ABSTRACT:
A flow-rate measuring device comprises a chamber and an inlet channel for receiving and introducing a flow of fluid to the chamber. A wobble plate is pivotally disposed in the chamber to equally divide it into first and second chamber portions when in equilibrium position. First and second discharge channels are connected to the first and second chamber portions, respectively. Part of the chamber wall serves as an arcuate baffle extending between the first and second discharge channels. The pivot point of the wobble plate lies at the center of curvature of the arcuate baffle surface.
