ABSTRACT:
A container-filling-and-weighing device having a frame and a connected weighing member. A first single point load cell is connected near the top of the weighing member and attaches to the frame. A second single point load cell extends from near the bottom of the weighing member and attaches to the frame. The load cells are preferably parallel, essentially identical and intersected by a vertical line. Any nonvertical force applied to the upper load cell is offset numerically by an equal and opposite nonvertical force applied to the lower load cell. These disparities are removed by averaging the numerical output from each load cell.
