Abstract
A flow meter apparatus for measuring the mass flow rates of fluids passed through two essentially parallel, cantilever mounted U-shaped flow tubes where, instead of the fluid serially passing through one of the U-shaped flow tubes and then through the second U-shaped flow tube, the fluid is essentially evenly divided and half of the fluid is passed through one U-shaped flow tube and the other half of the fluid is passed through the other U-shaped flow tube. The two U-shaped flow tubes are sinusoidally driven as the tines of a tuning fork, and when a fluid is passed through the oscillating U-shaped flow tubes Coriolis forces are generated which torsionally deflect the U-shaped flow tubes. Such torsional deflections are a function of the mass flow rate of the fluid passing through the two U-shaped flow tubes.
