ABSTRACT:
A mass flowmeter comprises a pair of conduits disposed in a side by side arrangement and flexurally vibrated relative to one another by an electromagnetic vibrator included at the midsection of the combination of the pair of conduits wherein each of the pair of conduits includes two flexible sections respectively included in the two opposite halves thereof, wherein a pair of relative motion sensors respectively measuring the relative flexural vibration between the first halves of the pair of conduits and the relative flexural vibration between the second halves of the pair of conduits provide two electrical signals including a difference therebetween that varies as a function of mass flow rate of media moving through the pair of conduits.
