Magnetic Flux Leakage (MFL)

Floormap 3Di

Building on the success of the Floormap3D with STARS top and bottom defect discrimination, continuous research and development has resulted in the most advanced Magnetic Flux Leakage MFL tank bottom inspection scanner theFloormap3Di. The new system introduces:

  • MFLi (intensity) - advanced search and verification tool
  • Dynamic cursor - advanced defect sizing and classification tool

Together these innovative features achieve significant advances in tank inspection corrosion measurement, with the potential to reduce inspection times and significantly enhance the quality of a tank inspection. This enables tank engineers to determine the optimum repair strategy and improve the outcome of Fitness For Service (FFS) assessments, Remaining Life Assessment (RLA), and Risk Based Inspection (RBI) programs.

High Productivity And High Accuracy Tank Inspection

The Floormap3Di has a wider scan width than previous models capable of scanning up to 1440 m2 per day, this is irrespective of the number of indications found.

The software guided mapping process encourages the most efficient plate coverage, and helps ensure the maximum area is scanned reducing the chance of missed corrosion. The high resolution MFL sensor head coupled with advanced signal processing, and new defect classification tools significantly improves corrosion detection and sizing capability over previous generation systems.


The Floormap3DiM model adds free scan and a stop on defect mode, which bring together the advanced defect detection capability of our Floormap systems with simple to use operation of the MFLi3000.

The Floormap3DiM has a unique Real Time Scan view that displays the MFL signal response whilst scanning, and the latest MFLi defect analysis view for evaluation at the end of each scan. An innovative reverse drive mode allows the technician to retrace the scan, easily locating areas of interest and significantly reducing prove up time.
