标准表法气体流量标准装置的流场分析

摘要

Working theory and basic construction on standard facilities of gas flow for master meter method are given. Flow field in piping system has been numerically simulated. Analysis has been done with the influence on distribution of flow. Master meters can be chosen according to the reasonable proposal. All of these are significant for designing and using standard facilities with master meters.%介绍标准表法气体流量标准装置的工作原理与基本结构，通过对装置管路进行流场数值模拟，分析管路布局对流量分配的影响，得出了合理选择使用标准表的方案。对标准表法气体流量标准装置的前期设计及后期使用具有参考意义。
