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.

The main classification :

The quality flowmeter can be divided into two categories: the direct type and the direct output of the

mass flow On the other A class of indirect or derivation, such as the combination of ultrasonic flow

 meters and densitometry, is used to multiply their outputs to produce mass flow
