7. A method for transferring an odorant to an odorant chamber for odorizing a natural gas in a gas line, the method comprising:
venting the chamber to the atmosphere;
creating a pressure differential between an odorant source connected to the chamber and a receptacle connected to the chamber so that the odorant flows from the odorant source and into the chamber;
detecting that the odorant is flowing from the chamber to the receptacle;
stopping the odorant from flowing into the chamber;
closing the chamber off from the atmosphere;
providing a wick disposed within the chamber; and
transferring the odorant from the chamber to the gas line by way of the wick.
