ABSTRACT:
A mass flowmeter comprises a pair of conduits with extremities restrained from lateral deflections disposed parallel to one another, each of which pair of conduits includes two end sections extending from the respective restrained extremities thereof and connected to one another by a curved or looped midsection, which two end sections are tied together by a clamp; wherein an electromagnetic vibrator exerting oscillating force for the two clamped combinations of the pair of end sections generates relative flexural vibration between the pair of conduits, and the mass flow rate of media moving through the pair of conduits is determined from the degree of asymmetry in the relative flexural vibration between the two opposite halves of the combination of the pair of conduits.
