Tank Floor Scanning (MFL)

Tank floor scanners use a strong magnetic field to detect indications of pitting and corrosion, while only needing access to one side of the floor surface. This makes tank floor scanning reliable and economical results. Strong magnets in close proximity to the floor will show magnetic flux leakage where there is corrosion or pitting. Sensors will alert technicians in real time when indications occur so they can record and examine further.

As with other forms of map scanning, the entire surface is scanned in a grid. Reported and recorded indications and areas of concern are later subject to ultrasound review to verify the wall loss, pitting, and other corrosion indications.
