The metering device, particularly for liqueur-like additives for bottled beverages, comprises a rotary apparatus 7 equipped with metering stations 19 distributed on its periphery. Each station comprises a dispensing spout connected via a tube 32 to the exit of an individual metering pump 19. Each pump 19 comprises a flexible tube 22 whose end openings are equipped with an inlet valve 24, 26, 28, 31 and an outlet valve 23, 26, 27, 29. A pusher 46 is movable between an expulsion position in which it gives rise to a gripping of the flexible tubular body 21 in a region located between the valves, and a suction position in which it allows the flexible tubular body 21 to resume elastically a position of rest. The pushers 46, which can be adjusted by micrometer screws 56, are actuated by a central cam immobilised in rotation with respect to the frame. Use for increasing the precision of metering, the ease of cleaning, reliability in respect of seizing and liqueur stagnation. <IMAGE>
