PARTLY FILLED PIPES AND OPEN CHANNELS.

UFM – AVFM – The Area Velocity FlowMeter is especially suitable for open channels, partially filled pipes and pipes without a flume or weir. Ideal for (industrial) waste water, effluent, rainwater and irrigation water.

The ultrasonic sensor continuously measures both speed and level to determine the flow in an open channel or partially filled pipe. The completely sealed sensor is resistant to contamination, corrosion and abrasion and is mounted on the bottom of the pipe or channel. Careful selection of the sensor mounting location results in the best performance and maintenance-free operation. Avoid locations where sediment builds up.

  • No flume or weir required
  • Three 4-20mA outputs
  • Two control relays
  • Measures reverse flow
  • Modbus® RTU optional

  • Velocity Measurement Range : ± 0.1 to 20 ft/sec and reverse flow to -5 ft/sec – in most applications
  • Pipe Diameter : from 6″ (150mm)
  • Measurement Accuracy : Level ± 0.25% | Speed ± 2.0%
  • Operating Temperature : 5 to 175°F (-15° to 80°C)
  • Display : Flow rate, relay status, totalizer, operating mode and calibration menu
  • Power Input : 100-240VAC / 50-60Hz, max. 10VA – optional: 9-32VDC, max. 10 watt
  • Outputs : 3x isolated 4-20mA, 1000 ohm (Flow, Level and Velocity) or 0-5VDC (by menu selection)

  • Wastewater
  • Industrial effluent
  • Stormwater
  • Combined sewers
  • Natural streams
  • Irrigation water

We can imagine that you are only incidentally in need of flow metering equipment. With us you can rent the UFM – Area Velocity FlowMeter per day or per week. Perform the measurements yourself, or leave it to our service engineers. We are happy to assist you with technical advice and support.
