POA Correlation Wedge Sensor

POA flow velocity sensors are suitable for continuous measurement of slight to heavily polluted media.The wedge sensors are designed for mounting on channel walls, on the channel floor and on the inner walls of large pipes.

In combination with transmitters such as NivuFlow 750 or NivuFlow and with level measurements integrated in the sensor or external level measurements, they form a complete flow measurement system.

Measures: Flow

Measure. Monitor. Repeat.

For better insights, better decision-making and better process performance.

Key features & benefits:

  • For high-accurate flow measurement by means of ultrasonic cross correlation method
  • Interference-free connection over long distances through digital signal transmission
  • Cable extensions over several 100 metres with standard cables possible without any problems
  • Absolutely stable zero point and drift-free
  • Measurement in slightly to heavily contaminated media
  • Easy installation without additional constructions and perfectly matched mounting accessories
  • Fastening by means of screws or various optionally available fastening systems
  • Installation under process conditions possible
  • Suitable for all channel cross sections
  • The tailored selection of sensor constructions ensures the best possible solution for each application

POA Correlation Wedge Sensor

Typical applications for POA wedge sensors

  • Wastewater treatment plants: intake, discharge, activated sludge tank intakes, return sludge, recirculation, surplus sludge, digester discharge and flocculant dosage
  • Permanent measurements on stormwater treatment facilities such as stormwater overflow tanks, rainwater sedimentation and retention tanks
  • Direct discharge control, infiltration (extraneous water) or leakage detection
  • Industrial wastewater networks
  • and many more

Medium measurement range for levels up to ca. 1m

Ultrasonic sensors for flow measurement with very high accuracy in slight to heavily polluted media. For installation on channel wall or channel bottom
