Abstract
A method and apparatus of collecting a desired end-point weight amount of material first conveys the material into the collection container until a predetermined weight amount is collected. The predetermined weight amount is less than the desired end-point weight amount by a selected initial weight offset amount. An additional incremental amount of material is next conveyed into the container for a predetermined fixed time period. In doing so, the method and apparatus gauge the particular flow characteristics of the associated flow system. A further additional incremental amount of material is conveyed into the collection container for another time period, the length of which reflects the anticipated flow characteristics of the system, based upon the performance of the system during the preceding period. The method and apparatus repeat this sequence until the then-existing weight amount equals or exceeds the desired end-point weight amount.
