An assembly is for filling a gas tank for a combustion engine from a gas-filled storage bottle via a filling device arranged between the tank and the storage bottle. The tank has at least one fill valve for liquefied gas, a pressure relief valve for gas in the gaseous state, and an extraction valve for liquefied gas. The filling device has a gas connection for the storage bottle and has a fill connection for the fill valve. For filling the tank, the fill valve is connected via the filling device to the storage bottle, such that, when the fill valve is open, liquefied gas flows from the storage bottle via the fill valve into the tank. During the inflow of liquefied gas, the pressure relief valve of the tank is at least intermittently open. A filling level gauge is provided for indicating a predefined filling level in the tank.

A control method for a hydrogen filling system is provided. A hydrogen filling system (S) includes a vehicle (V) that sends unique information (V, MC) of the hydrogen tank and detected values (T, P) of sensors, and a station (9) that determines a filling mode based on this information (V, MC, P, T), and fills hydrogen to the tank in this determined mode. A station ECU (95) calculates predicted values (T, P) of the temperature and pressure inside of the hydrogen tank during filling of hydrogen based on the unique information (V, MC), continuously confirms whether the detected values (T, P) of the sensors and the predicted values (T, P) match while filling fuel, and in the case of an inconsistency between the detected values and predicted values being confirmed, interrupts filling of fuel in the filling mode determined based on the unique information.

A method of refueling a vehicle tank with hydrogen, the refueling is controlled by a refueling station controller, the method including: connecting the tank to the station, initiating the refueling process, during the refueling monitoring the temperature of the gas inside the tank, establishing a pressure stop criterion for the refueling, based on a pressure category of the tank and the monitored temperature of the gas, the establishing of the pressure stop criterion being based on a lookup in a predefined table of a plurality of pressure stop criteria, during the refueling monitoring the pressure of the gas inside the tank, by the controller comparing the pressure of the gas with the pressure stop criterion and terminating the refueling when the pressure of the gas inside the tank has reached the pressure stop criterion, and disconnecting the vehicle and the refueling station.

A Venturi filling system having a first filling coupler configured to be coupled to a first set of fittings disposed at a first tank end of a tank; a second filling coupler configured to be coupled to a second set of fittings disposed at a second tank end of the tank; and a Venturi assembly that includes: a Venturi mixing chamber, the Venturi mixing chamber communicating with the first filling coupler; a Venturi nozzle configured to introduce a first flow of fluid from a fluid source to the Venturi mixing chamber of the Venturi assembly; and an suction inlet communicating with the second filling coupler and coupled with the Venturi chamber and configured to receive a second flow of fluid originates from the second filling coupler such that the second flow of fluid flows into the Venturi chamber and mixes with the first fluid flow within the Venturi mixing chamber.

Dual level sensing, vacuum monitoring, smart supply cylinders, smart oxygen monitors, and real time data collection functionality are integrated with a cryogenic storage system to improve sample safety and user safety. The dual level sensing system includes two liquid nitrogen level sensors installed into a cryogenic freezer that send redundant level information to a controller. Vacuum monitoring is performed via a gauge, installed on a vacuum port, that communicates data to the controller. The controller further receives level information from supply cylinders and oxygen levels from one or more oxygen monitors. The aforementioned data sources can be integrated into control decisions executed by the controller. In addition, all operational data of the cryogenic storage system is communicated to a cloud-based platform to provide real-time status monitoring, trend analysis, and alarm notifications.

The invention relates to a pressurized fluid cylinder, a member for acquiring, storing and processing data, and at least one data display device. The valve comprises a sensor which detects the position of a manual control member, and a pressure sensor for measuring the pressure inside the storage space of a fluid cylinder. The data acquisition, storage and processing member is designed to: calculate an actual value for the amount of fluid remaining and/or drawn off; calculate a theoretical value for the amount of fluid remaining and/or drawn of on the basis of the regulation performed by the regulating member and measured by the position of the control member compare the actual value based on the measurement of the pressure sensor with the theoretical value; and generate a warning signal if the difference between these actual and theoretical values is greater than a specific safety threshold.
