Principle of Coriolis mass flowmeter
The mass flow meter consist of mass flow sensor and mass flow transmitter.It uses the Coriolis effect principle. By measuring the Coriolis force of fluid received in the tube, it can directly measure the mass flow of the fluid in the tube. The Coriolis force is only related to the mass and speed of the fluid. In principle, it eliminates the influence of temperature, pressure, fluid state, density and other parameters on the measurement accuracy, and directly obtains the accuracy flow value and density value of various media under complex environmental conditions. It doesn't need to go through the conversion of intermediate parameters, avoiding measurement errors due to the intermediate conversion, so as to realize the high-precision and accurate measurement.
