The present invention relates to a method, as well as a system, for filling a container with an amount of liquid carbon dioxide (CO.sub.2) which is partially converted into an amount of solid CO.sub.2 into said container, for the purpose of maintaining one or more products, loaded into said container, at a defined temperature, below a defined temperature, or within a defined temperature range, which temperature or temperature range is below environmental temperature. The invention further relates to a method and a system for providing identification and traceability data determining the container and its loaded one or more products, and for enabling the identification of said container during transport to a particular destination.

The invention relates to a method for a communication between a fueling device (2) and a vehicle (4), having the steps of coupling the fueling device to a tank (6) of the vehicle by means of a fuel hose (10), providing pressurized fuel to the fuel hose, varying the pressure on the fuel hose by superimposing a specified base pressure with a pressure sequence in order to modulate a first signal to be transmitted, detecting the pressure being applied to the fuel hose by means of the vehicle, and extracting the first signal to be transmitted from the detected pressure.

Embodiments of the disclosure may include a dispenser for dispensing a liquid. The dispenser may include a measurement chamber configured to receive the liquid, a temperature probe positioned within the measurement chamber, and a capacitance probe positioned within the measurement chamber. The capacitance probe may house the temperature probe. The dispenser may also include a first conduit fluidly coupled to the measurement chamber and configured to deliver the liquid out of the dispenser.

The invention relates to a method and to a device for determining an amount of gaseous fuel, which during a refueling process at a gas station has been transferred into a storage tank via a gas pump (3) and a filling hose (4) connected thereto, wherein in the gas pump (3) of the gas station, a flow meter (F) is provided, which during the filling of the storage tank detects the amount of fuel dispensed. Once the filling is completed, the filling hose (4) is depressurized, and the amount of fuel, which has not been transferred into the storage tank due to the depressurization, is detected, and this amount is subtracted from the amount detected by the flow meter (F).

A calibration device of the present invention includes: a filling vessel 2, accommodated in a measurement housing 1, to the filling vessel 2 a high pressure fuel gas such as hydrogen gas being fed from outside of the measurement housing 1; a scale 3 for measuring a weight of a fuel gas fed to the filling vessel 2; and a control device CU for eliminating an error caused by changing buoyant force from a gas in the measurement housing before and after filling the fuel gas.

A tank device for a tank liquid comprises a pressure vessel with a first chamber for the tank liquid and second chamber arranged in an interior of the tank. The first and second chamber are closed off with respect to each other and are in operative connection via at least one membrane which separates the first and second chambers and is capable of vibration. The tank device further comprises a controllable element for effecting a pressure surge in the pressure vessel, a pressure sensor for detecting a pressure vibration resulting from the pressure surge and a temperature sensor for measuring a temperature prevailing in the pressure vessel. An evaluation device of the tank device is configured to determine a current gas volume in the pressure vessel from a respectively detected pressure vibration and a measured temperature to thereby calculate the mass of the tank liquid.

According to one or more aspects, systems and techniques for hydrogen fueling with integrity checks are provided herein. Communicated parameters measured by on-board sensors of a vehicle may be cross-referenced against calculated parameters measured by sensors of a fueling station. For example, communicated parameters relating to a compressed hydrogen storage system (CHSS) tank of a vehicle to be fueled may be received at different time intervals. Calculated parameters may be calculated based on a mass of hydrogen fuel dispensed by a hydrogen fueling station from a reference point to one of the time intervals and densities of the CHSS tank of the vehicle at respective time intervals. An error may be calculated between the communicated parameters and the calculated parameters. A fueling mode, such as a conservative fueling mode or a non-conservative fueling mode, may be determined based on the calculated error.

Various cryogenic fluid reporting systems are disclosed. In some embodiments, the system comprises a cart with a base and a load cell. The base can receive and support a cryogenic fluid tank and the weight of the cryogenic fluid tank can be applied to the load cell. The cart can include a transmitter configured to transmit a signal indicative of the weight applied to the load cell. The system can include a receiver configured to receive the signal from the transmitter. The system can include a computing system in communication with the receiver. The computing system can include software configured to correlate the signal indicative of the weight of the cryogenic fluid tank to a fill amount of the tank.

A method for determining a filling mass in a thermally insulated container for a cryogenically stored gas includes determining the filling mass using a known container volume and a calculated density of the gas content of the container. A temperature sensor is used for measuring a mixing temperature of liquid and gaseous phases, where the liquid phase is extracted via a first extraction supply line at the geodetically lowest point, and the gaseous phase is extracted via a second extraction supply line at the geodetically highest point. Downstream of the extraction points, after a convergence of the first and the second extraction supply line, the temperature sensor is placed where a complete and thorough mixing of the liquid and the gaseous phase of the gas from the first and second extraction supply line has already taken place.
