ABSTRACT:
A mass flowmeter comprises a conduit with two extremities secured to a rigid support, wherein two sections of the conduit respectively extending from the two secured extremities of the conduit are connected to one another by a curved midsection, that is vibrated in direction generally parallel to the plane including the curved midsection by an electromagnetic vibrator at a natural frequency, wherein the mass flow rate of media moving through the conduit is determined from the phase angle difference in the flexural vibration of the conduit between the two halves of the conduit, which information is provided by a pair of motion sensors respectively measuring the flexural vibrations of the two opposite halves of the conduit.
