non-intrusive ultrasonic sensors for corrosion/erosion monitoring

Metal Samples along with Sensor Networks Inc., offers the smartPIMS® Modbus non-intrusive ultrasonic corrosion/erosion monitoring system which connects directly to a PC or laptop to take isolated measurements, or integrates with your SCADA/DCS system for polling at any user-defined time interval. Data can be readily transmitted to webPIMS™, a cloud based back-end for analysis and trending, or simply exported to XML or CSV as necessary for reporting purposes.

The smartPIMS® Modbus is used for:
• Infrequent data collection (mid-stream applications).
• Hardwiring to a plant’s control system (downstream or offshore).
• Service companies collecting data (refineries).
• Manual data collection (power generation).

monitor corrosion rate
resolution to 0.001” (0.025mm) • high-risk areas • historically problematic locations
monitor “low spots”
post-NDE screening of pits to monitor re-maining thickness • measures down to 0.040” (1.02mm)
replace/augment intrusive methods
validation of coupons, ER probes, etc.
reduce costs
reduce scaffolding and insulation removal/refitting for internal corrosion monitoring • more accurate/reliable data improving operations

  • Connects via Modbus (RS-485) to tablet/PC or SCADA/DCS.
  • Outputs data to XML or CSV file, or directly to webPIMS.
  • Up to 32 units connect on multi-drop network extending as far as 1000’ (305m).
  • Offers 16 single- or 8 dual-element UT probe channels.
  • Transducers available to withstand -22°F (-30°C ) to 932°F (500°C).
  • Maintains 1 mil (0.001” / 0.025mm) resolution and 0.040” (1mm) minimum wall thickness.
  • Sensors install buried or above-ground, temporarily or permanently.
  • ATEX, IECEx, UL/CSA and Japanese hazardous-area certifications.
