GWA Loss-in-weight auger fillers utilise three precision, totally sealed stainless steel loadcells that are integrated between the filling head and the main support pillar. These loadcells monitor the actual weight of the product within the auger filler hopper as it decreases during a discharge. Therefore the actual required weight per discharge can be determined be lost weight within the hopper.

One big advantage of loss-in-weight systems, is the elimination of filling inaccuracy that can be brought about through product-in-flight experienced with traditional weighing systems. On form fill & seal applications, it is also possible to now use long augers and funnels within the bag forming tube and still achieve a weight controlled fill. Previous filling systems with long auger and funnels operated only volumetrically, and could produce significant weight errors on larger fill weights.

Use of directly coupled advanced specification motors & amplifiers gives the optimum control and performance of filling accuracy. The lack of clutches, brakes, belts and chains eliminates expendable items, and thus reduces maintenance to an absolute minimum. This can dramatically increase the long term reliability.
