Flow meter model DRB is used for measuring and monitoring liquids. The device works according the well-known blade wheel prin-ciple. The four vane blade wheel is retained radially in a highquality sap-phire bearing. The sensor is supplied ready-to-install with pipe fi ttings or with weld-on sleeves.

The blade wheel is set in motion by the fl owing medium. Magnets are embedded hermetically sealed in the ends of the blade wheels. The magnets generate electrical pulses in a Hall-effect sensor mounted out-side the fl ow area. Various electron-ics units can be used to display and monitor the volumetric flow.
