flow meter (rotor) RRI- 010/ RRI-025 - Greisinger electronic
flow meter
properties: the flow
meter measures the flow rate with an impeller rotating due to the
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.))
