摘　　要：从分析逐月室外架空、埋地庭院管道燃气温度入手,对济南市无温度补偿家用燃气表的全年燃气表计量误差进行分析。基于逐月室外庭院管道燃气温度,得到逐月燃气表计量相对误差,结合逐月居民生活用气量,得到全年燃气表计量误差,该误差为负值。将燃气表计量总年用气量乘以温度修正系数后,得到标准状态的总年用气量。对于济南市,温度修正系数为1.024。Starting with the analysis of the monthly gas temperature of the outdoor overhead and buried courtyard piping,the annual measurement error of domestic gas meters without temperature compensation in Jinan City is analyzed.Based on the monthly gas temperature of the outdoor courtyard piping,the relative error of monthly gas meter measurement is obtained.Combined with the monthly domestic gas consumption,the annual gas meter measurement error is obtained,which is negative value.After multiplying the total annual gas consumption measured by the gas meter by the temperature correction coefficient,the total annual gas consumption in the standard state is obtained.For Jinan City,the temperature correction coefficient is 1.024.
