The invention relates to a gas container equipped with a gas distribution valve having an electronic device for measuring gas autonomy. Flow selection means allow a desired gas flow to be selected. The electronic device includes a pressure sensor. Signal processing means allow gas autonomies to be determined on the basis of the pressure signal and of the selectable gas flows. A selection component cooperates with the signal processing means in order to successively display, on data display means and in response to successive digital activations by the user of the selection component, the various selectable flow values and the various corresponding autonomies, with each flow value being simultaneously displayed with a corresponding autonomy.

The present invention relates to a hydrogen gas composition comprising specific gas contaminants at threshold limit values (as listed in the ISO 14687:2019 standard). The invention also concerns a metal cylinder such as an aluminium cylinder comprising a hydrogen gas composition according to the invention.

The hydrogen gas composition of the invention may be used as a calibration composition and/or quality control composition for controlling hydrogen fuels.

A sensor assembly is positioned on an exterior of a tank to measure a fluid level within the tank. The tank is modified to include a surface feature and the sensor assembly is slotted within that surface feature. The sensor assembly includes a sensor device and a control circuit configured to drive the sensor device and evaluate readings to determine the fluid level. The sensor assembly further includes a communications interface to enable communication with a management system via a communications network. The management system can store information (e.g. fill status) related to the tank and additionally communicate with vendors or end users to coordinate resupply.

The invention relates to a pressure vessel (1), comprising a vessel body (3), wherein at an upper end of the vessel body (3) an end region (2) is formed in one piece with the vessel body (3), which has an opening (O), and a fastening structure (9) for a valve (6) formed on the inside of a wall (2.1) surrounding the opening (O) of the end region (2). According to the invention, two outflow openings (SO) are formed opposite each other in the wall (2.1) surrounding the opening (O) of the end region (2).

The invention relates to a pressurized gas container, in particular a gas cylinder, having an internal volume for gas storage, a fluid-distributing valve, a pressure sensor and microprocessor-based control means. The microprocessor-based control means are configured to detect filling of the gas container with gas, by comparing said at least one pressure value measured by the pressure sensor with at least one predefined and stored reference pressure threshold value; then to initiate a timer on the basis of a detection of filling of the gas container with gas; and to trigger a warning when the timer exceeds a given period calculated from the initiation of the timer.

A system and a method for filling a tank are provided. The tank filling system includes tanks that are filled with predetermined fluid and a manifold that is coupled to each of the plurality of tanks in a communication manner. A first flow passage is connected to a first inlet of the manifold to supply the fluid to be filled into the plurality of tanks to the manifold and a second flow passage is connected to a second inlet of the manifold spaced apart from the first inlet of the manifold by a predetermined distance to supply the fluid to be filled into the plurality of tanks to the manifold. A controller opens and closes the first flow passage and the second flow passage.

An integrated carrier for a calibration gas storage cylinder is provided. The integrated carrier may comprise a carrier base, a carrier cap, and carrier beams. Each of the carrier beams may comprise a cap-end and a base-end. A cap-end bolt may be threaded into the cap-end and a base-end bolt may be threaded into the base-end. The carrier cap may comprise a laterally-oriented keyhole access opening that may be configured to mate with the cap-end of the carrier beams and the carrier base may comprise an axially-oriented bolt passage that may be configured to pass the base-end bolt of the carrier beams. The carrier base, the carrier cap, and the carrier beams may collectively define a cylindrical receiving space that may include the calibration gas storage cylinder and may define a longitudinal containment height. The carrier base may comprise a regulator-receiving depression and a detector-receiving depression that may each comprise open sides facing the carrier cap.
