摘要
气体流量计量是天然气输、配、销过程中重要的测量环节,它是企业进行贸易交接、经济分析以及降低运营成本的主要因素之一。在天然气输送管道与贸易计量中,确保流量计及体积修正仪的正常运行,对保障管道安全、经济、高效运行具有十分重要的意义。本文实现了一种流量计远程控制系统,包括对气体介质组分、仪表系数等参数的监测,对天然气运行管道压力、温度和体积流量的趋势分析,对流量计输出脉冲信号的诊断,以及对修正仪误差的在线检测。
Gas flow measurement is an important measurement link in the process of natural gas transmission,distribution and marketing. It is one of the main factors for enterprises to conduct custody transfer,economic analysis,and reduce operating costs. In natural gas transportation pipelines and trade measurement,ensuring the normal operation of flow meters and volume correctors is of great significance for ensuring the safe,economical,and efficient operation of pipelines. This paper implements a flow meter remote control system,including monitoring of gas medium components,meter coefficients and other parameters,trend analysis of pressure,temperature and volume flow of natural gas operating pipelines,diagnosis of flow meter output pulse signals,and correct the online detection of instrument error.
