Product Description

bulk ultrasonic water meter

The ultrasonic water meter is a metering instrument that continuously measures, records, and displays the volume of water flowing through the sensor using the ultrasonic time difference method. Please read this manual carefully before use, to use it to the best advantage and avoid unnecessary loss.

working principle

Ultrasonic water meter is a new type of water meter that can detect the time difference caused by the change of speed when the ultrasonic beam propagates in the water upstream and downstream, analyze and deal with the flow rate of water, and then calculate the flow rate of water further.
