Abstract
A loss-in-weight feeder for discharging a flowable substance from a reservoir through a controllable discharge member under regulated conditions is comprised of a scale for producing signals representative of the weight of material in the feeder, such weight signals being digitized by a digital converter, the output of which accumulated and fed into a computer and storage device for establishing the actual rate of the feeder, comparing the actual feed rate with a desired feed rate input into the storage device, and developing a correction signal based on any deviation between the actual and desired feed rates and applied to the feeder to adjust the actual feed rate through the discharge member.
