Analysis of Advantages and Disadvantages of Coriolis Mass Flowmeters - Focus on Microfluidic Control Technology
In the actual production process, the volumetric flow rate often receives the influence of the working pressure, temperature, viscosity, composition, etc. of the measured medium, which brings a large error to the flow measurement. Therefore, in order to accurately measure the fluid, it is necessary to measure the fluid. Mass flow. Coriolis mass flowmeter is a Coriolis force generated by a vibrating tube to accurately measure the mass flow of a fluid. The density, viscosity, conductivity, fluid state, temperature, etc. of the fluid do not affect the accuracy of the meter measurement. . Analysis of Advantages and Disadvantages of Coriolis Mass Flowmeter Application advantage: 1. The measurement accuracy is high. The measurement accuracy of general flow meter is between 0.5% and 1.0%, and the accuracy of Coriolis mass flowmeter can reach ±0.2%. 2. There are no obstacles in the pipeline, no moving parts, few failure factors, easy to clean, convenient for maintenance and maintenance. 3. Wide measurement range, oil, chemical media, gas, and high viscosity media can be measured. 4. Easy to install, it can be installed without straight pipe. 4. Can measure non-full tube media. 5. Ability to directly measure mass flow without being affected by factors such as temperature, pressure, viscosity and density. Disadvantages: 1. Low density media and low pressure gas cannot be measured. 2. Not resistant to vibration, sensitive to vibration. 3. It is expensive and used for occasions with high measurement requirements. 4. Cannot be used for the measurement of larger diameters. The current maximum diameter is DN150. Summary: Coriolis mass flowmeters are not omnipotent. They have advantages in measurement and measurement defects, so be careful when using them.
