摘　　要：阐述在线多相流量计的开发原理和国内外低含液率气液两相流计量技术研究的主要技术路线。结合海上含液天然气流量计开发工作,全面系统地总结了流量计开发的技术路线和研究成果。详细介绍槽式孔板的单相流与两相流测量特性、基于双槽式孔板组合测量原理与软测量技术的流量计计量算法等内容,指出了需要进一步深入研究的方向。The methodology of on-line multiphase flowmeter development is introduced, especially on the gas-liquid two-phase flow measurement with low liquid fractions. Based on the project of offshore wet gas flowmeter development,the technical strategy,the main principle and the newly achievements of the research have been discussed. Both single-phase and two-phase flow characteristics of slotted orifice, which is a gas-liquid two-phase flow sensor, have been put forward. The measurement algorithm based on slotted orifice-couple and soft measurement techniques have also been proposed. At last some aspects deserved further investigations are put forward.
