ABSTRACT:
A flow transducer for measuring the flow of a fluid, the transducer including a housing having two spaced apart depending legs with a shaft rotatably mounted between the legs, and a rotor secured on the shaft for rotation by the flow of fluid thereacross. In one of the legs is provided a chamber which houses a magnetic device also secured on the shaft for rotation with the rotor. The magnetic device produces a change in a magnetic characteristic as a function of the rotation of the rotor. A suitable sensor is contained in the housing adjacent to the magnetic device, and produces an electrical output responsive to the change in the magnetic characteristic.
