摘　　要：在成品油输送工艺中,需要对管道中输送的不同油品界面进行检测,以达到分离不同油品,减少混油量的目的。应用在成品油管道中的油品界面检测方法有密度法、荧光剂法、光学界面检测法、超声波界面检测法。介绍了一种基于光学原理的油品界面检测仪(FuelCheck)的检测原理、组成、安装及在国内兰成渝与西南成品油管道上的应用,该界面检测仪的成功应用,提高了混油界面的检测能力,有利于成品油输油管线安全、平稳、高效运行。In oil pipeline transportation, in order to separate two kinds of oil products and reduce the mix quantity, we need to detect the interface between two kinds of products in product oil pipeline. At present, the application of the oil products pipeline in the interface detection method includes density, fluorescence law, optical interface detection, ultrasonic testing interface. We introduce one kind of interface detector which uses the index of refraction to differentiate adjacent batches of refined products, introduce its principle, compose, installation and its use in Lan-Cheng-Yu refined oil pipeline, etc. Due to its successful use, we have improved the ability to detect the interface between two kinds of refined oil products, therefore ensuring the transportation, safely and efficiently.
