FUW870 Sandwich Ultrasonic Water Meter

FUW870 ultrasonic water meter is a new type of water meter that can further calculate the water flow by detecting the time difference caused by the speed change when the ultrasonic sound beam propagates upstream and downstream in the water, and analyzes and processes the water flow rate.
Features: low initial flow rate, wide range ratio, high measurement accuracy and stable operation.
There are no moving parts inside, no blocking elements, and it is not affected by impurities in the water, and has a long service life. The output communication function is complete, meeting various communication and wireless networking requirements.
It has excellent small flow detection ability, can solve many problems of traditional water meters, is more suitable for gradient charging of water fee, more suitable for saving and rational utilization of water resources, and has broad market and application prospects.
