摘　　要：液位测量是核电厂自动控制系统中重要组成部分。为了适应核电厂液位测量的发展,需合理选择液位仪表。通过对在建电厂液位仪表原理的分析,总结出了不同类型仪表在核电厂的用途、选型、安装等应用中应该注意的问题。通过研究与对比,探索了导波雷达液位计在核电厂液位测量中的应用,提出了新的核电厂液位测量方式,对后续项目的液位测量方式有一定的指导意义。Level measurement is an important part of automatic control system in nuclear power plant. In order to adapt the development of level measurement in nuclear power plant, the level instruments are selected reasonably. Through analyzing the principle of level instruments in the power plant under construction, the precautions in use, model selection, and installation of different types of instruments in nuclear power plant are summarized. By means of research and contrast, the application of guide wave radar level meter in nuclear power plant is investigated, and novel level measuring method in nuclear power plant is proposed, these possess certain guiding significance for level measurement mode of subsequent projects.
