1.Product Introduction of Handheld Ultrasonic Flow Meter
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.

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.

The Visibility Detector is mainly a forward-scattering visibility meter, which is an important instrument for measuring visibility.The transmitter and the receiver are kept at a certain distance and at a certain angle. The receiver only receives the forward-scattering light of the atmosphere. The tr...
Visibility can be measured by visual observation, relying on manual inspection to estimate the visibility distance based on whether a certain reference object is visible. This method is simple and intuitive, but it is highly subjective and has poor standardization and objectivity.We recommend using...
When the fog is thick, it is particularly difficult to navigate ships in places like the Huangpu River where the waterway is narrow and the navigation conditions are complex. Due to the heavy fog, the pilots can hardly see the ships in the distance and the objects on the shore. At this time, relying...
