Coriolis Mass Flow Meter Working Principle

What is a Coriolis flow meter? The structure of the Coriolis mass flowmeter is a double bend pipe structure, and its measurement principle is to detect the mass flow in the pipeline by measuring the
Coriolis force (referred to as Coriolis force) acting on thedouble bend pipe.

 

When two conditions are met:

(1) The double curved pipe vibrates at a certain frequency. (2) When there is fluid flow in the pipe, a new force - Coriolis force will be generated. This force is an additional force generated by the synthesis of pipe
vibration and pipe fluid flow. force,which produces a torque on the bend that causes the bend to twist symmetrically about its centerline. The electrical signal is detected by the displacement sensors on both sides
of the elbow, and then the electrical signal is processed to directly obtain the mass flow rate.

 

The Coriolis force is proportional to the mass m and velocity v of the moving fluid, (the product of mass and flow velocity)

By measuring the Coriolis force in the pipe, its mass flow can be measured.

 

  vibration and flow

 

The fluid generates a vortex in one direction during the vibration (fixed angular velocity ω), and flows forward under the push of pressure. For relative motion in a uniformly rotating reference frame, an inertial
force different from the usual centrifugal forceacts on the object, and this force is called (composite centrifugal force) = Coriolis force
