Large Diameter Ultrasonic Prepaid Water Meter Wide Selection of Wholesale

The ultrasonic water meter is a new type of water meter that detects the time difference caused by the speed change when the ultrasonic sound beam propagates upstream and downstream in the water, analyzes and processes the water flow rate, and further accumulates 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.
