产品概述：

Ultrasonic water meter
Ultrasonic water meter is a new type of water meter, which can detect the time difference caused by the change of velocity when the ultrasonic beam propagates along and against the current in the water, analyze the flow rate of the treated water, and further calculate the flow rate of the treated water.
characteristic:
1. Low initial velocity, wide range ratio, high measurement accuracy and stable operation.
2. There are no moving parts inside, no current blocking elements, not affected by impurities in water, and long service life.
3. The output communication function is complete, meeting the requirements of all kinds of communication and wireless networking.
4. It has excellent small flow detection ability, which can solve the problems of many traditional water meters, and is more suitable for use
5. It is more suitable for the saving and rational use of water resources, and has a broad market and use prospects.
