Flow Sensors

CSM Correlation Pipe SensorNew

Part No. CSM-V100 R

for up to 16 bar as well as temporary flow measurements

Ultrasonic sensors for flow measurement with very high accuracy in slight to heavily polluted media. For pipe applications

  • For high-accurate flow measurement 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
     

 

The CSM pipe 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 POA pipe sensors

  • For temporary flow measurements 
  • Validation of existing measurements
  • Wastewater treatment plants: intake, discharge, activated sludge tank intakes, return sludge, recirculation, surplus sludge, digester discharge and flocculant dosage
  • Direct discharge control, infiltration (extraneous water) or leakage detection
  • Industrial wastewater networks
  • and many more
