ABSTRACT:
A system for measuring the density of a fluid in a vessel, the system including: at least one gamma-ray source positioned proximate to the vessel; at least one gamma-ray detector positioned proximate to the vessel, wherein the at least one gamma-ray detector is configured to detect gamma rays backscattered by the fluid from the at least one gamma-ray source; and a translator for converting the detected gamma-ray backscatter to a density value. A method to determine properties of a fluid in a vessel, the method including: positioning a gamma-ray source proximate to the vessel; positioning a gamma-ray detector proximate to the vessel; detecting gamma rays backscattered by the fluid from the gamma-ray source with the gamma-ray detector; determining a density of the fluid based upon an intensity of backscattered gamma rays received by the gamma-ray detector.
