天然气输差就是购气量与销售气量之间的差额。对于中游的天然气公司来说,就是向上游气源公司购买的气量与销售给下游燃气公司的气量差额。一、输差成因分析1.计量误差(1)单位的统一由于天然气是一种气态、可压缩性流体,其计量涉及流量、温度、压力、组分等多参数的测量。作为一次检测仪表的流量计本身仅能检测工作状态下的天然气体积量,无法给出标准状态下的天然气体积量,给天
Gas transmission difference is the difference between gas purchase volume and gas sales volume. For gas companies in the middle reaches, they are the amount of gas purchased from upstream gas companies and the amount of gas sold to downstream gas companies. First, the transmission error analysis 1. Measurement error (1) unity of the unit As natural gas is a gaseous, compressible fluid, the measurement involves flow, temperature, pressure, composition and other multi-parameter measurement. As a test meter flow meter itself can only detect the working state of the volume of natural gas, can not give the standard state of the volume of natural gas to the day
