Estimating the term…
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.
Pressurized gas container (1), in particular a gas cylinder, comprising an internal volume (2) for storing gas under pressure, comprising:
Container according to either of the preceding claims, characterized in that the microprocessor-based control means (5) are arranged in an electronic device (7) with a digital display (6).
Container according to one of the preceding claims, characterized in that the microprocessor-based control means (5) are configured to determine that filling of the container (1) has taken place when the measured pressure value is greater than or equal to the reference pressure threshold value.
Use of a gas container (1), in particular a gas cylinder, according to one of the preceding claims, to store or to supply a pressurized gas, in particular a medical gas chosen from oxygen or a gaseous mixture of N2O/O2, NO/N2, He/O2, or medical air.
