Propellants for space vehicles were gaged by various techniques and instruments, none of which was satisfactory; General Dynamics/Astronautics established feasibility of using RF technique to measure quantity of remaining liquid propellant; technique is based on 2 characteristics of propellant tankage, shape of tank and dielectric properties of propellant; analyses performed on cylindrical and spherical propellant tanks to establish basis for selection of proper mode (electric and magnetic field configurations) of operation of cavity; results of measurements verified predictions and established feasibility of technique.
