An apparatus for automatically adjusting a preselected volume of material dispensed by a volumetric filling machine into containers to be filled by weight. The apparatus has a scale for sequentially weighing a plurality of containers each containing the preselected volume of material dispensed by the filling machine and sequentially generating an equal plurality of weight signals representative of the weight of the dispensed material in the containers. A microprocessor receives and stores the sequential weight signals and stores them in a memory, and calculates an average weight value. The microprocessor then compares the average weight value to a preselected weight value and generates a correction signal representative of the comparison. A controller responsive to the correction signal adjusts the preselected volume by an amount sufficient to cause the average weight value to be equal to the preselected weight value.
