ABSTRACT:
A inertia force flowmeter comprises a conduit under a lateral reciprocating motion in directions perpendicular to a reference plane defined by the center line of the conduit, and a pair of differential pressure sensors respectively measuring two fluctuating differential fluid pressures resulting from the lateral reciprocating motion of the conduit at two different sections of the conduit, and a motion sensor detecting an amplitude of the reciprocating velocity of the lateral reciprocating motion of the conduit, wherein the mass flow rate of fluid media moving through the conduit is determined from a product of the ratio of the amplitude of the fluctuating differential pressure to the amplitude of the lateral reciprocating velocity of the conduit and a function of the phase angle difference between the two fluctuating differential fluid pressures.
