摘要： System and methods for measuring the density, level, or interface position of a fluid or fluids in a vessel using gamma-ray backscatter are disclosed. The gamma-ray instruments disclosed may account for vessel wall buildup or deterioration. Methods disclosed herein include detecting gamma rays backscattered by a fluid from a gamma-ray source positioned proximate to a vessel with at least two gamma-ray detectors positioned proximate to the vessel and to each other; and determining a density, level, or interface value of the fluid based upon intensities of backscattered gamma rays received by the two or more gamma-ray detectors; wherein the vessel wall is subject to at least one of buildup and deterioration. The density, level, or interface may be a function of a ratio of the intensity of backscattered gamma rays received by two or more of the detectors.
