APPARATUS AND METHOD FOR IMPROVING THE ACCURACY OF A LOSS-IN-WEIGHT FEEDING SYSTEM Abstract of the Disclosure A control for loss-in-weight feeders which decreases flow error during refill of the feeder hopper. The weight range (empty to full capacity) of the hopper is divided into weight increments. Samples are taken of the hopper weight during discharge and refill, and each sample is assigned to a weight increment. During discharge, a scale factor related to the density of material in the hopper is computed, assigned to a weight increment and stored in memory; and the hopper feed screw is driven at a speed proportional to the computed scale factor. During refill, the stored scale factors are retrieved from memory and the hopper feed screw is driven at a speed proportional to the stored scale factors; but no additional scale factors are calculated.
