The Touchstone 2 for measurement of thick coatings
          Up to 0.316" (8mm) - on steel substrates.

The MFL2000, FloormapVS and HANDSCAN use the Magnetic Flux Leakage technique to detect corrosion in the floors of steel storage tanks.  PIPESCAN uses the same method for testing piping.  From the developer and manufacturer of the worlds best magnetic flux leakage equipment -  Silverwing Ltd. (UK)

MFL2000 is a high speed, motorised magnetic flux leakage corrosion detection scanner capable of inspecting approximately 8000 square feet per shift. The ergonomic design coupled with the latest magnetic technology have resulted in an easy to operate, accurate, reliable and cost effective inspection tool.The motorised scanner takes all the strain giving you more consistent results and less operator dependency.

The MFL2000 corrosion detection floor scanner from Silverwing is a combination of magnetic technology and customer led ergonomic mechanical design. The system is designed specifically with the operator in mind. The availability of a new consistent high quality, magnetic material has allowed a complete re-design of the MFL2000 magnet design. In addition the mechanical design has overcome some of the more difficult and time consuming set-up procedures and also eliminated vulnerable cabling reducing maintenance costs

The latest generation sintered neodymium iron boron magnetic material is used in the MFL2000 inspection system. After extensive mathematical modelling we have designed a magnet that not only gives an increased flux density within the plate but also reduces attractive force. This not only means it is easier for the operator to handle the unit, reducing physical stress and increasing productivity, but reduces wear and tear on the unit itself. The stronger more uniform field achieved across the magnet width, coupled with cut out carriage design allows inspection closer to the edge of the plate than before, allowing detection of corrosion at the edge of the heat affected zone. A further benefit from the mathematical modelling and the revised magnet construction is that we have been able to design the transit case so that the unit can be considered non hazardous (non-magnetic) for air transport

The motorized scanner has an auto-stop system which ensures any defect above the operator adjustable threshold is identified. All controls are situated in a recess at the top of the unit allowing easy viewing and operation whilst being protected against accidental adjustment

FloormapVS2i floor scanner is a Magnetic Flux Leakage method system designed to detect and size underfloor corrosion for above ground storage tanks. The FloormapVS2i is the latest version of the best selling magnetic flux leakage (MFL) floor scanner and now comes with up-graded magnets to improve defect detectability and sizing on thicker materials, faster data capture with a custom designed micro controller and all new software. The VS2i contains significant improvements in terms of defect positioning, electronic data processing and software manipulation.

A new High Specification encoder system has been developed which is electronically calibrated to each individual scanner eliminating errors caused by component tolerances. The new encoder now gives accuracy to within 3 mm on an 8 metre track length and providing it is calibrated on an annual basis will not be effected by normal wear and tear.

The ruggedised on-board computer uses touch screen technology for ease of use within the hostile storage tank environment. The custom designed data acquisition software not only captures all the MFL signals but analyses and displays the location and severity of the corrosion in real time.

The off – line reporting software automatically produces a CAD drawing of the tank floor with the defects being positioned to within 30mm accuracy. All captured data, over 20% loss of the nominal plate thickness, is re-analysed to identify the defect profile and separate the corrosion into 1 of 3 classes. Different sizing algorithms are applied to each class of corrosion ensuring enhanced defect sizing even on badly corroded floors where small diameter deep pits may otherwise have been undersized.

Additional data from visual, ultrasonic, vacuum box and magnetic particle inspection can be added to the report generating a full fingerprint of the tank floor including the annular plates.

Please note that in order to run the Demo software you will need to download Microsoft DirectX 9, .NET Framework Version 2 and NET Version 3.5, unless you have them pre-installed. (pprox 100mb in total)

HandScan MFL corrosion detection mini scanner is designed to compliment the, MFL 2000 and FloormapVS2i floorscanners. Even in such a small configuration the latest generation of permanent magnets enable localized magnetic saturation of the floor area under test.

Signals from corrosion, above the operator controllable threshold, are displayed as both a visual and audible alarm. It’s low profile and extendable handle allow scanning in otherwise inaccessible areas of storage tanks such as the shell to annular area and under pipe work or heater coils.

PipeScan is an easy to use, cost effective, portable, magnetic flux leakage inspection system for the detection of random internal corrosion pipe runs. The latest magnetic material coupled with unique mechanical designs enables coverage of all pipe diameters from 48mm to 2.4 metres with a limited number of scanning heads. Magnetic flux leakage inspection is not affected by product flowing through the pipe so surveys can be carried out both on-line and off-line and at surface temperatures up to 90 degrees C.

CRACK MICROGAUGE Systems (ACFM and ACPD) employ the AC field measurement technique to detect cracks in conductive materials and carbon reinforced plastics.  These instruments can detect cracks even through coatings or under water.   The precision field measurement provides information to determine sizing properties of the detected cracks.  Inspection time is much faster than the magnetic particle method and does not require extensive clean up or re-painting.  Visit our AMIGO page to see the latest field ready system.

  Liquid Level Indicator Model PLI-1

  

  The PLI-1 ultrasonically detects the level of the Liquid to Vapor interface in pressurized cylinders, such as with CO2, Halon, etc.). The instrument operates on the principle that an ultrasound pulse responds differently to the presence or absence of liquid. The PLI-1 generates a sound pulse transmitted by the magnetic based sensor that travels through the steel cylinder wall and into the liquefied gas. It interprets the changes in the echoes that occur as the sound beam responds to the different characteristic impedance of the liquid and the gas or air above the liquid level. The change in response is indicated by the deflection of the meter pointer. The setup procedure for the instrument insures maximum deflection of the meter at the gas/liquid interface, thus making possible a reliable determination of the liquid level.
