摘要
以炼化干气为例,对混合气体的物理状态进行分析,结合容积式流量计、涡轮流量计及涡街流量计等的不同流量特性,计算炼化干气的工况状态密度在偏离设计状态密度不同程度的情况下各种流量计测量结果的偏差变化。
Taking dry gas in refining production as example,the physical state of mixed gas was analyzed and its density variation was calculated while having flow characteristics of volumetric flowmeter,turbine flowmeter and vortex flowmeter considered respectively.
