摘要
介绍了尿素装置的合成塔、气提塔为何采用γ射线液位计;论述了γ射线液位计测量原理;论述了钴源与铯源不同应用场合下的安装方式、维护注意事项及如何延长放射源的使用寿命的方法;辐射探测器闪烁计数器的特点、安装及维护要点;以及γ射线液位计3种不同的调试方法。
Why in synthetic tower and gas stripper of urea unit radiating level gauge is applied is introduced.The measurement principle of radiating level gauge is explained.The way of installing and maintenance and prolonging life of Co 60 source and Cs 137 source when they apply in different spots is presented.Characteristics and installing and maintenance of flickering counter and three debugging ways of radiating level gauge are provided.
