摘　　要：原油含水含气分析仪是利用介质对某一低能γ射线的吸收而引起强度的变化 ,与介质的质量吸收系数和密度有关外 ,还与组成介质的成份和各种成份所占的比例有关。通过测量γ射线穿过被测介质前后强度的变化获取有关信息 ,经过分析与计算 ,得到组成介质的各种组份的含量。再输入流量计信号 ,实现原油在线连续自动测量。这种仪表是核机电一体化的高科技产品 ,保证了较高的测量精度 ,避免了人工计量工作量大、计量误差大的现象 ,实现了分队计量 。Water-cut/void-fraction analyzer for crude oil is based on the principle that the intensity of a certain low-energy gamma ray that passes through a medium varies with the components of the medium and their ratio as well as with the medium's mass-absorbing coefficient and density.The contents of various components of a medium can be found out by analyzing and calculating the data obtained by measuring the different intensities of the gamma ray before and after it passes through the measured medium.On this basis,Continuous on-line automatic measurement of crude oil can be achieved by putting in the signals from flowmeters.
