:
The particle diameter is required to be greater than 3mm, and the density is greater than 1000 kg/m3.
For example: ABS particles, stones, wheat, etc. Under the premise of no dust, the selected ultrasonic level meter should be 3 times larger than the actual measuring range.
Lumpy solid:
Such as: coal, ore, etc., most of the massive solids can be measured. The selected level measurement range should also be 3 times larger than the actual range.

If you want to measure solid material level by ultrasonic level meter, please communicate with the manufacturer first, whether the medium you want to measure can be measured by ultrasonic. Remember not to buy blindly.

Different Types of Flowmeters – Technical and Application Analysis

Posted on February 27, 2023 by KimGuo11

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?

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

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 Flowmeter	Principle of Operation	Advantages	Disadvantages
Piston Flowmeters	Use a piston moving inside a chamber to measure fluid flow.	Highly accurate; Suitable for low to high viscosity fluids	Not suitable for measuring fluids with suspended solids
Oval Gear Flowmeters	Two oval gears rotating in opposite directions	Highly accurate; Suitable for low to medium viscosity fluids	Affected by fluid temperature and viscosity changes
Nutating Disc Flowmeters	A disc that “nutates” or wobbles to trap and measure fluid flow	Highly accurate; Suitable for low viscosity fluids	Affected by fluid temperature changes
Rotary Vane Flowmeters	A rotor with vanes that rotate inside a chamber	Highly accurate; Suitable for low to high viscosity fluids	Not suitable for measuring fluids with suspended solids

More details about: PD Flow Meters Selection and Application | Oil-Liquid

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 Flowmeter	Principle of Operation	Advantages	Disadvantages
Turbine Flowmeters	Turbine rotor spins as fluid flows through it	Highly accurate; Suitable for clean fluids with low to medium viscosity	Affected by changes in fluid density, temperature, and viscosity
Electromagnetic Flowmeters	Faraday’s Law to measure voltage generated by fluid flow through a magnetic field	Highly accurate; Suitable for measuring conductive fluids such as water and acids	Not suitable for measuring non-conductive fluids
Vortex Flowmeters	Measure fluid flow using the principle of the Karman vortex street	Highly accurate; Suitable for clean fluids with low to medium viscosity	Can be affected by changes in fluid density
Ultrasonic Flowmeters	Use ultrasonic sensors to measure the time it takes for an ultrasonic signal to travel between two points in the fluid flow	Highly accurate; Suitable for measuring fluids of different viscosities, densities, and conductivities	Often 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 Flowmeter	Principle of Operation	Advantages	Disadvantages
Flumes	Specially designed constriction	High accuracy, low cost, ease of installation	Affected by changes in channel shape, require certain amount of head loss
Weirs	Sharp-crested structure	High accuracy, low cost, ease of installation	Affected by changes in channel shape, require certain amount of head loss
Area-Velocity Meters	Measure velocity at multiple points and combine with cross-sectional area	High accuracy, measure flow rates in irregular channels, measure both forward and reverse flow	More complex and costly than other open channel flow meters
Ultrasonic Doppler Meters	Use sound waves to measure velocity	High accuracy, measure flow rates in irregular channels, measure both forward and reverse flow	Affected by changes in liquid’s acoustic properties, may require calib

How to select a flow meter?

Here are some of the key parameters that can affect the selection of a flowmeter for a particular application:

Fluid type and properties, such as viscosity, density, and corrosiveness
Flow rate range and required accuracy
Operating conditions, such as temperature, pressure, and fluid velocity
Installation requirements, such as the orientation and size of the pipe
Availability of power or signal inputs for the flowmeter
Environmental conditions, such as the presence of hazardous or explosive materials
Required maintenance and calibration intervals
Compatibility with existing control systems or instrumentation
Cost and budget considerations.

Here are some recommendations for selecting flowmeters for specific fluid applications:

What Is a Torque Transducer? How to Choose?

Posted on February 26, 2023 by KimGuo11

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 Transducer	Measurement Principle	Advantages	Disadvantages
Strain Gauge	Uses metal strip to change resistance when twisted	Accurate and cost-effective; Good for low-torque applications	Can be sensitive to temperature changes
Magnetoelastic	Uses magnetic field to measure torque	Highly accurate and durable; Good for high-torque applications	Can be expensive
Optical	Uses light to detect changes in material’s properties	Highly accurate and non-contact; Good for high-speed applications	Can be expensive and sensitive to vibration
Rotary Transformer	Uses two coils and a magnetic field to measure torque	Highly accurate and durable; Good for high-torque applications	Can be expensive and sensitive to temperature changes
Hybrid	Combines two or more principles for more precise measurement	Can offer advantages of multiple types	Can 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.

River water level monitoring system

The river water level monitoring system is mainly composed of radar water level meter or ultrasonic water level meter, monitoring host and server.

River water level meters are usually installed on the side of river bridges by wall-mounting. Can collect river water level data in real time. Report the data to the monitoring terminal through serial communication.

After the monitoring host receives the data reported by the detector, it communicates via wireless 4G/2G/NB-lot. Report the water level data to the background server in real time. Supervisors can keep abreast of the current river conditions through the business terminal.

The monitoring host usually uses a polymer lithium battery pack. Cooperating with the independent photovoltaic power supply system, it can provide stable power supply for the monitoring host for a long time.

Common communication methods for data transmission include 3G/4G, GSM/GPRS, etc. At present, the 4G mobile signals in the flood-prone areas of most cities have basically been covered. The good signal rate is very high. Have good communication conditions. Therefore, the water monitoring equipment can use 4G as the main channel to upload the monitoring data to the center. And it is backward compatible with 3G/GPRS as a backup channel.
