Abstract
A fluid flow monitoring device includes a housing defining a fluid flow passageway. A vane positioned within this passageway moves to positions which vary in accordance with the rate of fluid flow therethrough. An armature coupled to the vane pivots to positions corresponding to the vane positions. A submersible transformer in proximity to the armature produces an output signal indicative of the armature position and the fluid flow rate. The output signal is fed to a meter where the fluid flow rate is represented. A bypass passageway is provided for fluid flow therethrough in the event the fluid passageway becomes obstructed.
