The function of mass flowmeter is based on the Coriolis principle.The mass flow rate of liquids and gases can be calculated from the deformation of the measuring tube caused by the flow.The media density can also be derived from the resonance frequency of the vibrating tube.Two sensor coils are used to calculate the Coriolis effect.If there is no flow,both sensors record the same sinusoidal signal.Once a flow begins,the Coriolis force actson the floeing mass particles of the medium and causes the measuring tube to deform,resulting in a phase shift between the sensor signals.This phase shift is directly proportional to the mass flow.
