CSM Correlation Pipe Sensor
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.
Technical Instruction
Measure. Monitor. Repeat.
For better insights, better decision-making and better process performance.
Key Features & Benefits
- 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
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
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 mounting via nozzles on pipes.
