Abstract: A system and method for more accurately weighing a product on a continuous weigh belt. The system includes a processing element for determining a flow rate and a total weight of the product at a plurality of points on the weigh belt. A length of the weigh belt between product entrance and exit points is divided into discrete measurement units, or “buckets.” The weight of product in each bucket is determined. The total weight of product that has reached the entrance, exit, and one or more intermediate points on the weigh belt is determined by adding the weight of product attributed to all of the buckets that have reached each point. The flow rate of the product at these points is determined based on the weight of the product attributed to the particular bucket at each point and the speed of the weigh belt.

Abstract: A system (1) and method for coating seeds with a treatment liquid, in which transfers of seeds and liquid within the system arc controlled by a control assembly (6) in accordance with selectable operational modes. Some modes involve determining an actual amount of a quantity and/or a subquantity of seeds transferred from a bin (24) based on a change in the weight of seeds remaining in the bin (24), and adjusting the system (1) to account for a difference between the actual and expected amounts. Other modes involve determining an actual amount of a quantity and/or a flowrate of liquid transferred from a tank (750) based on a change in the weight of liquid remaining in the tank (750), and adjusting the system (1) to account for a difference between the actual and expected amounts. Further, these modes can be performed together for even greater redundancy and accuracy.
