ABSTRACT:
A flow metering device designed to variably control the discharge from a variable displacement pump by detecting changes in momentum of the flowing fluid, which are proportional to the mass flow rates. The rate of discharge from the pump is then accurately controlled to a prescribed rate without being influenced by changes in viscosity of the fluid or where cavitation, bubbling, or the like occurs in the flow.
