Abstract: Method for determining the initial pressure of a pressurized gas tank to be filled from a dispensing station, the dispensing station comprising a filling line including in series a pressurized gas source, a heat exchanger, and a dispenser, the dispensing station also comprising a bypass line on the filling line around the heat exchanger, the method comprising the following steps: a step of transferring a gas flow from the gas source or the heat exchanger to the dispenser via the bypass line, a step of reading an initial pressure in the tank to be filled as a function of a pressure measured on the filling line.

Abstract: Method for preventing or limiting icing of a station for distributing a pressurized gas, the station comprising a filling line having in series an end connected to a source of pressurized gas, a first heat exchanger for cooling a gas flow coming from the source, and a distribution terminal intended to distribute the cooled flow to a reservoir to be filled, the distribution station also comprising a bypass line of the filling line at the first heat exchanger, the method comprising a step of transferring a flow of relatively hot gas to the distribution terminal via the bypass line, the flow of relatively hot gas being at a temperature higher than a predefined temperature at the outlet of the first heat exchanger.
