Abstract
The total weight of material loaded into a floating barge is determined with high accuracy automatically. Human and other error factors are eliminated. Before and after loading, the angle of list of the barge in the port-starboard plane and the angle of trim in the fore-aft plane, together with the distance from the water surface to a fixed overhead structure and the distance from this structure to a fixed point on the barge deck are measured. Using the known barge geometry and the above measurements before and after loading, a computer calculates the change in the volume of water displaced due to loading the barge and by using Archimedes' principle and then calculates the payload introduced into the barge.
