Selecting a weight controller for your filling or dispensing system
This article explains how to select a weight controller that will accurately control your gain-in-weight filling or loss-in-weight dispensing system. The first section describes one-material filling and dispensing applications for weight controllers. Later sections cover choosing controller features, a control method for handling multiple container sizes, and a host system communications network.
Accurately weighing a dry bulk material as it falls into a container or out of a hopper in a plant environment is no trivial matter. A weight controller provides accurate, repeatable filling and dispensing in such an industrial setting. [Editor's note: Information in this article applies to both multifunction weight controllers [for filling, dispensing, batching, and check-weighing] and filler-dispensers, which also provide weight-based control.]
