ABSTRACT:
A mass flowmeter comprises a conduit of a looped configuration with two extremities secured to a rigid support wherein each of the two half sections of the conduit extend from each of the two secured extremities of the conduit and is curved over a loop angle generally equal to or less than 315 degrees, and the two half sections of the conduit over-lap one another over a portion thereof with a space therebetween; wherein an electromagnetic vibrator exerts a vibratory force on the over-lapping portion of the two half sections of the conduit generating a relative flexural vibration between the two half sections of the conduit, and a pair of motion sensors respectively measure the flexural vibrations of the two half sections of the conduit, which combination determines mass flow rate of media moving through the conduit from difference between two flexural vibrations respectively measured by the two motion sensors.
