Most of the coriolis flowmeters on the market at present are devices for directly measuring mass flow by using the principle that coriolis force proportional to mass flow is generated when fluid flows in a vibrating pipeline, and the coriolis flowmeters are composed of a flow detection element and a converter, and realize direct measurement of mass flow, but liquid in the flowmeters has certain weight due to the fact that the liquid extrudes the outer wall of the flowmeter due to the weight of the liquid in addition to the extrusion of the outer wall of the flowmeter due to the liquid flow when measurement is performed, flow errors caused by the weight of the liquid are generally ignored in actual measurement, but the accuracy of measurement may be reduced due to the fact that the factor is ignored under the requirement of accurate measurement.
