Abstract
The present invention is directed to methods and apparatus for controlling the quanatity of material dispensed from dispensing systems. In one aspect of the present invention, a dispensing system includes a weight scale upon which material is dispensed from a dispensing system during a calibration routine. The weight of the dispensed material is determined and compared with a target weight. If the weight of the dispensed material varies from the target weight by more than a predetermined amount, then characteristics of the dispensing system are adjusted, and the calibration routine is repeated.
