Some products packaged in bags, bottles, cans, etc. need to be loaded first and then weighed on a weighing scale to ensure that the net weight of the products inside the packaging matches the weight indicated on the packaging. However, due to changes in the mechanical and material characteristics of the loading machine, the weight of the goods loaded into each packaging container may change, resulting in overweight or underweight of the goods. Excessive overweight affects the efficiency of the enterprise, while underweight may lead to complaints from users, affecting the reputation of the enterprise.

If the goods are loaded in liquid, powder, or small particle form during the packaging loading process, the real-time measurement value of the weighing scale can be used to automatically control the loading process to ensure that the weight of the goods marked on the packaging is not too much overweight.
