  • Apparatus and method for volume and mass estimation of a multiphase fluid stored at cryogenic temperatures
    Patent number: 9513155
    Abstract: An apparatus and method estimate fluid mass in a cryogenic tank that holds a multiphase fluid comprising a liquid and a vapor. The apparatus comprises a level sensor, a pressure sensor and a computer. The level sensor provides a parameter representative of a level of the liquid. The pressure sensor provides a pressure signal representative of vapor pressure inside the cryogenic tank. The computer is operatively connected with the level sensor and the pressure sensor to receive the parameter and the pressure signal, and is programmed to determine the level from inputs comprising the parameter, to calculate a first volume of the liquid from inputs comprising the level, and to calculate a first mass of the liquid from inputs comprising the first volume and the pressure signal.
