Description
weFlux² flow sensors simultaneously measure flow velocity and the temperature of aqueous liquids regardless of position and flow direction. The advantage: The number of measuring points and the diversity of sensor variants are cut in half, ensuring the greatest possible flexibility when installing in closed piping systems. Either 2 switching outputs or 1 switching output and 1 analog output are available depending on application requirements. The outputs can be configured as desired via IO-Link in order to flexibly adapt the sensors to the respective application.
Features at a Glance
- A single sensor for flow and temperature
- FDA compliant
- Ready for Industry 4.0 with IO-Link 1.1
- Measurement independent of flow direction and instillation position
