对JJG1003—2005《流量积算仪检定规程》一般气体流量温压补偿密度问题的一点探讨

Approach to density in temperature and pressure compensation for general gas flow in Verification Regulation for Flow Intergration Meters,JJG 1003-2005

JJG 1003—2005《流量积算仪检定规程》附录B中计算气体标准体积流量的表达式是两个,在制作流量积算仪或流量积算模块时按照这个思路建立数学模型,会增加一般气体流量温压补偿在具体实施中的复杂性。在建立流量积算仪数学模型时可以简化模型;在使用较复杂数学模型的流量积算仪时可以对有关参数的设定进行灵活地处理。

Mathematics formulas in line with the appendix B in verification regulation for flow interg- ration meters,JJG 1003 -2005, make temperature and pressure compensation for general gas now more complicated in practice. A simple model is presented in the article and parameters setting can be handled with in the applications of flow integrating instrument with more complicated mathematic models.
