NIVUS - Model CS2-V1 -Correlation Pipe Flow Sensor

• 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.

• 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
• and many more
