Coriolis flow meters are devices used to measure the flow rate of fluids in pipes. They operate on the principle of the Coriolis effect, which is a phenomenon where a moving fluid experiences a force that is perpendicular to its direction of motion and to the axis of rotation. This effect is caused by the rotation of the Earth, but it can also be artificially induced in a laboratory setting.

In a Coriolis flow meter, the fluid to be measured flows through a tube that is oscillated at a specific frequency. The oscillation causes the fluid to experience a Coriolis force, which deflects the fluid in a direction perpendicular to its flow and the axis of oscillation. This deflection is proportional to the mass flow rate of the fluid.

The deflection of the fluid is detected by sensors located at the ends of the tube. These sensors measure the phase shift between the input and output signals, which is proportional to the mass flow rate. The flow rate can then be calculated using the known properties of the fluid and the geometry of the tube.

Coriolis flow meters are highly accurate and can measure a wide range of flow rates. They are also suitable for measuring the flow of viscous fluids and fluids with suspended solids. However, they are more expensive than other types of flow meters and require more complex installation and maintenance.
