Kobold DRG Rotating Vane Flow Meter

Description

Kobold DRG Rotating Vane Flowmeters is used for measuring and monitoring low viscous liquids. Series DRG flow meters are working according to the well-known rotating vane principle. A magnet fitted in the vane and hermetically sealed from the medium transfers non-contacting the rotary motion to a Hall-effect sensor mounted in the housing.

The sensor converts the rotary motion which is proportional to the flow to a frequency signal. A series-connected electronics unit converts the signal to an analog output, limit contacts or display.
