1.Product Introduction of Handheld Ultrasonic Flow Meter

Handheld Ultrasonic Flow Meter can measure the flow of conductive or non-conductive, corrosive or non-corrosive liquids, with flexible operation and convenient portability.The Handheld Ultrasonic Flow Meter uses a low-voltage, multi-pulse transmitting circuit, which greatly improves the measurement accuracy, service life and reliability; the dual-balanced signal differential transmitting and receiving circuit can effectively resist interference from strong interference sources such as frequency converters, TV towers, high-voltage lines, etc.; the built-in rechargeable NiMH battery can work continuously for more than 12 hours; the optimized intelligent signal adaptive processing does not require any circuit adjustment by the user.

Ultrasonic flowmeters are largely made of world-renowned semiconductor manufacturers, such as Philips, Maxim, Ti, Winbond and Xilinx, etc. The advanced circuit design, the selection of the latest devices, the excellent hardware design and the user-friendly software design in Chinese and English make ultrasonic flowmeters well received by users.

2. Features of Handheld Ultrasonic Flow Meter

* Large LCD display

* RS-232 standard data interface

3. Working Principle of Handheld Ultrasonic Flow Meter

When the ultrasonic beam propagates in the 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 the two sensors to transmit and receive the sound waves is exactly the same (the only technology that can actually measure zero flow). When the liquid flows, the sound wave transmission time in the upstream direction is greater than the sound wave transmission time in the downstream direction.
