infeed equipment feeds product to the weigher which then distributes
it in small quantities into 10 weigh hoppers through a dispersion
feeder, radial feeders and pool hoppers.

load cell measures the weight of product in each weigh hopper
and transmits the resulting weight signal to the calculation
unit.
The
calculation unit calculates the total weights of many different
combinations of weigh hopper contents.
The
calculation unit selects the combination which is equal to or
