Abstract
Apparatus and method for metering the flow rate of a fluid through a conduit in which a low inertia transducer is placed between the inlet and outlet, the transducer having a substantially cylindrical housing and a rotatable element concentric to the housing which together define an arcuate pathway for the flow of the fluid. A pressure sensor generates a pressure error signal corresponding to a change in pressure between the inlet and outlet and translates the same into a detectable signal which is used to change the speed of the rotatable element to reduce the differential pressure between the inlet and outlet.
