  • Enhanced reference line tank calibration method and apparatus
    Patent number: 9188472
    Abstract: A system for measuring the volume of a tank, including an optical device that emits a laser beam adjacent to a surface of the tank, and a magnetic trolley selectively moveable along the surface of the tank and configured to be remotely controlled by an operator. The magnetic trolley has a linear position sensor in communication with the laser beam to determine the position of the magnetic trolley relative to the laser beam as the magnetic trolley moves on the surface of the tank. A data processor communicates with the linear position sensor to calculate the volume of the tank based at least partially on the position data collected by the linear position sensor.
