Remote Non-Intrusive Corrosion Monitoring

Introducing microPIMS!

A Whole New Approach to Wireless Corrosion/Erosion Monitoring!

A Whole New Approach to Wireless Corrosion/Erosion Monitoring!

microPIMS® is a fully wireless, non-intrusive, ultrasonic corrosion/erosion monitoring system. Powered by battery, it operates using long range (>1 mile/1.6Km) sub Gigi-Hertz wireless connectivity. Each microPIMS sensor is programmed to take readings at a user-defined specified time interval and send data to Sensor Networks proprietary webPIMS® software, a cloud-based back-end web portal for analysis, trending and more.

*Only offering in North America at this time.

Use microPIMS® for:
  • Applications where frequent data is required to monitor corrosion/erosion rate issues.
  • Short- or long-term corrosion rate data is needed to monitor crude-slate changes or to correlate operational system updates.
  • Areas not conducive to manual UT thickness surveys.
  • Covering many discrete points with simple attachment.
  • Situations where quick and easy installations are required.
  • Easy installation (no welding required) and repositioning.

Smarter Remote Non-Intrusive Corrosion Monitoring with Installed Ultrasonic Sensors

Measure It. Manage It.

Take advantage of remarkably cost-effective, modular and robust solutions for remote, non-intrusive monitoring of ID corrosion and erosion using the latest solid-state electronics, wireless or wired technologies, cloud based software and innovative ultrasonic transducer designs.

The versatility and ease of use is amazing!

  • Calculating corrosion rates
  • Monitoring known “low spots” or “areas of interest”
  • Using a non-invasive solution in lieu of or in conjunction with invasive methods (coupons, ER probes, etc.)
  • Reducing recurring access costs
  • Continuously accessing additional & improved data on asset condition

smartPIMS components, software, and systems are highly configurable, from just a few sensors to thousands of TMLs per network. Leveraging the low-cost and ubiquitous aspects of the Internet and wireless networks (including cellular) systems can be easily and cost-effectively installed and maintained at most industrial facilities.

Installed sensors are ideally suited for remotely monitoring areas of active metal loss due to corrosion/erosion.

Wired Solutions

  • Hard wired – (for areas without cellular or wireless infrastructure)
  • No battery on board
  • Collected data manually via tablet/PC
  • ‘Daisy-chain’ up to 32 DSIs on 1000’ RS-485 cable
  • Choose between 16 single element or 8 dual element sensors per DSI
  • Temporary or permanently affix the sensors (except mapPIMS)

Wireless Solutions

  • Ideal for testing a few to a moderate number of points
  • Simple to install
  • Takes readings instantly upon setup at defined intervals (1 per day/week/month/etc.)
  • Cellular IoT connection – Little to no IT support needed
  • Cloud-based back end for analysis and trending & spreadsheet data exporting capability
  • Low cost, highly configurable
  • Battery life: 5-7 years

SNI is pleased to announce that our smartPIMS® product line is now CE Certified including Hazardous-area location certifications for both ATEX Ex II 3 G and IECEx. See attached copies of the certifications. This includes the Cellular, Modbus and Modbus DL installed sensor systems.

Continuous Access to Additional and Improved Data

AWS-hosted cloud-based data management system for ultrasonic thickness measurements from installed UT sensors.

  • Access with most any web browser
  • View, report, analyze the data
  • Remote collaboration with multiuser access
  • Data can be hosted by Sensor Networks or by user
  • Short-term and long-term corrosion rates
  • Set alarms for assets
  • Identify by GPS sensor coordinates
  • A-scan viewing

Why Ultrasound?

  • Safe; Non-invasive to the asset’s pressure boundary
  • Absolute in its ability to directly measure remaining wall thickness (not a proxy for wall loss) at the sensors point of contact
  • Extremely accurate to 0.001” (0.025 mm), with the ability to measure down to 0.040” (1 mm) in carbon steel, especially for fixed-location probes
  • Rugged, reliable and portable
  • Low recurring maintenance costs
  • Versatile and cost-effective
