天然气流量积算仪的软件设计

The Software Design for Parameter Compensation of Natural Gas Flow Measuring

天然气的计量都以标准状态体积流量和质量流量计算,各测量工况下的流量必须折算为标准状态的体积或质量流量。其折算系数和诸多因素有关,因此必须根据测量条件下的温度、压力进行补偿,本文介绍了天然气流量测量修正系数三维数据表的建立、数据插入方法和查表程序的软件设计,该软件在天然气流量积算仪中得到有效的应用,取得了良好的效果。

The standard volume flow and mass flow of natural gas are related to measuring condition of natural gas, so the compensation is necessary based on the temperature and pressure in measuring condition. The soft- ware design for establishing three-dimensional table for modified parameters, inserting data method and checking table program is introduced, and it is used effectively in natural gas flow totalizer.
