摘要
An inertia force mass flowmeter comprises at least one conduit under a lateral reciprocating motion with its amplitude distributed along the center line of the conduit in a symmetric or antisymmetric mode about the center section of the conduit, two differential or absolute pressure sensors detecting the alternating transverse pressure gradient existing in the fluid contained in the conduit in directions parallel to the direction of the lateral reciprocating motion of the conduit respectively at two different sections of the conduit respectively included in the two opposite halves of the conduit, and data processing device that determines the mass flow rate of fluid moving through the conduit as a function of an electrical variable related to a phase angle difference between two alternating electrical signals respectively representing the alternating transverse pressure gradient detected respectively at the two different sections of the conduit by the two differential or absolute pressure sensors.
