A new encoder system has been developed, giving positional accuracy FloormapVS2i A new encoder system has been developed, giving positional accuracy to within 3mm on an 8 metre track length.

FloormapVS2i Powerful, easy to use software simplifies data collection, data analysis and reporting.

FloormapVS2i Photographs and results from other inspections can easily be added to the FloormapVS2i report to show total tank floor condition.

The FloormapVS2i is the most operator friendly, comprehensive tank floor inspection system available today.

FloormapVS2i Magnetic Flux Leakage Basic Principles

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 …..

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

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

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

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.

Basic Operation – Collecting Data

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

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

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.

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

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

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

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

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

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

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

Reporting Software Reporting Software

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.

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

Other tank features and notes can be added. Reporting Software Other tank features and notes can be added.

Corrosion can be shown as individual coloured pixels. Reporting Software Corrosion can be shown as individual coloured pixels.

Reporting Software Or each track can be coloured to show the maximum defect found per track.

Reporting Software The exact position and percentage loss of individual defects can be displayed by placing the cursor over the defect.

Digital images can be linked to specific areas of the plate. Reporting Software Digital images can be linked to specific areas of the plate.
