A mass flowmeter comprises a vibrating conduit secured to a support structure at the two extremities that includes two end sections connected by a looped midsection in such an arrangement that the two halves of the vibrating conduit over-lap one another at least once in a spaced arrangement therebetween; an electromagnetic vibrator exerting a vibratory force to the vibrating conduit at the over-lapping section, that generates relative flexural vibrations between the two halves of the vibrating conduit; and a pair of motion detectors respectively measuring the flexural vibrations of the two halves of the vibrating conduit, wherein the mass flow rate through the vibrating conduit is determined from the difference in the flexural vibrations between the two halves of the vibrating conduit.
