Introduction
The Coriolis mass flow meter is a new type of flow measurement instrument developed based on the Coriolis force principle. It can directly measure the mass flow rate, medium density, and temperature of fluids in closed pipelines. It can be widely used in industries such as chemical, petroleum, food, pharmaceutical, and papermaking.

Measuring principle
When a fluid flows through a rotating or vibrating tube, it generates a Coriolis force proportional to its mass flow rate. A fluid particle is subject to centripetal acceleration and Coriolis acceleration, from which the Coriolis force can be derived and expressed as a function of mass flow.
In practice, Coriolis mass flowmeters use a vibrating tube instead of a rotating one. With no flow, the tube vibrates in phase. As fluid passes through, Coriolis forces cause the two sections of the tube to twist in opposite directions, producing a phase difference directly proportional to the mass flow rate. By measuring this phase difference, the meter accurately determines mass flow, density, and other process variables.
