Flow monitor and flow switch

Flow sensors

Available in:

3 Series

Thermal flow monitors can be used to monitor process fluids in a switching manner. Our measuring devices can be found in machine tools, on pumps and compressors, for example.

With our variants for screwing in or for direct inline installation, you can reliably solve different requirements in a wide range of applications. We have the right flow monitor or flow sensor for you, whether for monitoring the flow velocity or the volume flow of water and other liquids, such as coolants.

The special features

  • No moving parts, therefore resistant to contamination
  • Flow rate of liquid media can be measured directly
  • Screw-in or inline designs, depending on the flow rate/pipe diameter
  • Easy to integrate robust M12 connector
  • Visualize flow rate via LED line or display
  • UL and CE approval
  • Flow monitoring in piping
