ABSTRACT:
A mass flowmeter comprises a conduit with two end sections respectively extending from the two secured extremities of the conduit and connected to one another by a curved midsection of the conduit, an electromagnetic vibrator vibrating the two opposite halves of the conduit relative to one another in directions generally parallel to a plane including the curved midsection of the conduit, and a pair of motion sensors respectively measuring flexural vibrations of the two opposite halves of the conduit; wherein mass flow rate of media moving through the conduit is determined from the phase angle difference between two flexural vibrations respectively measured by the two motion sensors.
