Basic Principles

10. Basic Principles of MFL
The following slides demonstrate the basic principles of MFL for the detection of corrosion on tank bottoms as used on the FloormapVS2i …..

11. Basic Principles of MFL
The FloormapVS2i uses powerful
permanent rare earth magnets, which achieve local
magnetic saturation
of the tank floor
plates
Permanent Magnets

12. Basic Principles of MFL
An array of 36 Hall
effect sensors
are mounted
between the
2 magnet
poles
Sensor Array

13. Basic Principles of MFL
The magnetic leakage field is detected by the hall-effect sensors and converted to an electrical signal
The powerful magnet induces a uniform magnetic field close to saturation in the plate
When corrosion is encountered the magnetic field is forced outside the plate

14. Basic Principles of MFL
All MFL signals are filtered, amplified and combined with positional information from the optical encoder before being stored on the on-board computer.

15. Basic Operation – Collecting Data

16. Basic Operation – Collecting Data
The FloormapVS2i must be calibrated on a MFL reference plate before being used for an inspection.
The calibration procedure has been simplified to minimise operator error

17. Basic Operation – Collecting Data
All operator controls are easily accessible and simple to use.

18. Basic Operation – Collecting Data
All FloormapVS2i Data Acquisition software controls are oversized.
The touch screen can be used even if the operator is wearing gloves.

19. Basic Operation – Collecting Data
All scanning options are shown as graphical images to increase production rates and help minimise operator error.

20. Basic Operation – Collecting Data
Each plate is scanned in a pre-set pattern until the entire plate has been covered.
The width of each scan is 250mm
Maximum single scan length of 15M
Speed of 0.45M per second

21. Basic Operation – Collecting Data
The FloormapVS2i Data Acquisition software captures the MFL signals and displays the location and severity of the corrosion on screen.

22. Basic Operation – Collecting Data
The software displays a colour coded map of the floor plate. Corrosion severity is represented by differences in colour.

23. Basic Operation – Collecting Data
The user can filter the level of corrosion so only relevant defects are displayed on screen.

24. Basic Operation – Collecting Data
More specific corrosion information can be seen by holding the cursor over the corrosion.

25. Basic Operation – Collecting Data
All data from the current inspection is automatically transferred to a USB memory drive with one button click.

26. Reporting Software
Reporting Software

27. Reporting Software
Once the inspection is complete, the Floormap data is imported into the offline reporting software.
There are 2 versions of the reporting software:
FULL version - designed for use by the Floormap operator provides complete control to all data manipulation and evaluation tools.
Read Only version - designed to be issued to end clients locks the inspection data, while providing full access to all of the useful evaluation tools, data comparison tools and patch plate design tools.

28. Reporting Software
Once the data is imported, the reporting software automatically positions each plate to produce a plan of the tank floor.

29. Other tank features and notes can be added.

Issue an electronic report
An electronic copy of the report can be issued to the customer along with the read-only version of the reporting software.
The read only reporting software locks the data to prevent accidental editing, but still allows the user to access the powerful reporting tools.
