Abstract:
1. A method for controlling an amount of material transferred in a system having a plurality of material feeds and concurrent material transfer periods, the method comprising steps of: a. providing a receiving vessel coupled to a load sensing element, b. providing a primary material supply to the receiving vessel, c. providing a Target Weight (TW) amount for a primary material, d. providing a secondary material supply comprising a secondary material feed sensing element, e. determining a feed alone time period for the primary material, the feed alone time period beginning at a feed alone time threshold f. beginning to feed the primary material to the receiving vessel via the primary material supply, g. determining the actual feed rate of the primary material, h. starting to feed the secondary material into the receiving vessel as or after the primary material begins feeding into the receiving vessel, and before the feed alone time threshold, i. determining a feed status of the primary and secondary material feeds at the feed alone time threshold, j. ceasing to feed the primary material when the secondary material has an active feed status at the feed alone time threshold, k. resuming to feed the primary material as or after the secondary material feeding stops, and l. feeding only the primary material within the feed alone time period until the TW amount is fed.
