摘　　要：叙述了硝酸磷肥装置中液位测量仪表的应用及液位测量仪表应用过程中所存在的问题及改进办法。选用EJA系列智能型电动法兰式液位变送器代替原吹气式液位测量仪表及浮筒液位计 ,介绍电动法兰式液位变送器的特点 ;选用液位测量仪表的原则。该公司选用 5 0余台法兰式液位变送器使用稳定可靠 。The application of liquid level instrumentation in production of nitrophosphate, some existing problems and their countermeasures are described. Through the application of more than 50 sets of EJA serials of intelligent electric flanged liquid level transducer at the company instead of original aerated liquid level instrumentation and float type liquid level instrumentation, a stable, reliable and easily maintainable performance is displayed. Meanwhile the characteristics of the electric flanged liquid level transducer and the selecting principles of liquid level instrumentation are also discussed.
