Abstract
A mass flowmeter comprises at least one conduit supported by a frame structure in a relationship allowing an enhanced pivotal vibration about two mutually orthogonal pivot axes, an electromagnetic vibrator generating a primary pivotal vibration of the conduit about one of the two mutually orthogonal pivot axes, and a pair of vibration sensors respectively included in two opposite halves of the conduit respectively located on two opposite sides of a plane including the other of the two mutually orthogonal pivot axes; wherein the mass flow rate of media moving through the conduit is determined as a function of an electrical variable such as the phase angle difference between two alternating electrical signals respectively generated by the pair of vibration sensors, which electrical variable represents the ratio of the amplitude of the secondary pivotal vibration to the amplitude of the primary pivotal vibration.
