摘　　要：由于单炉双塔的工艺设计将初馏塔由正压操作改为负压操作,所以相应的液位仪表的选择也需要做相应的改变,本文阐述了工业萘初馏塔底液位测量的3种常见测量仪表的选择、存在的问题及改进。As the design of the single furnace and double column is from the plus pressure to negative pressure operation, the choice of the level instrument will be changed accordingly. In this paper, the choice, problem and improvement of three types instruments used for level measurement about the bottom of the industrial naphthalene primary distillation column have been described.
