What is a Coriolis Flow Meter?

Coriolis flow meters rely on the Earth’s Coriolis effect to measure fluid mass flow rates. Inside the flow body of a Coriolis meter, flow is diverted into two parallel sensor flow tubes, which are vibrated in opposition to one another by an energized drive coil.

The mass flow meter’s phase shift, measured by Hall Effect sensors mounted at the sensor tubes’ inlet and outlets, is caused by the Coriolis effect and is directly proportional to the mass of the media flowing through the tubes. Thus, the Coriolis flow meter is a true mass flow meter.
