A mass flowmeter is a description of the displacement of a particle undergoing linear motion in a rotating system due to inertia relative to the linear motion of the rotating system.   

A mass flowmeter is a typical application of Coriolis force, which allows the fluid being measured to pass through a vibrating measuring tube. The flow of the fluid in the pipeline is equivalent to linear motion, and the vibration of the measuring tube produces an angular velocity. Since the vibration is driven by an external electromagnetic field and has a fixed frequency, the Coriolis force that the fluid experiences in the pipeline is only related to its mass and velocity. The product of mass and velocity, that is, the flow velocity, is the mass flow rate that needs to be measured. Therefore, by measuring the Coriolis force that the fluid experiences in the pipeline, its mass flow rate can be measured.

Main purpose and scope of application

Mass flow meters can play a very effective role in various fields such as ingredient and batch measurement of various inputs, measurement and control of material flow rate during the process, rapid and variable density measurement, and product quality monitoring.

The Coriolis mass flowmeter is mainly used to measure the mass flow rate, total amount, and density of the medium. At the same time, it can also measure the volume flow rate and total amount, medium temperature, moisture content, alcohol content, concentration of two liquids mixed evenly, and raw material ratio in the process flow. It is mainly applicable to the following industries:

(1) The petroleum industry, such as crude oil production measurement, water content measurement, single well production measurement, and crude oil transportation measurement

(2) Chemical industry

(3) Food industry

(4) The pharmaceutical manufacturing industry, such as liquid drug production measurement

(5) The papermaking industry, such as pulp measurement

(6) Textile printing and dyeing industry
