ABSTRACT:
The system for evaluating leaktightness is applied to a gas storage device for storing high pressure fuel gas delivered from a filling station via a filler hose connected to the gas storage device, itself comprising pipework and at least one tank, together with at least one check valve disposed between the pipework and the tank. The system comprises a pressure-measuring device that is suitable for connection to the filler hose or to the pipework, a processor device for processing values measured by the pressure-measuring device, and a display device for displaying information supplied by the processor device. The device for processing values measured by the pressure-measuring device includes a device for controlling filling and for suspending filling of the fuel gas storage device from the filling station, a device for controlling the filling flowing rate, a clock, and a unit for comparing the measured pressure relative to predetermined thresholds Siduring periods in which filling is suspended.
