ABSTRACT:
An apparatus for measuring the remaining weight of fuel in a fuel tank on a flying object, comprising a first set of pressure transducers for detecting the level of fuel in the tank and its density and for outputting the corresponding pressure values; another pressure transducer for detecting the absolute pressure in the tank; and a processor unit connected to the respective transducers for receiving pressure information therefrom and for calculating the remaining weight of the fuel utilizing the pressure information and relevant data stored in a memory. The apparatus is substantially smaller in weight and less expensive than any conventionally known apparatus, and has a high degree of accuracy and reliability of performance.
