Abstract
A rotary carrousel of a filling installation includes a plurality of filling stations each equipped with a volumetric dispenser (37) whose volume may be varied by varying its dispensing time or the stroke of a piston in a cylinder. At least one of the filling stations includes a balance (36). As a receptacle (39) passes through the filling installation in a filling station equipped with a balance, it is first weighed empty while the corresponding dispenser (37) is filled, and it is then weighed continuously as the material is transferred from the dispenser to the receptacle. The actual weight of material dispensed is determined by comparing the full and empty weights of the receptacle. This weight is compared with a set weight. Any drift which is detected from the set weight can be corrected for subsequent receptacles passing through the filling installation by varying the volume of the material dispensed.
