Vertical Pipe Weigher – Online weighing of free ﬂowing bulk solids. In many processes it is important to measure the amount and capacity of flowing bulk solids without requiring accuracy of batch scales. Impact scales provide a comfortable approach to applications with free flowing bulk solids, like grain, pellets and granules. They feature the advantage of continuous measurement without interrupting mass flow. Thanks to its well-engineered and robust construction the Vertical Pipe Weigher is best suited for these applications. The dynamic force is accurately measured by a load cell and evaluated. It is proportional to the conveyed mass flow.
