Using the analyzer the average density and water percent of water-cut

gas-cut oil can be measured based on different absorption degrees of low energy photons for the media with various density and composition. The measurement accuracy is not influenced by the mixing state of oil and water

the gas content and the properties of oil. The measurement range of water percent is 0-100%. An 241Am source is used to irradiate the coned silver sheet to form a realistic photon source. The escape peak of 50 keV gamma rays is correctly dealt with and a newly derived equation is utilized to make calculations

thus the standard error of water percentage measurement is reduced to equal or less than 1.1%.
