摘　　要：利用中子背散射技术,研制出一种立罐油水界面中子测量仪。慢中子探测器和中子源组成的探头在储油罐内升降移动,动态扫描不同高度的物料,根据气、油和水的慢中子计数率不同,测定出三相界面的高度;同时,利用计数率曲线可以得到含水率分布曲线,进而测定出立罐的总含油量。The oil-water interface neutron gauge for oil storage tank is developed by using the neutron back scattering technique. The slow neutron detectors move down and up in the tank and scan dynamic ally the material in different height. On the basis of the different slow neutron counting rate of gas, oil and water, the three-phase interface heights are determined. At the same time, by making use of the counting rate curve the water ratio distribution curves are gained , and the total content of oil in the tank are determined as well.
