Abstract
Procédé de détermination en temps réel du niveau de remplissage d'un réservoir (1) cryogénique destiné à contenir un mélange diphasique liquide-gaz dans lequel est calculé à chaque pas de temps (t, t+ Deltat...) pour le liquide et éventuellement pour le gaz au moins l'un parmi : le niveau, le volume ou la masse contenue dans le réservoir (1), le procédé mesurant à chaque pas de temps le différentiel de pression (DP=PB-PH) entre les parties haute et basse du réservoir et au moins une des pressions (PH, PI) dudit différentiel, caractérisé en ce que le procédé :- calcule par un modèle thermique à chaque pas de temps (t, t+ Deltat...) les températures moyennes du liquide (TI) et du gaz (Tg) dans le réservoir (1) à partir du différentiel de pression (PB-PH) mesuré et d'au moins une des pressions (PH, PI) dudit différentiel ,- calcule l'évolution dans le temps (t, t+ Deltat...) au moins la masse volumique du liquide (pl) à partir la température moyenne du liquide (TI) et des pressions (PH) (PB) dans le réservoir,calcule le niveau de liquide (hl) dans le réservoir (1) en appliquant la loi générale de l'hydrostatique au liquide du type : dP=- rhol.g.dhl à partir de la masse volumique de liquide (pl) calculée (avec dP la variation de pression du liquide, pl la masse volumique du liquide, g l'accélération terrestre, et dhl la variation de hauteur du liquide).
