Abstract

Apparatus and method for making fluid mass flow rate measurements using a Coriolis flow meter equipped with sensors which measure acceleration, velocity, or position of each side leg of an oscillating U-shaped conduit through which the fluid is passed. The sensors are so constructed and located as to produce analog signal outputs which accurately correspond to the motion of the respective side legs of the U-shaped conduit. When fluid is flowing through the conduit, a change from coincidence in the time relationship of the sensor signals caused by the divergent oscillations of each side leg of the U-shaped conduit is measured in both directions of oscillation. The fluid mass flow rate is then determined as a function of such time separation of the signals. The separation of the two signals with respect to time is measured without reference to static structures affixed to a platform.
