RMS is a Non-Destructive Testing (NDT) remote-access automated Ultrasonic (UT) scanner. With multiple configuration options, the RMS is capable of high-speed Phased Array (PAUT) corrosion mapping, high-temperature corrosion mapping and weld inspection utilizing both PAUT and ToFD probes.
Details
Phased Array Corrosion Mapping (RMS PA)
Automated corrosion mapping has become an integral part of NDT inspection campaigns and is widely accepted within integrity management programs and written schemes of examination. However, to optimize productivity, corrosion mapping systems have traditionally been set with a relatively coarse resolution: data points every 3 to 5 mm (0.12 to 0.20 in).
With phased array UT technology, the RMS PA automated corrosion mapping system can help increase productivity, without sacrificing probability of detection, thanks to a 1 mm (0.040 in) resolution. Mapping a 1000 mm x 600 mm area as quick as 1min 30 seconds.
Phased array probes have a wide electronic footprint, and with a 1 mm (0.04 in) resolution across the width of the beam, the required scanning coverage is achieved with significant time reduction. The ability to collect high-resolution data at increased scanning speeds improves the probability of detection, enhance imaging, and improve defect characterization.
The water box produces a controlled and stable water-column which eliminates the need for a wedge, thus providing the benefits of improved signal consistency, accuracy, and limited dead zone. This concept offers enhanced surface conformance and improved coupling.

R-scan Array Manual Scanner
The RMS PA integrates a detachable handheld manual scanner for the inspection of smaller areas and assets ranging from 101 mm (4 in) to flat plate.
The R-scan array can be purchased as an independent scanner, simply connect the scanner to an M2M instrument and you have a semi-automated phased array corrosion mapping system with onboard data collection capabilities.
Ideal for complex geometry components and restricted access areas the R-scan array offers improved inspection dexterity and total battery-operated portability.
Weld Inspection (RMS-WELD)
Phased Array UT (PAUT) and Time of Flight Diffraction (TOFD) has quickly become a go-to technology for both fabrication welding and in-service inspection.
RMS bolt-on bracket adds automated weld inspection capabilities.
- Up to 4 probes (PAUT and TOFD)
- Suitable for pipework from 6 in diameter up to flat plate
- Steerable with laser guidance
Automated Corrosion Mapping (RMS SCUT/Dual element)
Single crystal (SCUT) immersion testing technique option is available via a UT ready control box, when paired with the RMS laptop this option does not require to be paired with a PAUT instrument. The SCUT method is also available as an integrated option when paired with Eddyfi Technologies PAUT instruments (Enquire about use with other Instrumentation). The transducer is held in a gimballed probe holder, ensuring it remains perpendicular to the surface and allowing it to ride over weld caps & lap joints up to 8 mm high. The stainless steel wear plate prevents transducer damage when scanning over rough surfaces.
- Wide range of applications up to 200˚C (392˚F)*
- Inspect materials as thick as 150 mm (5.9 in)
- High probability of corrosion detection with up to 0.5 mm (0.02 in) scan grid
- Optional dual element
* Umbilical cable requires high temperature sleeving
RMS Scanning Heads
The robust, field-proven RMS robotic scanning head has been successfully deployed on various assets such as storage tanks, pressure vessels, pipelines and other critical structures in harsh environments including oil and gas, offshore, mining and assets at temperatures up to 200°C (392°F). The steerable tractor units incorporate high torque stepper motors and powerful magnetic drive wheels ensuring the scanner remains fixed to the inspection surface even whilst inverted.
RMS-600 ideal for scanning rates on large surface areas such as tank shells, pressure vessels, and other structures.
RMS-450 is designed for operating circumferentially on curved surfaces such as pipelines or pressure vessels from 152 mm (6 in) up to flat plate.
RMS-300 a general-purpose scanner for inspecting areas with limited access, vessel heads or other applications where smaller scan widths are required.

Instruments
The cutting-edge Gekko and Mantis phased array systems have a growing reputation for being the most advanced phased array instruments on the market. Eddyfi is the first brand to deliver portable phased array flaw detectors capable of driving matrix arrays and performing TFM in real time.
Gekko phased array ultrasound flaw detector is IP66, allowing operators to bring it into the field without having to worry about rainy and dusty environments. Gekko supports extreme weather conditions.
Mantis is a light and economical version of Gekko using the same technologies and software interface Capture™. With a 16:64 pulsers receivers architecture, Mantis combines standard PAUT, conventional UT, TOFD, and real-time Total Focusing Method (TFM).
Both Mantis and Gekko instruments have the RMS Motor control embedded within the Capture platform.
Integrated RMS Control Software
Fast and easy inspection setup with the RMS scanning heads being preconfigured within phased array software.
The user interface is developed to ease the workflow. The RMS control software is embedded into the M2M instruments and functions seamlessly with the phased array data capture and analysis software.

This unique technology combination allows inspection versatility when performing non-intrusive inspections of pressure vessels and associated pipework. To complete a thorough NII inspection, there are requirements to perform a variety of advanced Ultrasonic Testing (UT) methods. In addition to corrosion mapping of the shell, the industry recommended practice is to perform Time of Flight Diffraction (ToFD) on welds, and manual phased-array for flange face and nozzle welds. With the RMS PA phased-array system, operators are now able to perform the full NII inspection by a simple change of probes.
