摘要
对热式质量计量技术的发展及在燃气计量领域的应用进行分析。通过分析热式质量燃气表的计量原理(金氏定律测量法、热分布式测量法),总结家用热式质量燃气表的技术特点和应用特点,指出家用热式质量燃气表的准确计量需要对燃气的密度、热导率、动力黏度、比定压热容等的准确感知。对家用热式质量燃气表的市场应用进行分析,认为基于我国天然气气质特点,家用热式质量燃气表当前在我国不适合大规模普及使用。
The development of thermal mass measurement technology and its application in the gas metering field are analyzed. By analyzing the measurement principle of the thermal mass gas meter( Kim ’s law measurement method and thermal distributed measurement method),the technical characteristics and application characteristics of the domestic thermal mass gas meter are summarized. It is pointed out that the accurate measurement of the domestic thermal mass gas meter requires the accurate perception of gas density,thermal conductivity,dynamic viscosity,and specific pressure heat capacity. The market application of domestic thermal mass gas meter is analyzed. It is believed that based on the characteristics of natural gas temperament in China,the domestic thermal mass gas meter currently is not suitable for large-scale popular use in China.
