4. Wide applicability, the same sensor can be used for measuring multiple media

2、 The main parameters are shown in the table below:

3、 Measurement principle:

The CG-80 Coriolis mass flowmeter is manufactured based on the Coriolis force principle. Under the action of driving current, by applying a certain vibration frequency to the measuring tube, the magnetic field force and Coriolis force inside the tube will cause corresponding vibrations in the two measuring tubes (as shown in Figure 1-1). When the fluid is diverted to two parallel measuring tubes through the inlet flange splitter, the measuring tubes will undergo slight bending (phase difference) due to the Coriolis force, and the degree of bending of the pipeline is only related to the mass flow rate of the fluid flowing through it. By detecting the degree of curvature of the pipe wall, we can directly measure the mass flow rate.

4、 Working principle

The CG-80 Coriolis mass flowmeter measures fluid mass based on the Coriolis force phenomenon. When the measured medium flows through a pipeline at a velocity v and the pipeline rotates around an axis perpendicular to the direction of flow angular velocity, the force generated is called Coriolis force.

When the medium leaves the axis of rotation, it must accelerate to a higher and higher circumferential velocity (the required force is named Coriolis force after its discoverer), at which point the Coriolis force decreases in rotation; When the flow direction of the medium is in the same direction as the axis of rotation, the opposite effect occurs, and the Coriolis force amplifies the rotation.
