γ射线料位计以其独特的优点——不接触测量,而日益广泛地被应用在石油化工、冶金、采矿、建筑材料等工业生产上。它能对高温、高压密封容器或管道内的腐蚀、高粘度、剧毒性的固、液态介质进行料位测量(见图1所示),解决电容式、浮标式、电阻式等料位计无法解决的问题,而且维护方便,可靠性强。但是,由于过量的γ射线 Γ-ray level gauges are increasingly used in petrochemicals, metallurgy, mining, construction materials, and other industrial productions because of their unique advantages—no contact measurements. It can measure the level of corrosive, highly viscous and highly toxic solid and liquid media in high temperature and high pressure sealed containers or pipelines (see Figure 1) to solve capacitive, buoy, resistance and other level gauges. Unsolvable problems, easy to maintain and reliable. However, due to excessive gamma rays
