Voler designed, built, and installed a system to measure the volume of mud put in rail cars at the Hylebos Superfund Site in Tacoma, Washington, using an array of lasers. Mud was dredged from the bay and dumped in rail cars for shipment. It had to be measured accurately because of the high cost of waste disposal. We installed the equipment and did extensive custom software to detect the presence of the container, measure the mud with a laser, calculate the volume, display the results on a computer screen, and report the results in a database which was accessed over the on site network.
