Flowmasonic WUF 620 J Ultrasonic Portable Flow Meter



Flowmasonic WUF 620 Transit-time ultrasonic flow meter utilizes the difference of ultrasonic pulse forwarding and reversing flow rate to measure flow. Use a pair of transducers to transmit and receive signal alternately. Transducer signal travels faster downstream than upstream. Obtain transit-time △t by measuring signal travel time in downstream and upstream, the average flow velocity can be detained according to △t and velocity V. The volume flow Q can be calculated out of the flow velocity V and pipe profile S.

Flowmasonic WUF 620 J Series Flowma Portable clamp-on transit-time ultrasonic flow meter utilizes transit-time principle. The Flowmasonic 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.

When selecting a measurement site, it is important to select an area where the fluid flow profile is fully developed to guarantee a highly accurate measurement. Use the following guidelines to select a proper installation site:

  • Choose a section of pipe that is always full of liquid, such as a vertical pipe with flow in the upward direction or a full horizontal pipe.
  • Ensure enough straight pipe length at least equal to the figure shown below for the upstream and downstream transducers installation.
  • Ensure that the pipe surface temperature at the measuring point is within the transducer temperature limits
  • .Consider the inside condition of the pipe carefully. If possible, select a section of pipe where the inside is free of excessive corrosion or scaling.
