FIELD: physics.
SUBSTANCE: system (10) for estimating fluid flow rate supplied from tank (20, 21), comprising measuring means (17, 22, 23) configured to measure level of fluid in tank (20, 21), characterized in that it comprises means calculation of fluid medium flow rate using sigma-point Kalman filter, wherein said calculation means comprise means (16) for obtaining coarse fluid flow rate, as well as correction means (18) associated with the receiving means and with the measurement means and configured to correct the coarse flow obtained by said production means (16), depending on the level measured by said measurement means.
EFFECT: invention also relates to a method implemented by such a system.
