摘要
主要介绍空分装置中液氧、液氮流量采用涡街流量计测量的方法,探讨使用现状的优劣点,对不能测量较大流量以及涡街流量计小信号切除量较大的问题进行相关应用分析,对空分装置在产品核算、经济效益分析、可靠运行的方面具有一定帮助。
Measuring liquid oxygen and nitrogen with vortex flow meter was analyzed, and the vortex flow me- ter＇ s incapability in measuring high and low flow signals were discussed so as to benefit product accounting, e- conomic benefit assessment and reliable operation of air separation unit.
