  • Patent number: 10247362
    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.

  • Patent number: 10228091
    Abstract: The invention relates to a valve for a pressurized fluid cylinder comprising a member for manually controlling a flow-regulating member, a sensor for detecting the position of the member for manually controlling the regulating member, a data acquisition, storage, and processing member, and a display for information relating to the fluid flow and/or pressure imposed by the regulating member and/or the valve use mode, wherein when the manual control member is disposed in an intermediate position between two respective adjacent values of the flow and/or pressure of the fluid allowed to pass from the upstream end to the downstream end, the data acquisition, storage and process member is designed to suppress the display information.

  • Publication number: 20170002983
    Abstract: 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.
