Clamp-on Ultrasonic Flowmeter

What Is a Clamp-On Ultrasonic Flow Meter?

A clamp-on ultrasonic flow meter measures liquid flow by attaching the sensor to the outer surface of the pipe without cutting into the pipe. Its compact display-and-sensor design, installation technology that requires no coupling gel, and 4-20 mA and Modbus outputs allow it to be quickly integrated into existing facilities.
