ABSTRACT:
A pivotable vane flowmeter comprises at least one pivotable vane disposed pivotably about a pivot axis parallel to the the direction of fluid flow and experiencing a fluid dynamic torque created by the fluid flow, a bias spring or counter-weight providing a bias torque counter-acting the fluid dynamic torque, and a rotary position sensor detecting the rotary position of the pivotable vane about the pivot axis, wherein the dynamic pressure of the fluid flow is determined as a function of the rotary position of the pivotable vane about the pivot axis, and the time rate of the fluid flow is determined from a combination of the dynamic pressure of the fluid flow and the known or measured value of the fluid density, or from another combination of the dynamic pressure of the fluid flow and the frequency of rotation of a rotating turbine or propeller installed in conjunction with the pivotable vane flowmeter.
