压力容器内液面的准确测量是多年来未能解决的一大难题。雷达液位仪的开发应用不仅解决了压力容器内液位的测量问题,也为其它行业物位的测量开辟了更广阔的前景。介绍了雷达液位仪的原理、构造,分析了现场实际应用中出现的问题及解决的办法,认为对现用的储存液化石油气、丙烯等产品罐可在不停产、不动火的情况下安装雷达液位仪表。经现场的多次试验调试,总结了一套较完整的安装应用技术,同时对罐外安装的标定、计量误差、罐内外温差等问题也进行了全面的分析,并提出了解决办法。
The accurate measurement of the liquid level in a pressure vessel is a major problem that has not been solved for many years. The development and application of the radar level gauge not only solved the problem of measuring the liquid level in the pressure vessel, but also opened up a broader prospect for the measurement of other industries. The principle of radar level gauge is introduced and its problems and solutions in practical application are analyzed. It is considered that the existing tanks for liquefied petroleum gas, propylene and other products can be kept in production without stopping Install radar level gauge. After many tests on site, a set of more complete installation and application technologies has been summarized. At the same time, problems of calibration of installation outside the tank, measurement error, temperature difference between inside and outside the tank have also been analyzed comprehensively and solutions have been put forward.
