The
TesTex Falcon Mark II LFET Above Ground Storage Tank Floor Scanning
System is based on the principles of Low Frequency Electromagnetic
Technique (LFET). It is designed to quickly and accurately inspect
ferrous above ground storage tank floors.

The
Falcon 2000 system uses scanners that have 16 or 64 pickup sensors
equally spaced to scan flat surfaces covering 4” (102mm) and
13” (330mm) swaths per pass. A 16- channel/16-sensor scanner
called the Falcon Jr., is used for hard to
reach areas such as sumps/pumps and under heating coils and internal
piping as well as the annular ring. A 32-channel/64-sensor scanner
called the Mark II, is a workhorse used for
intermediate or average sized tanks. All scanners work from one
electronics platform and can be used interchangeably.

Other
methods used for inspecting aboveground storage tanks are Magnetic
Flux Leakage and Ultrasonic Testing. The Magnetic Flux Leakage method
uses permanent magnets, which adds unnecessary weight. It also
requires a cleaner floor surface (sandblast), which causes the
customer to spend additional money for cleaning. In addition,
Magnetic Flux Leakage cannot determine whether a flaw is on the top
surface or bottom surface of the tank floor and cannot test through
coatings. The U.T. method again requires a cleaner floor surface and
is very time consuming due to the lack of surface area which can be
scanned at a time.

Low
Frequency Electromagnetic Technique on the other hand, does not use
permanent magnets, requires minimal floor preparation, is lightweight
(under 30 lbs), and is easy to handle and transport. It tests through
coatings, determines top surface flaws from bottom surface flaws, and
continues to show flaw responses even after the unit has stopped
moving.

The
Falcon Mark II has many packages available based on your inspection
needs. These other packages can include the Hawkeye system for weld
inspection, the Viper crawler system for wall or shell inspection,
and remotely operated scanners for tank roof inspection.
