摘要:
A 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 operation, a racheting process is used to avoid the use of spurious weight signals to determine the material weight in the feeder for purposes of properly controlling the discharge rate.
