CSP Correlation Wedge Sensor
Part No. CSPLarge measurement range for high flow levels
Flow velocity sensor for continuous measurement in slightly to heavily polluted media in channels with mainly high filling levels.
- For flow measurements with very high accuracy through ultrasonic cross-correlation method
- Absolutely stable zero point and drift-free
- Measurement in slightly to heavily contaminated media
- Simple installation without additional fixtures and optimised mounting accessories
- Installation possible under process conditions
The CSP flow velocity sensors are suitable for continuous measurement in slightly to heavily polluted media in channels with mainly high filling levels. The wedge sensors are designed for mounting on the channel floor or on the channel wall. In combination with the NivuFlow Mobile 750 transmitter, they make a complete flow measurement system..
Typical applications for the CSP wedge sensor
- Measurement campaigns in the sewer network
- Precipitation discharge measurements
- Wastewater treatment plant: inlet, outlet
- Industrial wastewater networks
- Large collecting sewers
- Particularly suitable for large sewers with fill levels from 500 mm
