2.1
Principle of Operation
The Coriolis measuring principle refers to the effect that a moving mass has on a body
in a rotating frame of reference. The moving mass exerts an apparent force on the body,
causing a deflection. This force is called the Coriolis force. It does not act directly on the
body, but on the motion of the body. This principle is used in Coriolis flow meters. A
Coriolis flow meter consists of two parallel tubes that are made to oscillate using a
magnet. These oscillations are recorded by sensors fitted at the inlet and outlet of each
tube. In a no-flow state, the oscillations are synchronized, since there is no mass
exerting any force on the tubes. Any fluid flowing through the tubes generates Coriolis
forces, causing the tubes to twist in proportion to the mass flow rate of the fluid.
