Ekoscan METIS Phased Array Thickness Measurement and Corrosion Mapping Scanner

Ekoscan METIS is a field-deployable encoded manual phased array scanner for wall thickness measurement and corrosion mapping on pipes, elbows and valves. A flexible phased array probe, dual-axis encoding, real-time analysis and digital recording come in one package, turning manual spot UT readings and handwritten results into traceable, repeatable, high-resolution thickness maps.

The problem it solves

In many plants, piping wall thickness is still measured manually at pre-marked points with single-element probes, and values are written on paper. The weaknesses are well known:

• Results are operator dependent; the same point may not be measured the same way in two campaigns.
• Handwriting causes transcription errors, and data is neither audit-ready nor traceable.
• Local thinning between grid points can be missed.
• Complex geometries such as elbows, tees and reducers are hard to measure with standard probes.
• Long measurement times, heavy couplant use and poor ergonomics increase safety risk.

What it does for your operation

• More data in less time: denser inspection per campaign, shorter setup and acquisition time.
• Fewer specialist operators: a guided workflow lets operators of all levels use the system.
• Reliable data for long-term operation (LTO): encoded, recorded measurements compare campaign to campaign, making thinning rate and remaining life assessment easier.
• Audit-ready records: measurements are stored digitally, with recording compliant with nuclear operator EDF’s requirements.
• Fewer consumables: less couplant and hazardous consumables.
• Protects past investment: the modular architecture works with legacy systems and digital asset management systems.

System components

• Flexible phased array probe: conforms to pipe curvature and complex geometries and covers a wide strip in one pass.
• Dual-axis encoded acquisition: every reading is stored with its position; the result is a C-scan thickness map.
• Real-time analysis and digital recording: the thickness map builds on screen during the scan and data is validated in the field.
• Guided workflow: a step-by-step interface from setup to reporting.
• Compact, field-deployable design: quick setup and work in tight spaces.

Applications

• Primary and secondary piping in nuclear power plants
• Steam generators and valves
• Flow-accelerated corrosion and erosion (FAC) monitoring programmes
• Wall thickness mapping on elbows, tees, reducers and other complex geometries
• Fast, traceable thickness campaigns during outages
