Flowmasonic WUF 620 CF Clamp-On Ultrasonic Flowmeter

WUF 620 CF series clamp-on transit-time ultrasonic flow meter utilizes transit-time principle. The transducer is mounted outside surface of the pipe without requirements of flow stop or pipe cutting. It’s very simple, convenient for installation, calibration and maintenance. Different sizes of transducers satisfy different measuring demand. Plus, select thermal energy measuring function to achieve completely energy analysis. It is widely applied in processing monitoring, water balance test, district heating balance test, energy efficiency monitoring as easy installation and simple operation advantages.
