1. Product introduction of handheld ultrasonic flow meter

Handheld ultrasonic flow meter, also known as ultrasonic liquid flow meter, is suitable for online calibration and patrol measurement of liquid flow in various industrial sites. It uses external clamp-on sensing to measure liquid flow and has a variety of optional functions. and accessories to meet your various liquid flow measurement requirements. The handheld ultrasonic flowmeter adopts a low-voltage, multi-pulse transmitting circuit, which greatly improves the measurement accuracy, service life and reliability; the double-balanced signal differential transmitting and receiving circuit can effectively resist interference from strong interference sources such as frequency converters, TV towers, and high-voltage lines. ; Built-in rechargeable Ni-MH battery, can work continuously for more than 12 hours; Optimized intelligent signal adaptive processing, users do not need any circuit adjustment.

Ultrasonic flowmeters use a large number of world-renowned semiconductor manufacturers, such as: Philips, Maxim, Ti, Winbond and Xilinx. Advanced circuit design, the selection of the latest devices, excellent hardware design, and user-friendly software design in Chinese and English have made the ultrasonic flowmeter highly praised by users.

3. Working principle of handheld ultrasonic flow meter

When an ultrasonic beam propagates in a liquid, the flow of the liquid will cause a slight change in the propagation time, and the change in the propagation time is proportional to the flow rate of the liquid. At zero flow, the time required for both sensors to emit and receive sound waves is exactly the same (the only technology that can actually measure zero flow). When liquid flows, the sound wave transmission time in the countercurrent direction is greater than the sound wave transmission time in the downstream direction.
