A automatic loss in weight feeder for discharging a flowable material from a reservoir through a controllable discharge member, including a closed loop controller configured to compare the actual rate at which material is discharged from the reservoir to a desired discharge rate. During the "refill" mode of operation, the desired discharge rate is adjusted as a function of both the density of the incoming material and the current weight of material in the reservoir. During steady-state operation, the discharge rate is adjusted in accordance with, inter alia, short term changes in the actual discharge rate which exceed a predetermined threshold value.
