Abstract

Ce dispositif de mélange comprend une entrée de gaz traceur (2), une entrée de gaz porteur (6), une chambre de mélange (10), une sortie de mélange (9), une première vanne (11) entre l'entrée de gaz traceur (2) et la chambre de mélange (10), une deuxième vanne (12) entre l'entrée de gaz porteur (6) et la chambre de mélange (10). Ce dispositif de mélange comprend en outre une unité de pilotage (20) configurée pour piloter la première vanne (11) suivant une première séquence d'ouvertures et de fermetures, et la deuxième vanne (12) suivant une deuxième séquence d'ouvertures et de fermetures, de façon à obtenir un mélange ayant une concentration volumique prédéterminée du gaz traceur dans le gaz porteur.
