Falcon 2000 LFET Scanner
The TesTex Falcon Mark II LFET Above Ground Storage Tank Floor Scanning System uses the Low Frequency Electromagnetic Technique (LFET) to quickly and accurately inspect ferrous, above-ground storage tank floors.
The Falcon Mark II has many packages available based on your inspection needs. Falcons can be mounted on our the Viper Crawler system for wall or shell inspection and remotely-operated scanners for tank roof inspection. In addition, Falcons complement other products like our Hawkeye system, which inspects welds, to provide comprehensive tank inspection solutions.
The Falcon 2000 LFET system uses scanners that have 16 or 64 pickup sensors equally spaced to scan flat surfaces covering four inch (102mm) or thirteen inch (330mm) swaths per pass.
A 16- channel/16-sensor LFET scanner called the Falcon Jr., which is shown above, is used for hard to reach areas such as sumps/pumps and under heating coils and internal piping as well as the annular ring.
All scanners work from one electronics platform–a small, modular, PC-based design–and can be used interchangeably. They can be outfitted with an optional encoder and operate from 110/220v or battery packs.
Advantage of LFET Over Competing Technologies
Other methods used for inspecting above-ground storage tanks are Magnetic Flux Leakage (MFL) and Ultrasonic Testing. Magnetic Flux Leakage uses permanent magnets, which adds unnecessary weight, and it requires a cleaner, sandblasted floor surface, which is expensive and time-consuming. 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.
Like MFL, ultrasonic testing requires a cleaner floor surface and is very time consuming due to the lack of surface area which can be scanned at any one time.
Our Low Frequency Electromagnetic Technique (LFET) products does not use permanent magnets, so are lightweight (under 30 lbs) and are is easy to handle and transport. LFET-based tests require minimal floor preparation; it tests through coatings and determines top surface flaws from bottom surface flaws. Moreover, the Falcon LFET scanners will continue to show flaw responses even after the unit has stopped moving.
Our Reporting software generates a tube sheet map for you examine the results of LFET tube inspections and a tank floor map for LFET tank inspections respectively.
