摘　　要：介绍了蒸汽流量的计算模型和JJG 1003-2005《流量积算仪》规定的蒸汽密度取值方式,分析了流量积算仪采用不同的蒸汽密度求取方式对于流量积算仪检定结果的影响。研究结果说明了变工况条件下检定流量积算仪的必要性。本文对流量积算仪的发展提出建议,以提高流量积算仪在蒸汽流量计量中的准确度。This paper introduces the computational models of the steam lfow and the access ways of the steam density proposed in the veriifcation regulation of flow integration meter JJG 1003-2005. It analyzes the inlfuence of the steam densities accessed by different ways on veriifcation results of steam flow integration meters. The research results show the necessity of choosing different working conditions in veriifcation process of lfow integration meters. The paper puts forward some suggestions for the development of flow integration meters to improve the accuracy of lfow integration meters in the measurement of the steam lfow.
