CS2 Correlation Sensor

Large measurement range for high flow levels

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


  • For high-accurate flow measurement by means of ultrasonic cross correlation method
  • Interference-free connection over long distances through digital signal transmission
  • Cables can be extended without any problems using standard cables
  • Absolutely stable zero point and drift-free
  • Measurement in heavily polluted and abrasive media
  • Easy installation without additional constructions and perfectly matched mounting accessories
  • 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


CS2 flow velocity sensors are suitable for continuous measurement of slight to heavily polluted media in channels mainly featuring high levels.
The wedge-shaped sensors are designed for installation on either the channel wall or the channel bottom. Combined with transmitter types such as NivuFlow 750 and an external level measurement the result is a complete flow measurement system.

Typical applications for CS2 sensors

  • Wastewater treatment plants: intake, discharge, large pipe, activated sludge tank intakes, return sludge, recirculation, surplus sludge, digester discharge and flocculant dosage
  • Industrial wastewater networks
  • Large Collectors
  • Particularly suitable for large channels featuring levels starting at 500 mm
