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.

Abstract: Sensor probes for capacitance-type liquid level sensors do not comprise an acceptable balance between cost, performance and durability for mobile applications. An improved sensor probe is provided. A first electrode comprises two or more first plate sections arranged in angular relationship with respect to each other. A second electrode comprises two or more second plate sections arranged in angular relationship with respect to each other. Spacers are located between the first and second electrodes such that each first plate section is spaced apart in parallel and substantially overlapping relationship with respective second plate sections. Fasteners securely fix the first and second electrodes in position.

Abstract: A method and a system control flow of fluid from a storage tank through a supply line to an end user. The system includes a valve that in its open position allows fluid flow from the storage tank to the end user and closes when the pressure in the fluid supply line drops below a predetermined set point. The storage tank is thereby isolated because the valve prevents fluid from flowing from the storage tank to the supply line when the pressure in the supply line is lower than a predetermined upper limit of the storage tank pressure. An end use that is particularly suited to the present system and method is a fuel storage and supply system for a natural gas powered internal combustion engine.
