ABSTRACT:
Disclosed is a system and method for the high-speed, cyclic batch weighing of a flowable material in which variations in initial scale weight are automatically compensated for. Measuring cycle time is minimized by overlapping the time required to achieve scale stability prior to tare with the material discharge time. Tare weight is automatically measured during a weighing cycle following material discharge while the weight container is open to provide a residue compensation output signal.
