摘要为研究在天然气实流介质条件下的热式燃气表计量性能,配置了6种不同组成成分的天然气,并以此为介质对现有的热式燃气表进行了计量性能测试。试验中,以一只高精度涡轮流量计的计量结果为标准数据,将关闭燃气组分识别功能的热式燃气表计量数据、开启燃气组分识别功能的热式燃气表计量数据与标准数据进行了比较。试验数据表明,开启燃气组分识别功能后的热式燃气表计量结果最大计量相对误差减小至7%内。

Abstract：To make sure the metrological performance of thermal mass gas meters under different component nature gas measurement conditions, an experiment has been designed and six kinds of nature gas with different components have been used as measure media. The measurement results of a roots flow meter is set as the standards, and the measurement results of thermal mass gas meter are compared with the standard results. The experimental data showed that the maximum relative error of the measurement result of the thermal gas meter is reduced to 7% after the gas component identification function is turned on.

Key words： metrology thermal mass gas meters practical gas flow metrological performance
