The ultrasonic flowmeter is based on the principle of "velocity difference method" to measure the liquid flow in the circular tube. It adopts advanced multi-pulse technology, signal digital processing technology and error correction technology, which makes the flow meter more suitable for the environment of the industrial site, and the measurement is more convenient, economical and accurate. The products have reached the advanced level at home and abroad, and can be widely used in petroleum, chemical, metallurgy, electric power, water supply and drainage and other fields.



There are many manufacturers of ultrasonic flowmeters on the market, and some of them have rich experience. High measurement accuracy, full Chinese display, flexible operation and other features, cost-effective. Once the product is launched, it is favored by customers at home and abroad, and has been exported to Japan, South Korea, Europe, America and the Middle East, and has been well received by customers at home and abroad.

According to the principle of signal detection, ultrasonic flowmeter can be divided into propagation velocity difference method (direct time difference method, time difference method, phase difference method and frequency difference method), beam shifting method, Doppler method, cross-correlation method, spatial filtering method and noise law.



Like electromagnetic flowmeters, ultrasonic flowmeters are unobstructed flowmeters because there is no obstruction in the flow channel of the instrument. They are a type of flowmeter suitable for solving difficult problems in flow measurement, especially in large-diameter flow measurement. It is one of the rapidly developing class of flowmeters.

The joint test ultrasonic flowmeter is a non-contact instrument, which can measure the flow of medium with large diameter and can also be used for the measurement of medium that is difficult to contact and observe. Its measurement accuracy is very high, and it is hardly interfered by various parameters of the measured medium.
