Production of gas mixtures. Fluid-mixing metering plant making it possible to obtain a gas mixture in preselected constant proportions, characterised in that it comprises: - a gas transfer line I designed to be built around a constant-volume measuring chamber 3, commanded by a controller as a function of the pressure prevailing therein; - n fluid transfer lines II, each comprising a metering device 12 controlled by a command unit 20; - a mixing collecting system III where all the transfer lines I and II emerge, made up of a heater 26 followed by a buffer vessel 28 where the gas mixture can be drawn off. Application to mixtures starting with at least one liquid fluid under pressure. <IMAGE>
