Product Overview
Ultrasonic Smart Water Meter is a new type of water meter that analyzes and processes the flow rate of water by detecting the time difference generated by the change of speed when the ultrasonic sound beam propagates in the water in downstream and countercurrent, and then further calculates the flow rate of water. The starting flow rate is low, the range ratio is wide, the measuring accuracy is high and the work is stable. No internal moving parts, no flow blocking elements, not affected by impurities in the water, long service life. The output communication function is complete to meet all kinds of communication and wireless networking requirements. With excellent small flow detection ability, it can solve the problems of many traditional water meters, and is more suitable for water gradient charging, more suitable for saving and rational use of water resources, and has a broad market and use prospects.
