UFX Hand-held Doppler Ultrasonic Flow Meters

UFX Hand-held Doppler Ultrasonic Flow Meters

The UFX hand-held ultrasonic Doppler flow meter is a cost-effective flow measurement device for closed-pipe liquid systems containing suspended particles or gas bubbles. A non-invasive, hand-held transducer is placed on the outside of metal or plastic pipes and ultrasonic waves are transmitted into the flow stream.  The velocity of the particles or gas bubbles is determined by measuring the frequency shift of the reflected waves.


  • Quick detection flow velocities of liquids with particulates 


  • Non-invasive, hand-held transducer and battery-powered electronics packaged in a NEMA 4 (IP65) rated enclosure
  • Reliable readings on nearly all liquid applications containing a minimum of 100 ppm of 100 micron size suspended solids or entrained gases
  • Optional CE approved version for pipes size 1 in. (25 mm) and above
  • Large four-digit LCD display provides velocity readout in user selected units (FPS or MPS)
  • Easy-to-use flow verification instrument for industrial and municipal applications including concrete slurries, dredging, primary sludge and waste activated sludge
