Flowmasonic WUF 620 CF Clamp On Ultrasonic Flow Meter

Flow Masonic WUF 620 CF transit-time ultrasonic flow meter utilizes transit-time principle, including clamp-on and insertion.


Flowmasonic WUF 620 CF transit-time ultrasonic flow meter utilizes transit-time principle, including clamp-on and insertion. When install clamp-on transducer, without flow stop and pipe cutting, simple installation and convenient for online comparison. Different sizes of transducers can measure different sizes‟ pipe. Insertion installation effectively solves clap-on flow meter can not accurately measure with scaling pipe and non-conductive media. Insertion transducer has stop ball valve, without flow stop or pipe cut, easy to install.

User also can mount hoops on unweldable pipe surface. Optional thermal energy measuring function. Widely applied in processing monitoring, water balance test, district heating balance test, energy efficiency monitoring etc.
