Measurement principles

As a practical application of the Coriolis effect, the Coriolis mass flow meter operating principle involves inducing a vibration of the

flow tube through which the fluid passes. The vibration, though it is not completely circular, provides the rotating reference frame

which gives rise to the Coriolis effect. While specific methods vary according to the design of the flow meter, sensors monitor and analyze changes in frequency, phase shift, and amplitude of the vibrating flow tubes. The changes observed represent the mass flowrate and density of the fluid.


Mass flow measurement

The measuring tubes are forced to oscillate producing a sine wave. At zero flow, the two tubes vibrate in phase with each other.

When flow is introduced, the Coriolis forces cause the tubes to twist resulting in a phase shift. The time difference between the

waves is measured and is directly proportional to the mass flow rate.

Liquid flow rates

Micro Motion has adopted the term nominal flow rate, which is the flow rate at which water at reference conditions causes

approximately 14.5 psig (1 barg) of pressure drop across the meter.
