Kobold DRG Rotating Vane Flow Meter

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.

Kobold DRG Rotating Vane Flow Meter

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.
