ABSTRACT:
A Coriolis mass flow rate measuring apparatus including one or more detecting means (46), (48), (56) for detecting conduit detection portion velocities caused by Coriolis forces exerted by a mass flowing through the oscillating conduit, and means (54) operative to measure the time differences between said first and second points in time when respective velocity signals have zero velocity and to use such measurements according to the formula ##EQU1## to indicate the mass flow rate.
