Abstract
A flowmeter is provided having a housing containing a swirling fluid stream, a rotor which is rotated by the stream, and a turbine which is displaced by the stream; and having a first, transverse angularly discrete, source of magnetic flux means rotating with said rotor and a first, transverse angularly discrete, detector of magnetic flux means mounted on the housing and providing a first output signal when said first source means and said first detector means are in transverse angular alignment, and a second transverse angularly discrete source of magnetic flux means, which may be said first source means, and a flux conductor angularly displaced in conjunction with said turbine, and a second detector of magnetic flux mounted on said housing and providing a second output signal when said second source means and said conductor are in transverse angular alignment.
