Abstract

La présente invention concerne des mesures de niveau d'interface dans un réservoir ou un récipient comprenant différentes couches de matière et, en particulier, des procédés de flottation qui sont en particulier appliqués dans l'industrie minière. Le procédé selon l'invention comprend l'analyse de matière dans un récipient (10) comprenant de la bouillie (11a) et/ou de la mousse (11b) et/ou du gaz et/ou une zone de transition entre la mousse (11b) et la bouillie (11a), à l'aide d'au moins une sonde (12) comprenant une pluralité d'électrodes (12') aptes à être en contact avec la matière (11a, 11b), l'injection et la mesure de courants ou de tensions à travers au moins deux électrodes (12'), et la détermination de la distribution de conductivité pour la matière (11a, 11b) à l'aide de calculs basés sur modèle, qui comprennent la reconstruction d'un profil vertical de conductivité dans la matière (11a, 11b).
