10Basic 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 …..
11Basic Principles of MFL The FloormapVS2i uses powerfulpermanent rare earth magnets, which achieve localmagnetic saturationof the tank floorplatesPermanent Magnets
12Basic Principles of MFL An array of 36 Halleffect sensorsare mountedbetween the2 magnetpolesSensor Array
13Basic Principles of MFL The magnetic leakage field is detected by the hall-effect sensors and converted to an electrical signalThe powerful magnet induces a uniform magnetic field close to saturation in the plateWhen corrosion is encountered the magnetic field is forced outside the plate
14Basic 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.
16Basic 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
17Basic Operation – Collecting Data All operator controls are easily accessible and simple to use.
18Basic Operation – Collecting Data All FloormapVS2i Data Acquisition software controls are oversized.The touch screen can be used even if the operator is wearing gloves.
19Basic Operation – Collecting Data All scanning options are shown as graphical images to increase production rates and help minimise operator error.
20Basic 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 250mmMaximum single scan length of 15MSpeed of 0.45M per second
21Basic Operation – Collecting Data The FloormapVS2i Data Acquisition software captures the MFL signals and displays the location and severity of the corrosion on screen.
22Basic Operation – Collecting Data The software displays a colour coded map of the floor plate. Corrosion severity is represented by differences in colour.
23Basic Operation – Collecting Data The user can filter the level of corrosion so only relevant defects are displayed on screen.
24Basic Operation – Collecting Data More specific corrosion information can be seen by holding the cursor over the corrosion.
25Basic Operation – Collecting Data All data from the current inspection is automatically transferred to a USB memory drive with one button click.
27Reporting SoftwareOnce 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.
28Reporting SoftwareOnce the data is imported, the reporting software automatically positions each plate to produce a plan of the tank floor.
29Other tank features and notes can be added. Reporting SoftwareOther tank features and notes can be added.
30Corrosion can be shown as individual coloured pixels. Reporting SoftwareCorrosion can be shown as individual coloured pixels.
31Reporting SoftwareOr each track can be coloured to show the maximum defect found per track.
32Reporting SoftwareThe exact position and percentage loss of individual defects can be displayed by placing the cursor over the defect.
33Digital images can be linked to specific areas of the plate. Reporting SoftwareDigital images can be linked to specific areas of the plate.
34The software features a powerful patch repair design tool. Reporting SoftwareThe software features a powerful patch repair design tool.
35Reporting Software Defects from any other inspections can be added to the tank floor report.
36Weld inspections can also be added with additional comments. Reporting SoftwareWeld inspections can also be added with additional comments.

42Issue an electronic report Reporting SoftwareIssue an electronic reportAn 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.
43FloormapVS2i - Specification Thickness range: Maximum 12.5mm (automated sizing mode)Maximum 20mm (detection mode only)Max sensitivity: 20% under floor corrosionMaximum coating thickness:6mmScan width: 250mmMaximum single scan length:15 metresSpeed: 0.5m/ secPower requirements: 12v battery operation - Supplied with 3 batteries and 2 chargers to allow continuous working
44Acceptable Floor Conditions Surface Preparation RequirementsAcceptable Floor ConditionsFloor plate cleaned to bare metal using high pressure washingGenerally acceptable – some spurious results possible from blistersFloor cleaned to acceptable standard – some thin scale remainingFloor acceptable – top surface pitting now visible
45Surface Preparation Requirements Not Acceptable Floor ConditionsProduct residue and hardened scale presentThick layer of scale present60mm thick layer of product residueHardened scale and loose corrosion products
46FloormapVS2iWe are convinced that the powerful reporting software coupled with the advanced FloormapVS2i scanner makes this the best tank bottom inspection system on the market today.
