A filling device (10) for filling a barrel with a liquid comprises: a before-filling barrel weight measurement means (12) for measuring a weight of an empty barrel (40) before a liquid is filled into the barrel; a deviation calculation means (31) for calculating deviation by subtracting a predetermined before-filling barrel reference weight from the weight of the before-filling barrel which is measured by the before-filling barrel weight measurement means; a liquid filling means (21) for filling a liquid, the weight of which is predetermined, into the before-filling barrel; an after-filling barrel weight measurement means (17) for measuring a weight of the after-filling barrel after the liquid was filled by the liquid filling means; and an after-filling barrel correction weight calculation means (17') for calculating a correction weight in which an absolute value of the deviation is added to the weight of the after-filling barrel weight in the case where the deviation calculated by the deviation calculation means is negative. Due to the above constitution, even when the weight of barrels deviate, a necessary amount of liquid such as beer can be filled into a barrel. |
