摘要
计量系统是天然气长输管道中的重要组成部分,介绍了长输管道计量系统中常用流量计特点,给出了计量系统仪表选型及设计的一般过程,详细说明了精度考虑、口径考虑、流速计算及回路配置等问题的设计原则及计算方法。给出了以气体超声流量计、在线气体色谱分析仪、流量计算机等构建的体积流量和能量流量的计量系统的典型配置。
Flow measurement system is an important component in long-distance natural gas transportation pipe; flowmeters usually used in gas metering are introduced and compared in this paper. Meter selection and general design procedure are also given out including accuracy consideration,dlameter consideration,velocity calculation,loop configration,etc.A typical metering system based on ultrasonic meter,online chromatographic analyzer,flow computer is constructed.
