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.

A method of collecting a desired end-point weight amount of a material in a collection container in which the desired end-point weight amount can be different each time the method is performed, said method comprising the consecutive steps of: (a) receiving a signal indicating the desired end-point weight amount, (b) calculating a predetermined weight amount by subtracting a fixed offset weight amount from the desired end-point weight amount, (c) conveying the material into the collection container and weighing the material until said predetermined weight amount is collected, (d) conveying for an initial fixed time period an initial incremental weight amount of material into the container, the initial incremental weight amount being less than the fixed offset weight amount, (e) calculating a present weight offset amount by subtracting the then existing weight amount of material in the container from the desired end-point weight amount, (f) calculating a calculated time period by multiplying the initial fixed time period by the quotient of the present weight offset amount and the initial incremental weight amount, (g) conveying additional material into the collection container for said calculated time period, and (h) repeating steps (e) through (g) until the then existing weight amount equals or exceeds the desired end-point weight amount.
