Gauge Point Calibration, Inc. performs High Definition 3-D Surveys to calibrate a variety of holding tanks, including, upright cylindrical, horizontal, spheroid and spherical tanks, ships, barges and rail-cars. In addition to tank calibrations, High Definition Survey (HDS) systems can be programmed to collect over a million data points in one or more surveys to be used in the calculation of overfill, environmental, mechanical, structural damage and placement of alarm levels. The data can also be used in the design of secondary containment and levee systems.
