Series DRH fl ow meters are working according the wellknown rotating vane principle. A magnet fi tted 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 fl ow to a frequency signal. A seriesconnected electronics unit converts the signal to an analogue output, limit contacts or display.
This devices can be adapted to prevailing plant conditions with the 360° rotatable screw connections.
