- Very high accuracy 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
- Particularly suitable for pipe sections starting at 1000 mm diameter
The pipe sensors are designed for mounting from the outside into the pipelines using nozzles. In combination with transmitters such as NivuFlow 750 or NivuFlow 7550 and an additional external level measurement, they form a complete flow measurement system for part filled applications. They can also be used for permanently full pipes or Channels. The additional height measurement can be omitted here.
Typical applications for CS2 pipe sensor
- Channel networks: billing measurement places, flow measurement in large pipe sections
- Wastewater treatment plants: intake, discharge, activated sludge tank intakes, return sludge, recirculation, surplus sludge, digester discharge and flocculant dosage
- Pump stations: pumped quantities
- Industrial wastewater networks
- and many more
