雷达液位计、导波雷达液位计和超声波液位计,因其测量准确、非接触式测量、操作简单、维护方便等特点,越来越多的被应用在电厂的各工艺系统。由于3种液位计工作原理相近,应用人员在选择时易混淆不清,本文对3种液位计从工作原理、技术特点、应用选型和安装注意事项几方面进行研究分析,结合在电厂的实际应用经验,给出了选型建议。
Radar level gauge, guided wave radar level gauge and ultrasonic level gauge, because of its accurate measurement, non-contact measurement, simple operation, easy maintenance and other characteristics, more and more are used in the power plant of the process system. As the working principle of three kinds of level gauges are similar, the application staff are confused when choosing. In this paper, the research and analysis of three kinds of level gauges are made from the aspects of working principle, technical characteristics, application selection and installation precautions, The practical application of experience, given the selection recommendations.
