Research on Measuring Method of Emerson Mass Flowmeter

Emerson mass flowmeter is an inference flowmeter. The development, application and demand of flow measurement technology are interdependent. Application and demand are the driving force to promote the development of flow measurement technology. At present, Emerson flowmeter mass flow measurement has many measurement methods, including indirect measurement and direct measurement.
Emerson's mass flow meter measurement technology focuses on the direct measurement method of mass flow, thereby improving measurement accuracy and realizing high-precision and high-reliability measurement of various media under complex environmental conditions. The sensor is composed of a vibrating tube, a signal detector, a vibrating driver, a supporting structure and a shell. It can directly measure the mass flow of fluid in the pipeline, with high accuracy, high stability, good reliability, and large range ratio, suitable for high-viscosity fluids. The mass flow sensor is a phase-sensitive resonance sensor based on the Coriolis force effect.
The indirect measurement method of Emerson flowmeter mass flow, because of the introduction of multiple intermediate parameter measurement, and then calculation and correction, so the accumulated error is large, but because of its inheritance of traditional methods, easy to use, in some measurement accuracy requirements There are more applications where it is not high. In particular, it is widely used to measure the mass flow of gas or the volume of gas under standard conditions by means of compensation.
