The AccuRange line scanner is used to develop a system that senses the profile of material within a tractor trailer. In one instance, they profile trucks carrying tree bark mulch.The scanner measures the volume of bark mulch in bulk delivery trucks, replacing manual methods of climbing into the trailer or counting loader bucket-fulls.  The scanner is mounted onto an arch support under which the trucks drive. As the truck passes beneath the scanner, a laser distance profile of the trailer and its contents is created. By subtracting the known "empty" volume of the container, the vendor can easily calculate the appropriate load and price of materials. This scanner system improves overall billing accuracy and can bring a return on investment within one season
