Abstract
A flowmeter includes a conduit having an elbow portion and a straight section downstream of the elbow. A turbine is mounted inside the conduit in the straight section adjacent the elbow portion. The turbine occupies less than the entire cross section of the conduit and is disposed adjacent the side of the conduit which receives the laminar flow exiting from the elbow portion. A permanent magnet is mounted on the turbine, the rotation of which is picked up by a Hall-effect sensor mounted in a cavity in a wall of the conduit.
