A cryogenic liquid quantity gauge for low-g application is described, named the Compression Mass Gauge (CMG), operates on the principle of slightly changing the volume of the tank by an oscillating bellows. The resulting pressure change is measured and related by thermodynamics to the volume of vapor in the tank, from which the volume of liquid is computed. The mathematical model of propellant tank with slight volume compression process is built. The mass transfer and heat transfer models among gaseous proportion and cryogenic propellant are projected in order to obtain the variation laws about the parameters, such as pressure and temperature in the gaseous proportion, propellant flux of volatilization, tank wall temperature and so on. Differential equation group is comprised of actual gas state equation, conversation of energy equation, mass and heat transfer equations. The differential equation group is calculated by the means of four steps Runge-Kutta Method. The effect of the compression volume and propellant flux of volatilization to the parameters in gaseous proportion is discussed.
