摘要
通过分析常用气体流量计的原理及其公式,给出了仪表测量精度的影响因素;运用提出的气体流量计选型流程图,研究了某型柴油机压缩空气减压阀管路的流量仪表选型问题,经过定性对比以及定量计算,并通过实验验证,最终选定的浮子流量计较好地解决了该管路的流量测量问题。
The paper describes the common gas flow meters and their operational principle expressions,the influence facts on characters are introduced briefly as well.With the exhibited flow chart,the selected variable-area flow-meter properly settles the problem on the type selection of flow meters,which is applied to the measurement of a submarine＇s pressure reducing tube.
