In most devices presently in use, radiation sources all of the same energy output and half-life are utilized. The greater the amount of the contents in the tank, the larger the attenuation will be of the detected radiation. It is known to measure the quantities of the liquid within a tank, by using radiation sources positioned at the tank and a detector positioned for receiving radiation from the sources which has passed through the contents of the tank and is thereby attenuated. This invention relates to a method and apparatus for determining the quantity of material in a tank, such as a satellite fuel tank, by radiation detecting means. ![]()
