CS2 Correlation Pipe Sensor

Part No. CS2-V1

Large measurement range for big pipes

Ultrasonic sensors for flow measurement with very high accuracy in slight to heavily polluted media. For installation in pipes starting at 1000 mm diameter

  • Very high accuracy 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
  • Particularly suitable for pipe sections starting at 1000 mm diameter

CS2 flow velocity sensors are suitable for continuous measurement of slight to heavily polluted media.
The pipe-shaped sensors are designed for installation in pipes from the outside using a nozzle. 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 pipe sensor

  • Channel networks: billing measurement places, flow measurement in large pipe sections
  • Wastewater treatment plants: intake, discharge, activated sludge tank intakes, return sludge, recirculation, surplus sludge, digester discharge and flocculant dosage
  • Industrial wastewater networks
  • and many more
