As a primary inspection tool for corrosion assessments, the Sonatest AlphaGage+ instrument uses dual element transducers in a Pitch & Catch configuration to measure accurately the remaining wall thickness of metal structures subject to corrosion. Dual element transducers have a transmitting element and separate receiving element located side by side, the use of Pitch & Catch reduces any measurement problems which may result from material surface issues.
This product is a key tool to inspect ageing assets and solve problems in many industries but especially, Oil & Gas or Petrochemicals.
Typical applications include:
- metal pipe works
- pressure vessels
- structural parts
- storage tanks

True Thickness (under coating)
When a metal surface is protected by anti-corrosion paint or coating, true wall thickness measurement using Echo-to-Echo function is a key feature and available on all AlphaGage+ models.
Field Upgradable Features
Upgradable in the field, the AlphaGage+ is a flexible solution as it can be fully loaded from the start or upgraded anytime later by easily activating software options when required.
Data Logger (B-Scan)
Thickness readings with ID location for corrosion mapping or profile assessment and send readings to Microsoft Excel™ for further asset maintenance evaluation.
Live Waveform (A-Scan)
Display live A-scan for echo verification and real time control of acoustic range, rectification, gain and blanks or combine the A-Scan with B-Scan view for even more detailed analysis.
Phased Array Technique for Inspection of Contact Point Corrosion
The PA-CAT™ phased array technique developed by Holloway NDT & Engineering Inc. is an attenuation-based modelling algorithm used to evaluate the minimum remaining wall thickness at pipe or vessel supports.
Echo to Echo and Coating Thickness Measurements
Many applications in the Corrosion thickness applications have painted surfaces on vessels, ship hulls, pipes, bridges, and tanks.
Wide thickness range using delay line probes
Aircraft manufacturers have very demanding specifications when it comes to non-destructively measuring the wall thickness of aircraft parts.
Paint on Various Substrates
Most conventional coating thickness gages using eddy current or magnetic induction or other magnetic techniques can easily and accurately measure the thickness of paint on metals such as that on an automotive hood. They cannot measure paint on non-metal materials such as plastic bumpers, composites, wood or concrete.
Build Your Expertise With Confidence
In the past decade, there have been few revolutions in the world of advance ultrasonic technologies; the latest is the introduction of Total Focusing Method (TFM).
TFMi™: Using Intermodal Analysis to Improve TFM Imaging
Total Focussing Method (TFM) is a term given to the mathematical processing of waveforms
collected by a phased array data acquisition process to provide an image of a volume under
Intermodal TFM with Applications to Weld Inspections
Inspection of Nozzles using the Veo3 and Scannner
Traditional UT inspection is time consuming, creating a scan plan and then performing the scan using multiple transducers. When using the Veo3 and Nozzle Scan the set ups can all be done offsite, thereby substantially reducing and easing site work.
Flange Inspection PAUT
Phased array gives the ability to inspect flanges without having to take them apart, resulting in quicker and cheaper inspections.
Phased Array Bolt Inspection
Traditional methods for checking bolts include removing and visually checking for any cracking, this not only takes a long time but can also cost a huge amount of money
