Title (EN) METHOD AND DEVICE FOR DETERMINING AN AVERAGE PARAMETER OF A FLUID IN A CLOSABLE CONTAINER
(FR) PROCÉDÉ ET DISPOSITIF POUR DÉTERMINER UN PARAMÈTRE MOYEN D'UN FLUIDE DANS UN RÉCIPIENT POUVANT ÊTRE FERMÉ
Abstract:
(EN) A method for determining an average temperature of a fluid in a closable container (1) comprising: providing a duct (4) with first opening (11a) and second opening (11b), positioning a flow preventing element (7) in the duct (4), positioning a density sensor (3) or first pressure sensor (3) inside the duct (4) or container (1), attaching the duct (4) to a container outside wall, stabilizing a temperature of the duct wall (10) to a constant reference value, determining a difference between a first pressure of the fluid on one side and a second pressure of the fluid on the other side of the flow preventing element (7), measuring a local density of the fluid by the density sensor (3) and/or a local pressure by the first pressure sensor (3), and deriving the average temperature from the local differential pressure, the local density and the reference duct temperature.
(FR) L'invention porte sur un procédé pour déterminer une température moyenne d'un fluide dans un récipient pouvant être fermé (1), qui consiste à : utiliser un conduit (4) ayant une première ouverture (11a) et une seconde ouverture (11b), positionner un élément d'arrêt d'écoulement (7) dans le conduit (4), positionner un capteur de densité (3) ou un premier capteur de pression (3) à l'intérieur du conduit (4) ou du récipient (1), attacher le conduit (4) à une paroi extérieure de récipient, stabiliser une température de la paroi de conduit (10) à une valeur de référence constante, déterminer une différence entre une première pression du fluide sur un premier côté et une seconde pression du fluide sur l'autre côté de l'élément d'arrêt d'écoulement (7), mesurer une densité locale du fluide au moyen du capteur de densité (3) et/ou une pression locale au moyen du premier capteur de pression (3), et obtenir la température moyenne à partir de la pression différentielle locale, de la densité locale et de la température de référence de conduit.
