Product Description
,Product Summary
Ultrasonic water meter is used to accurately measure the flow rate. The product has the characteristics of beautiful appearance, convenient installation, accurate measurement, stable operation, strong anti-pollution and anti-corrosion capability, long service life, small pressure loss, economy and practicality, etc. It is suitable for flow metering and charging of domestic water, central air conditioning system water, etc.
Implementation standard: GB/T 778 Measurement of water flow in closed full pipeline Drinking cold water meter and hot water meter JJG 162-2009 Cold water meter
,Working Principle
Ultrasonic water meter adopts the principle of ultrasonic wave. It is a kind of water meter that further calculates the flow rate of water by analyzing and processing the time difference caused by the change of speed when ultrasonic sound beam propagates downstream and countercurrent in water.
