The Truflux is a new concept in Magnetic Flux Leakage tank floor plate inspection, incorporating a new level of user sophistication in its innovative design. It is a fully self-propelled high-resolution digital scanner, and capable of producing highly accurate topographical images of 0.24in-0.8in (6-20mm) storage tank floor plates.

calibration tab

It is vital that the TruFlux is calibrated on a known test plate before an inspection of a tank floor is carried out.

If using the software for the first time a calibration file must be produced for the material thickness you intend to inspect. Multiple calibration files for each material thickness can be produced at any one time.

Calibration files are stored for a maximum of 30 days, where after a new calibration will be required. The software will always use the most recent calibration file.



Allow motor to move the instrument from the start point to end point, on the plate, in one continuous smooth operation. It is important for the instrument to run the entire length of the calibration plate, including the first 300-400mm before the first indication. As this part of the plate is calibration panel
used to capture data where there are no indications, this is an important part of the calibration as general noise levels are eliminated. Once stopped, unlatch or re-press the calibrate button.

Once satisfied with the signal display, you can move each cursor bar onto its corresponding indication. You will notice that each moveable bar has a number that corresponds to each indication. Pick up the bars individually and place into the center of each indication – bisecting the indication through its center.



The bars are used to register the signal amplitude that corresponds to each percentage loss indication. This then sets the reference amplitude curve for the software when scanning.calibration screen

Once this has been done the calibration can be accepted by pressing the accept button.

Now the calibration has been completed, inspection's relating to that particular plate thickness, can begin.

All calibration types are stored for a maximum of 30 day, there after a new calibration will be required.


inspection tab


Before commencing any inspection program the operator should ensure the following information is available.


1. All floor plate thicknesses including annular plate
2. If any floor plate coatings are present and their thickness; simulation of coating thickness will have to be simulated during calibration
3. General condition of plates – floor plates need to be free from loose scale and relatively clean
4. Presence of heater coils and other obstructions
5. Floor plate numbering system to be used


Step 1 – Inspect
From the front panel click inspect

Step 2 – Inspect Panel – ‘Project' Tab
The inspect panel comprises of three parts: project, tank and plate. Navigation between the panels can be done by either – clicking on the tab control, or when project, tank and plate data has been added, by using the drop-down lists.

Step 3 – Inspect Panel – ‘Tank' Tab
Once the project has been created, you can create tanks within the project. Type the tank name or description into the box and press enter.


Step 4 – ‘Plate' Tab
To create plates, enter a plate number into the plate field. You can enter as many plates as needed, dimensions will be identical to the first plate, however you can change their dimensions any time prior to collecting data


Step 5 – Scanning Mode
Press the scan button. The instrument should now be in position to start scanning runs, with the first track starting from the selected datum point.


Step 6 – View the Results
You will now see a scanned plate image. To view in greater detail; right click on image and select full screen.



After following these steps, you will be able to create a report. It produces a full printable PDF file output, of all plate images within the project selected.

auto drawing tab

The software produces a full-scale drawing of the tank floor, with auto numbering of plates and tracks, including annular rings. Scanned plots of tracks are auto positioned onto plates, as are the plates into the tank image. All file and directory handling are produced automatically, resulting in faster track-to-track scanning speed. auto drawing image
