Ultrasonic type flow meter
Ultrasonic flowmeter, as a volumetric flowmeter, belongs to the category of non-intrusive flow sensors and is widely used in industrial and civil fields. Its working principle is to use acoustic vibration to measure the flow of liquid. It has the characteristics of high precision, fast response and easy use. Among ultrasonic liquid flow meters, there are two main types, namely Doppler flow meters and transit time ultrasonic flowmeters.
Doppler flowmeters calculate flow velocity by measuring the velocity of suspended particles in a fluid, similar to Doppler radar. When a sound wave encounters a moving object, its frequency changes. Based on this frequency change, the speed of the fluid can be deduced. Doppler flow meters are suitable for media containing particles in liquids, such as sewage, wastewater, etc., and can measure flow rates stably and accurately.
The transit time ultrasonic flow meter calculates the flow rate by measuring the time it takes for sound waves to travel through the liquid. The principle is to use the relationship between the speed of sound waves propagating in fluids and the flow rate, and determine the flow rate by measuring the time difference between the sending and receiving of sound waves. The transit time flow meter is suitable for various clean liquid media, such as water, oil, etc., with wide applicability and high accuracy.

•Improving manufacturing quality through reliable, accurate measurements
•Increased productivity due to shorter installation times and no downtime
•Maintenance is reduced since the sensor is not in direct contact with the fluid being measured
This technology has a number of unique technical features, including the following aspects:
•The technology does not require pipe cutting, which means there is no need to interrupt production or process flow during installation, thus avoiding production losses caused by production line shutdowns.
•This technology does not produce a pressure drop during the measurement process, maintains the normal operating status of the pipeline system, and does not have any negative impact on fluid transmission.
•The sensor of this technology does not come into direct contact with the liquid being measured, achieving high-precision flow measurement through non-contact measurement technology while avoiding possible contamination problems caused by contact.
•Since the sensor does not come into contact with liquid, the risk of leakage is eliminated, greatly improving the safety and reliability of the equipment.
How does an ultrasonic liquid flow meter work?
The working principle of ultrasonic liquid flow meters is based on the time difference between the propagation of ultrasonic waves in the fluid. This type of flow meter usually consists of two high-frequency transducers mounted on the outside of the pipe. Ultrasonic waves propagate through the pipe wall over the diagonal cross-sectional area of the pipe into the flowing liquid stream, from one transducer to another. In the case of fluid flow, the ultrasonic pulse "carries" in the direction of flow, while the reflected signal beam "slows down" on the contrary. As a result, the time required for signal transmission from one ultrasonic sensor to another varies. The flowmeter operates by alternating the transmission and reception of sound waves at modulated frequencies. The difference in the propagation time of the sound wave is directly proportional to the measured value of the flow rate and fluid flow. Since the acoustic properties of each liquid are different, it is essential to set the parameters of the ultrasonic flow meter appropriately to ensure a highly accurate measurement.

There are three installation methods for clamp-on ultrasonic flow meters. These three methods are called V method, Z method, and N method respectively.
Generally, when the small pipe diameter is 100~300mm (4"~12"), the V method can be selected first; When the V method cannot detect the signal or the signal quality is poor, the Z method is used; When the pipe diameter is more than 300mm (12") or the cast iron pipe is measured, the Z method should be preferred.
The N method is a less commonly used method and is suitable for pipes with diameters up to 50 mm (2").
Precautions for installation of ultrasonic type flow meter sensor
1. The input pipe parameters must be correct, otherwise it will cause the sensor to be installed incorrectly and not work properly.
2. When installing the clamp-on sensor, use enough couplant to stick it to the pipe wall, and slowly move the sensor near the installation point until the strongest signal and maximum signal quality value are received.
3. Confirm whether the installation distance is in accordance with the sensor installation distance given in the manual.
4. If the signal strength is always 0.00, it means that the flowmeter has not received the ultrasonic signal, and it should be checked whether the parameters related to the pipeline are entered correctly, whether the pipeline is too old, whether its lining is too thick, whether there is no fluid in the pipeline, whether the installation is too close to the valve elbow, whether there are too many bubbles in the fluid, etc.
5. It should be avoided to install and use the flowmeter in the environment with large electromagnetic interference, so as not to cause the accepted signal strength to be too low or fluctuate, which will affect the normal operation of the flowmeter.
6. At the end of installation, the instrument should be powered back on, and the parameters and display results should be checked to see if they are correct.

Generally, when the pipe diameter is 100-~300mm (4"~12"), the V method can be used first; when the V method cannot detect the signal or the signal quality is poor, the Z method can be used: the pipe diameter is above 300mm (12") or the measurement When casting iron pipes, the Z method should be preferred. The N method is a less commonly used method and is suitable for pipes with a diameter of less than 50mm (2").
Q: What material is used for ultrasonic flow meter pipe?
A: Ultrasonic flow meters are suitable for a variety of pipe materials, such as carbon steel, stainless steel, copper, aluminum, iron and plastic. However, it must be ensured that the material of the pipe is strong and there must be no obvious wear, corrosion, or wave deformation that would affect the propagation of ultrasonic waves.
Q: What is a non contact liquid flow measurement?
A: A non-contact flow meter utilizes ultrasonic technology to measure flow rate at critical points of various biotech processes. Ultrasonic technology enables non-contact detection of flow, independent of liquid composition (turbidity, charge, temperature etc.).
Q: The pipe is new, the material is very good, and it meets the installation conditions, but the signal cannot be received?
A: Check whether the pipeline parameters are set correctly, the installation method is correct, the wiring is in good contact, and the coupling agent is fully applied.
Whether the pipeline is full, whether the sensor is installed according to the installation distance shown in the general diagram of the instruction manual, and whether the sensor is installed in the wrong direction.
Q: The pipeline is old and the inner wall of the pipeline is severely scaled. No signal is received during measurement or the signal is too weak. How to solve the problem?
A: Check whether there is fluid in the pipe and it is full;
The Z method should be used to install the sensor (if the pipe is too close to the wall, the sensor can be installed on an inclined pipe diameter instead of a horizontal pipe diameter);
Carefully select the dense part of the pipe and polish it sufficiently, apply sufficient coupling agent and install the sensor;
Carefully and slowly move each sensor near the installation point to find the maximum signal point to prevent the installation point that can receive a stronger signal from being missed due to scaling on the inner wall of the pipe or local deformation of the pipe causing the ultrasonic beam to reflect out of the expected area. :
For metal pipes with serious inner wall scaling, you can use hitting methods to make the scaled parts fall off or crack (note: this method sometimes creates gaps between the scaling and the inner wall, which is detrimental to the propagation of ultrasonic waves).
Q: Why is there flow in the pipeline, but the machine still displays the normal working status of the system, and the instantaneous flow rate displayed by the machine is zero?
A: Check if the "static zero setting" was used in the presence of fluid, if so, use the menu to restore the original factory zero setting.
