Flow Sensors
CS2 Correlation Pipe Sensor
Part No. CS2-V1Large measurement range for big pipes
Ultrasonic sensors for flow measurement with very high accuracy in slight to heavily polluted media. For installation in pipes up to 5000 mm diameter
- Very high accuracy by means 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
- Installation under process conditions possible
- Particularly suitable for pipe sections starting at 1000 mm diameter
CS2 flow 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 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
- Industrial wastewater networks
