ABSTRACT:
A mass flowmeter comprises a conduit with two extremities secured to a support, which conduit includes a first and second end sections extending from the respective secured extremities thereof in a cantilever-like arrangement and a looped mid section of 360 degree loop angle connecting the first and second end sections of the conduit to one another, an electromagnetic vibrator inducing a relative flexural vibration between the two opposite halves of the conduit in directions approximately perpendicular to the looped midsection of the conduit, and a pair of vibration sensors respectively measuring the flexural vibration of the conduit at two sections respectively belonging to the two opposite halves of the conduit, wherein the mass flow rate of media moving through the conduit is determined as a function of difference in the flexural vibration between the two opposite halves of the conduit such as the phase angle difference between the two vibrations respectively measured by the two vibration sensors.
