The Floormap VS2 uses the magnetic flux leakage technique to detect surface and bottom side corrosion on above ground storage tank floors to provide a reliable indication of the floor condition within an economical time frame. The test can be carried out through surface coatings like paint or epoxy etc. The VS2i contains significant improvements in terms of defect positioning, electronic data processing and software manipulation. Additional data from visual, ultrasonic, vacuum box and magnetic particle inspection can be added to the report generating a full fingerprint of the tank
