Abstract

L'invention concerne un procédé de détermination d'une quantité d'huile (51) dans un réservoir d'huile (10) d'une turbomachine, le procédé comprenant les étapes suivantes : mesure d'un différentiel de pression entre une première zone (11) du réservoir d'huile (10) destinée à être totalement emplie d'huile (51) et une deuxième zone (12) du réservoir d'huile (10) destinée à être vide d'huile (51)u réservoir d'huile, détermination d'au moins une direction d'une accélération a à laquelle est soumis le réservoir d'huile (10) ; et détermination d'une quantité d'huile (51) dans le réservoir d'huile à partir de la mesure du différentiel de pression entre une première zone (11) du réservoir d'huile (10) destinée à être totalement emplie d'huile (51) et une deuxième zone (12) du réservoir d'huile (10) destinée à être vide d'huile (51), ladite quantité d'huile étant corrigée à partir de ladite moins la direction de l'accélération.The invention relates to a method for determining a quantity of oil (51) in an oil reservoir (10) of a turbomachine, the method comprising the following steps: measuring a pressure differential between a first zone (11) of the oil tank (10) intended to be completely filled with oil (51) and a second zone (12) of the oil tank (10) intended to be empty of oil (51) u tank d oil, determining at least one direction of an acceleration α to which the oil reservoir (10) is subjected; and determining a quantity of oil (51) in the oil tank from the measurement of the pressure differential between a first zone (11) of the oil tank (10) intended to be completely filled with oil (51) and a second area (12) of the oil reservoir (10) intended to be empty of oil (51), said quantity of oil being corrected from said minus the direction of acceleration.
