Kobold DPE Turbine Wheel Flow Meter

Kobold DPE Turbine Wheel Flow Meter is used for measuring and monitoring liquids. The device works according the well-known blade wheel principle. The six vane blade wheel is retained axially in a high quality sapphire bearing. The sensor is supplied ready-to-install with pipe fittings or with weld-on sleeves.

Kobold DPE Turbine Wheel Flow Meter

The blade wheel is set in motion by the flowing medium. Magnets are embedded hermetically sealed in the ends of the blade wheels. The magnets generate electrical pulses in a Halleffect sensor mounted outside the flow area.
