Earth’s Coriolis effect is relied upon by Coriolis flow meters in order to make fluid mass flow rate measurements. Inside a Coriolis meter’s flow body, flow gets diverted to two sensor flow tubes that are parallel to one another. An energized drive coil vibrates them in opposition to each other. The phase shift of the mass flow meter, which the Hall Effect sensors measure and that are mounted at the inlets and outlets of the sensor tubes, is the result of the Coriolis effect. It is directly proportional to the media mass that is flowing through the tubes. Therefore, the Coriolis flow meter is a real mass flow meter.
