Method and device for filling a tank with pressurized gas

A device for filling tanks with pressurized gas to a target pressure, comprising a pressurized gas source, a transfer pipe, and a computer, wherein:

• the transfer pipe has an end that is adapted and configured to be connected to a tank to be filled, thereby forming an injector having a predetermined injection diameter D1;
• the transfer pipe is adapted and configured to transfer the gas from the source to the tank;
• the transfer pipe is provided with at least one valve;
• the computer is adapted and configured to receive, store and process data;
• the computer is adapted and configured to control a filling of the tank with the gas of the source by controlling the at least one valve;
• the computer is adapted and configured to receive or calculate a ratio of a length L of the tank to be filled to a diameter D of the tank to be filled;
• the computer is adapted and configured to compare L/D with a first threshold S1, and as a function of said comparison, modify or signal a need to modify at least one parameter associated with filling the tank to be filled, said at least one parameter being D1, a flow rate Q of gas to be transferred from the source to the tank to be filled, of both D1 and Q.
