ABSTRACT:
A mass rate of flow meter with a first magnet and sensing coil for detecting the passage of an unrestrained rotor past the sensing coil. The position of a restrained turbine reactor is sensed by locating an axially extending magnetic flux linkage near the periphery of the turbine with an extension that is disposed in an axially overlapping relationship with a magnet that extends from the periphery of the rotor. A flux collecting ring on the periphery of the turbine is coupled to the magnetic flux linkage to provide a low reluctance magnetic circuit that couples flux from the first magnet to the sensing coil.
