The CNU06V3 is one of our new ultrasonic sensors for continuous level measurement without contact in liquids. Fast commissioning with its radio configuration using Avelour software that offers pre-assisted calibration.


Level sensor CNU06V3

This ultrasonic level sensor is intended for process applications by connection to a PLC in Modbus or 4-20mA. The CNU06V3 offers many advantages including its quick configuration by radio without line break.



Level Sensors CNU06V3


Measuring range

The CNU06V3 sensors measure from 0.3 and typically up to 6 meters. Ultrasonic power can be adjusted and the obstacles filtered


Configuration by radio

Configuration of the sensors and data analysis can done locally by radio, safely using the connection kit including Avelour 6 software.


Multi channel display

The sensor can be connected to a Modbus display for real-time data visualization
