Belt Scales

A belt conveyor scale is a device that continuously measures bulk material as it moves along a conveyor. The system requires two general parameters to operate.  First it needs to know the weight of the material being moved along the conveyor belt and second it needs to know the speed at which it’s moving along the conveyor belt.  The weight of the material on the belt is determined by weighing a section of conveyor belt loaded with material and then subtracting the average weight of the unloaded belt.  The speed at which the material is moving is determined by measuring the speed of an idler or wheel in contact with the conveyor belt.  The weight and speed are combined to give a running total and a rate of flow of the material. The correct operation of the scale system requires the components to be installed properly, periodically calibrated, and suitably maintained.

Bulk Pro Systems, LLC manufactures many different models of belt scales customized to fit your application. Our models consist of single idler process control belt scales to multi-idler high accuracy belt scales with accuracy’s from plus or minus 1% to plus to minus 0.125%.
