Abstract:Flow measurement of gas-containing liquids is a measurement problem faced by Coriolis mass flowmeters. Higher requirements are imposed on the drive technology and signal processing technology of Coriolis mass flowmeters. To this end, from the three core technologies of driving, signal processing and error correction, the Coriolis mass flowmeter is used to measure the flow of gas-containing liquids, and the difficulties of driving, signal processing and error correction techniques under the flow of gas-containing liquids are analyzed. The best driving technology, signal processing technology and error correction technology for gas-containing liquid flow are summarized for the difficulties. Analysis of the gas-containing liquid flow rate The reason for the large original measurement error of the Coriolis mass flowmeter and the measurement accuracy corrected by the correction method still cannot achieve the single-phase flow measurement accuracy of 0.1. In order to improve the accuracy of the Coriolis mass flowmeter to measure the flow rate of gas-containing liquids.
