Is there a difference in the measurement of liquid and gas by mass flowmeter?
Direct measurement of the mass flow of fluid in the pipelineWith high accuracy and repeatability, it can directly measure the mass flow rate of fluid with high accuracy in a large range ratio.High accuracy of measurementThe mass flow measurement accuracy of the flowmeter is 0.2; At the same time, it can accurately measure the temperature and density of the fluid medium.Stable and reliable workThere are no obstacles and moving parts inside the flowmeter pipe, so it has high reliability, long life and small maintenance. Easy to use and safe.Suitable for the surface width of the fluid mediumIn addition to uniform fluids of general viscosity, high viscosity, non-Newtonian fluids can also be measured; It can not only measure the fluid parameters of a single solution, but also measure the mixed multiphase flow. Whether the medium is laminar flow or turbulent flow, the measurement accuracy is not affected.A wide range of applicationsMeasurement and monitoring can be implemented in petrochemic...

Factors affecting the measuring accuracy of mass flowmeter
The characteristic of mass flowmeter is that it can directly measure the mass flow rate of medium, and is not affected by the pressure, temperature and other factors of the working state of medium. Factors affecting the measuring accuracy of mass flowmeter:1. Impact of environmental vibrationMass flowmeters can operate in vibration environments, but must be isolated from vibration, for example, with a flexible pipe connection and vibration isolation support frame. But the vibration frequency should be prevented from being the same as the working frequency or harmonic frequency of the mass flowmeter. When multiple meters of the same model are installed in series or close parallel, especially when installed on the same support platform, the working frequency vibration of each mass flowmeter will affect each other, causing abnormal vibration, which will make the meter unable to work seriously. When ordering can be specially proposed to the manufacturer, staggered two series mass flowm...
Mass flowmeter market share is rapidly increasing
With the continuous deepening of industrial automation technology in all walks of life, especially in the mass flowmeter industry, for the mass flowmeter is to create infinite possibilities, the application of mass flowmeter in the industry is more and more extensive, more shows the importance of industrial automation for the mass flowmeter, only in the development of industrial automation is fully prepared to meet the test of the market, Mass flowmeters were able to achieve rapid growth.With the progress of social development, in order to catch up with the pace of The Times, enterprises have been in the pursuit of faster, more efficient, but in the pursuit of speed, also do not forget the pursuit of quality and technology. The same is true of the mass flowmeter industry.Mass flowmeter with its own simple operation, powerful function, exquisite technology so that their position in the industry quickly improved, so that we can in the field of cooperation and market expansion, play a...
Analysis and solution of common faults of mass flowmeter
Mass flowmeter based on Coriolis force is a kind of flow measuring instrument with high accuracy, high technology, stable and reliable operation. Now it is widely used in a series of occasions such as single well metering, joint metering and liquefied gas metering in Tuha oilfield, and some faults have been exposed. This paper focuses on analyzing how to deal with the failure and maintenance of mass flowmeter, and use mass flowmeter reasonably and effectively.1 IntroductionMass flowmeter is a kind of flow measuring instrument with high precision, high technology, stable operation and reliability. It can directly measure the mass flow of fluid. With the development of social economy and technology, mass flowmeter is more and more widely used in on-site measurement and trade settlement. At present, a large number of Coriolis mass flowmeters have been introduced and applied in various occasions. The use of this flowmeter has greatly promoted the improvement of measurement level, but als...
