2135183 9325638 PCTABS00028 An arrangement for adding an odorant to a consumer gas which is distributed to a consumer site, in order to indicate to people in the vicinity of the risk of fire, explosion, poisoning, suffocation or some other danger, should consumer gas leak into the surrounding atmosphere. The odorant is dissolved in a condensed vehicle gas in a pressure vessel (3), to obtain a solution, master gas, which includes a liquid phase (6) and a gas phase (7). The consumer gas is diluted with an adapted quantity of the liquid phase of the master gas, which is vaporized prior to being mixed with the consumer gas. To this end, the arrangement includes means (18) for correcting the relationship between the two gas flows during the dilution process with respect to the increase in the concentration of odorant in the liquid phase (6) of the master gas that results from the decreasing relationship between the quantity of liquid gas and gas phase (7) in the pressure vessel. This provides for extremely accurate metering of the master gas. The invention also relates to a method of adding an odorant to a consumer gas.
