- For high-accurate flow measurement by means of ultrasonic cross correlation method
- Interference-free connection over long distances through digital signal transmission
- Cable extensions over several 100 metres with standard cables possible without any problems
- Absolutely stable zero point and drift-free
- Measurement in slightly to heavily contaminated media
- Suitable for media with high solids loads
- Easy installation without additional constructions thanks to optimised mounting accessories
- Installation under process conditions possible
- Suitable for all channel cross sections
- The tailored selection of sensor constructions ensures the best possible solution for each application
CS2 flow velocity sensors are suitable for continuous measurement of slight to heavily polluted media in channels mainly featuring high levels.The wedge sensors are designed for mounting on channel walls, on the channel floor and on the inner walls of large pipes. In combination with transmitters such as NivuFlow 750 or NivuFlow 7550 and with level measurements integrated in the sensor or external level measurements, they form a complete flow measurement system.
Typical applications for CS2 wedge sensors
- Wastewater treatment plants: intake, discharge, activated sludge tank intakes, return sludge, recirculation, surplus sludge, digester discharge and flocculant dosage
- Industrial wastewater networks
- Large Collectors
- Particularly suitable for large channels featuring levels starting at 500 mm
