Product Details

  • The DFM 5.1 monitors the flow rate of dirty or aerated liquids including: wastewater, chemicals, acids, slurries, abrasives and viscous liquids. Recommended for full pipes and any fluid that contains solids or bubbles
  • The strap-on sensor is mounted on the outside of a plastic or metal pipe ½ inch diameter or larger
  • Installation is easy - without shutting down the flow system. No contact is made with the moving fluid and no pipe cutting or drilling is required. There is no fouling or scale build-up on the sensor
  • The DFM 5.1 Doppler Flow Meter includes an ultrasonic sensor, a simple 5-key calibration system, a large digital flow rate display with totalizer, isolated 4-20mA output and two programmable control relays
  • Data logger and intrinsically safe sensor are optional
  • Measures flow in either direction and displays positive or negative values
  • To measure flow, an acoustic signal is reflected back to the sensor from moving particles or gas bubbles suspended in the fluid
