A vehicle has a fuel system that includes a controller that determines when the vehicle is in a refuel mode or a run mode based on a connection of a refuel nozzle to a vehicle connection of the vehicle. The controller controls a fuel pump input selector, a vehicle fuel pump, and a fill/run fuel selector such that fuel is pumped from a storage tank external to the vehicle into a vehicle fuel tank by way of the vehicle fuel pump in the refuel mode, and fuel is pumped to an engine of the vehicle from the vehicle fuel tank by way of the vehicle fuel pump in the run mode.

A system provides a level detector with a multi-axis magnetometer sensor that senses movement of a magnet connected to a float within a vessel. A temperature sensor may assist in compensating for changes to the magnetic field due to ambient temperature. Output from the sensor is provided to a local data processing unit which provides level data to a local display. The local data processing unit sends data through a communications port to a remote system which can track level remotely as well as assimilate and uniquely characterize data from other vessels to provide more accurate level measurement by the local processing unit.

A pressure containment assembly for use with a plurality of sensor assemblies for monitoring a parameter within a pressure vessel is disclosed. The pressure containment assembly includes a primary seal plate to seal against pressure in the pressure vessel and a plurality of passageways to receive the sensor assemblies. The containment assembly also includes a secondary seal cap connected to the process plate and covering the passageways. The seal cap includes a recessed region that is oriented such that, when the seal cap is sealed to the primary seal plate, the recessed region creates a sealed pressure containment chamber.

A storage tank for cryogenic liquid includes an outer tank constructed of a rigid material and an inner tank contained within and spaced inwardly from the outer tank. A supply line supplies cryogenic liquid to a plurality of cryogenic freezers. A fill line having a diameter greater than the supply line allows the storage tank to be filled at a greater speed relative to filling through the supply line and allows the storage tank to be filled while supply cryogenic liquid to the cryogenic freezers. A level sensor processes an impedance to calculate a level of the inner tank and a reporting unit displays the level and may report the level to a remote server.

Mobile cryogenic tank for transporting cryogenic fluid, notably liquefied hydrogen or helium, comprising an internal shell intended to contain the cryogenic fluid, an external shell arranged around the internal shell and delimiting a space between the two shells, said space containing a thermal insulator, the first shell having a cylindrical overall shape extending along a central longitudinal axis (A), when the tank is in the configuration for transport and use, the central longitudinal axis (A) being oriented horizontally, the tank comprising a set of temperature sensors measuring the temperature of the fluid in the internal shell, characterized in that the set of temperature sensors is situated on the external face of the internal shell and measure the temperature of said shell, the set of temperature sensors comprising a lower sensor positioned at the lower end of the internal shell situated below the central longitudinal axis (A), the set of temperature sensors further comprising a plurality of intermediate sensors distributed over two lateral faces of the internal shell on each side of the central longitudinal axis (A), the plurality of intermediate sensors being distributed vertically between the lower end of the internal shell situated below the central longitudinal axis (A) and the upper end of the internal shell situated above the central longitudinal axis (A).

A tank valve system comprises a main valve body, an overfill protection device (OPD), a gauge drive apparatus and a fuel level indicator. The OPD and gauge drive apparatus are configured to both be inserted through a narrow neck of a fuel storage tank prior to connecting the valve body to the neck. The valve body includes a primary fuel channel and a shuttle interface channel. The OPD includes an overfill float driving an overfill shutoff valve for controlling fluid flow from the primary channel into the tank. The gauge drive apparatus includes a gauge float, a shuttle, and an elongated extension body. The gauge float is movable with respect to the extension body between an uppermost position and a lowermost position, thereby driving the shuttle. The shuttle has a gauge actuation portion transportable within the shuttle interface channel to thereby actuate the fuel level indicator.

Provided is a portable gas cylinder including a gas tank having an upper portion, a lower portion, and a collar, the collar including a base secured to the lower portion, a flange extending around and radially outwardly from the base, and a plurality of notches circumferentially spaced around the flange, and a foot ring configured to be attached to the gas tank, the foot ring including a base having an inner surface, an outer surface, a central portion, and a ledge extending around and inward from the central portion, a plurality of circumferentially spaced deflectable longitudinal lock tabs radially outwardly spaced from the central portion for securing the foot ring to the tank, and a plurality of circumferentially spaced rotational lock tabs radially outwardly spaced from the central portion.

A closure is configured for use with a portable cryogenic container or dewar, such as a dry vapor shipper (DVS). The closure has advanced insulating properties which enhances cryogen residence time and also minimizes negative effects on residence time when the dewar is placed on its side, such as during shipping. The closure includes a gas vent in the form of a fluid passage which is particularly sized to minimize thermal leakage and located away from the closure-to-neck interface. Embedded electronics can detect, record, and/or communicate information pertinent to a condition of the storage container in which the closure is installed.

A type IV conformable pressure vessel is provided comprising an elongated folded tank and a valve assembly configured to pass fluid into and out of an interior of the tank through first and second filling couplers directly connected to a respective first and second end of the tank. The tank has at least two chambers for the storage of fluid. The valve assembly receives fluid from an external source, selectively provides the external fluid through a Venturi nozzle into a mixing chamber, recirculates fluid from the second end of the tank into the mixing chamber, and delivers the mixture of the recirculated fluid and the external fluid to the first end of the tank.

A gas cylinder monitoring device (34) for use with a valve (18) for controlling the flow of gas from a cylinder (14). The valve (18) has a valve body (20), and the device comprises an ambient temperature sensor (38) to measure the ambient temperature (TA), a valve body temperature sensor (36) to measure the temperature (TV) of the valve body, and a processor (42). The processor (42) operates to process a compensated temperature (CT) calculated from the difference between the measured valve body temperature (TV) and the ambient temperature (TA) over time (t). A flow-rate (FR) of the flow of gas from the cylinder and/or the pressure (P) on the gas is determined.
