Abstract
The invention relates to a pressurized fluid cylinder, a member for acquiring, storing and processing data, and at least one data display device. The valve comprises a sensor which detects the position of a manual control member, and a pressure sensor for measuring the pressure inside the storage space of a fluid cylinder. The data acquisition, storage and processing member is designed to: calculate an actual value for the amount of fluid remaining and/or drawn off; calculate a theoretical value for the amount of fluid remaining and/or drawn of on the basis of the regulation performed by the regulating member and measured by the position of the control member compare the actual value based on the measurement of the pressure sensor with the theoretical value; and generate a warning signal if the difference between these actual and theoretical values is greater than a specific safety threshold.
