Abstract: A weighing system for weighing a vehicle such as a torpedo car containing a body of molten metal where the center of gravity of the body of molten metal may shift in an uncontrollable manner within the vehicle and which vehicle has a first group of axles at the forward end thereof and a second group of axles at the rearward end thereof with each axle having at least two wheels thereon and wherein the axles of each group are symmetrically spaced about a center through which the load is applied to the axle group. The weighing system includes first and second weighing devices. The weighing devices are located so that the first weighing device engages the wheels of a fraction of the axles of the first group of axles and the second weighing device engages the wheels of a fraction of the axles of the second group of axles.
