Abstract (en)
[origin: US2021278047A1] 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.
