Coriolis Flow Meter

Introduction：

Coriolis flow meter is a direct and precise measurement of fluid mass flow meter to the main structure of the novel, U-shaped two side-by-side tubes, so that the curved parts of the two tubes slightly vibrate, and then the straight vibration situated on both sides.

Features：

When the Coriolis mass flowmeter is working normally, the vibration of the measuring tube causes the Coriolis force of the measuring medium in the tube. The greater the Coriolis force, the greater the friction between the flowing medium and the measuring tube wall, and the greater the pressure loss of the flowmeter. The Coriolis force is proportional to the flow rate of the measurement medium. Therefore, when selecting the Coriolis mass flowmeter, the influence of the measured medium flow rate should be considered. The influence of the medium flow rate on the selection of the Coriolis mass flowmeter is related to the measurement principle of the Coriolis mass flowmeter.

Obviously, the Coriolis mass flowmeter is mainly used to measure the mass flow rate of the medium or output the calculated volume flow rate. The selection parameters provided by the process professional only involve the medium mass flow rate or volume flow rate; therefore, the influence of the medium flow rate will be ignored. The measuring tube of Coriolis mass flowmeter has small amplitude, which can be regarded as no moving parts and no obstructing parts, and its measured value is not affected by the flow field in the pipeline.

Advantage
The Coriolis mass flowmeter is for direct measurement of mass flow;

It has high measurement accuracy, standard accuracy 0.2%; And the measurement is not affected by the physical properties of the medium.

The measurement can be relatively large, and the measurable ratio that generally guarantees basic accuracy is 10:1 or 20:1

There is no requirement for the length of the upstream and downstream straight pipe sections.

Wide range of applications; In addition to normal fluid measurement，a variety of high viscosity liquid, containing solids slurry, containing trace amounts of liquid gas also can be measured.

The Coriolis mass flowmeter is a highly intelligent instrument. In addition to the mass flow rate, the transmitter can output the process parameters such as volume flow, density, temperature, viscosity and concentration converted into 4-20mA or pulse signal or bus signal.
