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
flow rate 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.

Density measurement
The measuring tubes are vibrated at their natural frequency. A change in the mass of the fluid contained inside the tubes causes a
corresponding change to the tube natural frequency. The frequency change of the tube is used to calculate density.
Temperature measurement
Temperature is a measured variable that is available as an output. The temperature is also used internal to the sensor to
compensate for temperature influences on Young’s Modulus of Elasticity.

Liquid flow rates
Nominal flow rate
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.

Gas flow rates
When selecting sensors for gas applications, pressure drop through the sensor is dependent upon operating temperature, pressure,
and fluid composition. Therefore, when selecting a sensor for any particular gas application, it is highly recommended that each
sensor be sized using the Online Store Sizing and Selection Tool at the Emerson web site (www.emerson.com).
The table below indicates mass flow rates that produce approximately 25 psig (1.7 barg) pressure drop on natural gas with
molecular weight of 17 at 60 °F (16 °C) and 500 psig (34 barg).
