Abstract

Cette invention concerne un dispositif et un procédé permettant de détecter facilement et avec certitude la présence d'un matériau liquide dans un récipient de stockage. Selon la présente invention, un dispositif de détection (100) qui s'utilise dans une unité d'alimentation en matériaux liquides (20) pour introduire un gaz de compression dans un récipient de stockage (22) destiné à fournir un matériau liquide à un utilisateur, se caractérise en ce qu'il comprend un dispositif de détection de phase (jauge de niveau pour liquide (102)) qui détecte l'état de phase du matériau à transporter et qui est transportée à partir du récipient de stockage (22), et un dispositif d'évaluation (104) qui renseigne sur la présence du matériau liquide dans le récipient de stockage (22) en fonction de l'état de phase (augmentation de la substance liquide dans un récipient de séparation gaz-liquide (50)) détecté par le dispositif (102) du même nom.
