The recorded flux leakage data must be displayed in a manner that allows analyst to quickly detect and identify corrosion defects and pipeline features such as welds, offtakes, and valves. When MFL tools were first introduced, strip chart recordings quickly became the most common display method. Once the data are on paper, this display method enables a fast detection of defects by a skilled analyst. This method is still preferred by some pipeline companies.

More recently, the advent of computer systems has led to new data display and analysis techniques. Computer system can easily handle the large amount of data associated with pipeline inspections. A typical example is the implementation of a pseudo-color data display programs.

Once defects are identified, the data can be further analyzed to determine defect type, geometry, and severity. Additional data display methods are used including during this process include

detailed strip chart displays
pseudo color topographical maps
three-dimensional black-and-white wire-frame maps
three-dimensional color wire-frame maps.
