ABSTRACT:
Apparatus for weighing a continuous flow of powder material, including two separate weighing hoppers, a diverting valve for switching the flow from one hopper to the other and a closure valve for emptying each hopper. Each hopper is supported for small vertical movements by a suspension system including two pairs of crossed flexible wires at upper and lower levels, with the intersections of the wires lying on a vertical axis through a load cell which thus senses the gross weight of the hopper and its load. An automatic controller with a register totals the successive recorded gross or live weights of the hoppers and subtracts successive readings of the tare weights.
