flow meter (rotor) RRI- 010/ RRI-025 -  Greisinger electronic


flow meter


the flow meter measures the flow rate with an impeller rotating due to the
flow. The flow rate is proportional to the rotational frequency. The rotational
speed is measured by an inductive proximity switch.

  • no magnets, but with inductive sensor
  • largely wear-free due to high-quality ceramic axis and bearing
  • output signal NPN (optional PNP)
  • no inlet and outflow zone needed
  • uncomplicated flow measurement
  • intrinsically safe behaviour
  • modular design with several connecting systems
  • connections plug- and pivotable

area of application:

Sensor suitable for

  • water
  • oil (viskosity up to 10 mm2/s (10 cSt.))
