Tianjin Petrochemical Company measures the Fan-yong

Abstract:Coriolis force mass flowmeters because of a direct measurement of mass flow to the advantages in China from the early 1990s to enter the field of industrial measurement, the application of more and more extensive. Early mass flowmeter manufacturers have claimed that their products are not tested medium density, temperature, pressure, viscosity change, with the large number of applications in recent years, the survey found that the medium changes in the physical parameters of its measurement Accuracy is influential. This paper discusses the changes in measured media pressure on the flowmeter accuracy of measurement.
Key words: Coriolis force, mass flowmeter, measurement accuracy, media measurement, work stress, error

1. Coriolis force of the principle of mass flowmeter

Coriolis mass flow meter is the use of mass flow of fluid vibration of the oscillation of the modulation of the Coriolis effect is the phenomenon of principle, to measure the quality of traffic for the purpose of mass flowmeter. General by the sensor and transmitter components.
