The invention relates to a valve for a pressurized fluid cylinder comprising a draw off circuit, a data acquisition, storage, and processing member, at least one display and a pressure sensor for measuring the pressure within the storage space of a fluid cylinder connected to the valve. When the variation of the signal representing the fluid pressure measured by the pressure sensor is greater than a specific draw off threshold, the data acquisition, storage and process member is designed to detect the drawing off of gas and, in response, to control the displaying on the display of at least one item of information concerning the draw off. |
