Abstract
An inertia force flowmeter comprises at least one conduit (1), an electromagnetic vibrator (11) generating a transverse reciprocating motion of the conduit (1) and a pair of differential pressure sensors (12 and 13) detecting the fluid pressure gradient in directions parallel to the directions of the transverse reciprocating motion of the conduit (1) respectively at two different sections of the conduit (1), wherein the mass flow rate is determined as a function of phase difference between two alternating electrical signals respectively provided by the two differential pressure sensors (12 and 13).
