flow meter (rotor) RRI- 010/ RRI-025 - Greisinger electronic
meter measures the flow rate with an impeller rotating due to the
flow. The flow rate is proportional to the rotational frequency. The
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:
