Abstract
The present invention provides a device for generating an electrical output signal representative of the flow rate through a fluid flow meter of the type having a mechanical output member movable in an amount proportional to the fluid flow rate. The device comprises the U-shaped magnet having a north and south pole and a Hall effect transducer positioned between the poles of the magnet. The transducer produces an electrical signal representative of the distance between the transducer and one of the magnetic poles. The magnet in turn is connected to the mechanical output member from the flow meter so that the magnet moves in unison with the output member from the flow meter thus varying the transducer electrical output. The output from the transducer is electrically connected to a conventional electrical indicator to produce an indication of the fluid flow rate through the flow meter.
