本文首先对气液混合物流量和含气率的双参数测量的重要性和研究现状作了简要评价。作者在试验中使用串联的椭园齿轮流量计和孔板,试验用工质为空气—水混合物。在本研究报告中,得出了根据椭园齿轮流量计读数和孔板压差即能分别得出气体和液体流量的关系式,计算值与试验数据相比,气流量的均方根误差为2.9%,液体流量的4.4%。 In this paper, the importance and status quo of two-parameter measurement of gas-liquid mixture flow rate and gas content are briefly reviewed. The authors used a series of elliptical gear flow meters and orifice plates for the test, with the working fluid being an air-water mixture. In this study, the relationship between gas and liquid flow rates was obtained based on the readings of the elliptical gear flowmeter and the pressure drop across the orifice. Comparing the calculated values ​​with the experimental data, the root mean square error of the gas flow is 2.9%, 4.4% of liquid flow.
