Flow Sensors

CSM Correlation Pipe Sensor

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

[Translate to English:] Kompakter Fließgeschwindigkeitssensor für Rohre

[Translate to English:] Sehr genaues Durchflussmessverfahren

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
