1.Introduction to Handheld Ultrasonic Flow Meter Products
Handheld Ultrasonic Flow Meter provides non-invasive flow measurement for monitoring liquids in pipelines such as water, wastewater, oil, glycol, etc.Handheld Ultrasonic Flow Meter adopts low voltage and multi-pulse transmitting circuits, which greatly improves measurement accuracy, service life and reliability; dual-balanced signal differential transmitting and receiving circuits can effectively resist interference from strong interference sources such as inverters, TV towers, and high-voltage lines; built-in rechargeable nickel-hydrogen battery, which can work continuously for more than 12 hours; optimized intelligent signal adaptive processing, and users do not need any circuit adjustments.
Ultrasonic flowmeters are widely used by 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 friendly software design in Chinese and English user interfaces have made the ultrasonic flowmeter well received by users.
2.Features of Handheld Ultrasonic Flow Meter
* Large screen LCD display
* Contactless measurement
* Built-in data logger
* Built-in rechargeable battery
*High precision measurement
* Large measurement range
* Small size and light weight
* RS-232 standard data interface
3.Working principle of Handheld Ultrasonic Flow Meter
When an ultrasonic beam propagates in the liquid, the flow of the liquid will cause a slight change in the propagation time, and the change in its 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 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 countercurrent direction is greater than the sound wave transmission time in the downstream direction.
