ABSTRACT:
The flowmeter of the present invention comprises at least one combination of a rotatable member and at least one fluid dynamic target, wherein the fluid dynamic target is secured to the rotatable member in a pivoting relationship about a first axis generally perpendicular to the direction of the fluid flow, and the rotatable member is rotatably secured about a second axis off-set from and generally parallel to the first axis. The rotatable member is biased with a reaction torque about the second axis provided by the earth's gravitational force or by a mechanical spring that counter-acts the action torque generated by the fluid dynamic force on the fluid dynamic target. The magnitude of the angular displacement of the rotatable member from a reference position corresponding the the zero fluid velocity is directly or remotely measured as a measure of the fluid flow.
