Page 4: Operating Principle
5. Operating Principle KOBOLD Rotating Vane Flow Meters series DRH are used for measuring and monitoring low viscous liquids. Series DRH flow meters are working according 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. -
