    2019-3-20 · Belt Scales enable material to be weighed on a conveyor whilst in motion. A Belt Scale differs from a static weighing system, such as a bin weighing system, in that the Belt Scale is required to measure two variables. The first variable is the actual weight on the conveyor belt, and the second variable is the actual belt speed or belt travel.
