High-Coverage Scanning with Multi-Channel Array Probe

For large or high-risk areas, the PulsePro can be configured with an optional six-channel array probe designed for continuous scanning and C-scan imaging. The array uses a circular probe ring that wraps around insulated pipes and moves along the axis, either manually or electrically to collect dense PEC data in real time. 

This configuration produces high resolution wall thickness maps, identifies potential corrosion zones automatically, and enhances inspection coverage for pipe diameters starting at 140 mm (5.5 in) and larger. It is especially effective for scanning long sections of piping or when rapid, wide-area coverage is essential.

Cladding Penetration Capability & Extreme Temperature Operation

The MFE PulsePro is built to detect corrosion through insulation and protective layers without requiring their removal. 

In standard PEC mode, it can penetrate cladding up to 300 mm (12 in) thick when using stainless steel or aluminum jackets, and up to 150 mm (6 in) with iron coverings. This allows accurate measurement on fully insulated assets, saving time and cost on teardown. 

The system is also rated for in-service operation from –200 °C to +800 °C (–58 °F to 1,472 °F), enabling inspections in high-temperature or cryogenic environments where traditional NDT tools fail. This makes PulsePro ideal for extreme conditions in power, chemical, and petrochemical plants.

MFE PulsePro FAQs

The MFE PulsePro Pulse Eddy Current (PEC) testing system is used across a wide range of industries for inspecting insulated assets, detecting corrosion, and measuring wall thickness without surface removal. Below are some of the most common questions about how the system works, what it can inspect, and how it performs in real-world applications.

The MFE PulsePro is designed for in-service inspection of metal piping, vessels, and structural components to assess wall thickness and detect corrosion.

It enables inspection from the outside of the asset—even through non-conductive, non-magnetic cladding and certain thin metallic protective layers. The system is capable of identifying corrosion and wall loss in both ferromagnetic materials (e.g., carbon steel, low-alloy steel) and non-ferromagnetic materials (e.g., stainless steel, aluminum).

The MFE PulsePro supports inspection across a wide range of materials and asset types:

Materials:

  • Carbon steel
  • Low-alloy steel
  • Stainless steel
  • Aluminum alloys

 

Geometries:

  • Flat plates
  • Straight pipes (≥ 20 mm diameter)
  • Elbows
  • Storage tanks and vessels

 

Cladding / Barriers:

  • Non-conductive / non-magnetic materials (e.g., insulation, foam, asbestos)
  • Metal mesh
  • Thin metallic layers (≤ 1 mm iron or aluminum sheeting)

General Instrument Specifications:

  • Dimensions (W × H × D): 346 × 278 × 136 mm
  • Weight (with batteries): 7 kg
  • Volume: 13 L
  • Power Requirements: AC 100–240V, 50/60Hz ±1%
  • Power Supply: AC/DC hybrid with built-in rechargeable lithium battery
  • Battery Life: Up to 8 hours continuous operation
  • Charging: Integrated rechargeable system
  • Video Output: USB (To output real-time images to the display via the USB port, a USB-to-HDMI adapter is required, and the driver software for the adapter needs to be installed in the host system)
  • Number of Channels: 6-channel system

 

These specifications support both field portability and extended inspection operations.

The MFE PulsePro utilizes pulsed current excitation to generate a transient magnetic field, which induces eddy currents within the conductive test material.

As these eddy currents decay, their behavior is influenced by the material’s thickness and condition:

  • Thicker / intact material: slower signal decay
  • Thinner / corroded material: faster signal decay

 

By analyzing this decay profile, the system determines both relative and absolute wall thickness.

The MFE PulsePro provides high-sensitivity corrosion detection based on a 5% resolution threshold, which refers to:

  • Minimum detectable wall thickness change (Δt) relative to nominal thickness
  • Minimum detectable through-hole diameter within the probe’s inspection area

 

Example (P2 Probe):

  • Inspection target: 10 mm carbon steel pipe under 100 mm insulation
  • Effective inspection diameter: 75 mm
  • Minimum detectable through-hole diameter: 16.8 mm
  • Minimum detectable wall loss: 0.5 mm (for defects ≥ 75 mm diameter)

 

This allows for reliable detection of both localized and generalized corrosion.

Measurement speed defines how many readings are taken per second and is adjustable within the system.

  • Typical range: 15 to 0.5 readings per second
  • As wall thickness increases, measurement speed decreases

 

This is because thicker materials require more time for the eddy current field to stabilize, ensuring accurate readings.

The inspection area (FP/EP) represents the effective circular area being evaluated by the probe.

This parameter directly impacts detection sensitivity—larger inspection areas increase the minimum detectable defect size.

Formula:
EP ≈ 0.4 × L₀ + EP₀

Where:

  • L₀: Lift-off (insulation thickness in mm)
  • EP₀: Probe footprint at zero lift-off

 

Typical EP₀ Values by Probe:

  • P10 = 10 mm
  • P1 = 25 mm
  • P2 = 35 mm
  • P3 = 45 mm

The MFE PulsePro offers five scanning modes:

  • Point Test
    Manual, single-point measurement (no encoder required)
    Best for spot checks
  • Time Scan
    Continuous scanning at fixed intervals
    Ideal for rapid screening
  • Position Scan
    Encoder-based continuous scanning
    Best for detailed mapping
  • Position Step
    Step-based semi-automatic scanning
    Ideal for elbows and complex geometries
  • Position Point
    Encoder tracking with manual trigger
    For precise, controlled measurements

Within the system’s intelligent scanning setup:

  • Through-hole Diameter (mm):
    Automatically calculated minimum detectable defect size based on current probe and settings
  • Axial Step:
    Distance between measurements during scanning
    (e.g., 20 mm step = one reading every 20 mm of probe movement)

 

These values are dynamically tied to the active inspection configuration.

Calibration is performed via the Settings & Calibration interface:

  • Place probe on a known reference area or calibration block
  • Initiate calibration via touchscreen or probe trigger

 

Best Practices:

  • Use a clean, low-corrosion reference area
  • Match material, thickness, and coating conditions
  • Recalibrate when conditions change

The system provides advanced visualization tools:

  • C-Scan View:
    Color-coded thickness mapping
  • B-Scan View:
    Cross-sectional thickness trends

 

Users can analyze:

  • Signal curves
  • Relative and absolute thickness
  • Cladding variation
  • Measurement position

 

Reports can be exported for documentation and client deliverables.

The MFE PulsePro includes advanced compensation features:

Relative Thickness (%):
Expressed as a percentage of nominal wall thickness

  • Cladding (%):
    Represents variation in insulation thickness (not mm)

 

Example:

  • Nominal insulation: 100 mm
  • Actual insulation: 70 mm
  • Displayed value: -30%

 

Key Note:
As long as insulation variation remains within ±40%, measurement accuracy is not impacted.
