Above Ground Markers (AGMs) for Pipeline Pig Tracking

Above ground marker in pipeline
Track pigs in real time with the field-proven APEX system.

Web-Based Pig Tracking System

The Propipe APEX system has changed the way that pig tracking operations are conducted. Through a combination of rugged, field proven above ground marker (AGM) hardware, and innovative PigView software platforms, the APEX system sets the standard for ultra-reliable, accurate, and easy to use pig tracking and data collection.

Our autonomous above ground markers (AGM) enable real-time remote tracking of pigs with EM transmitters, permanent magnets, or acoustically with a geophone input. Get real time passage information, live geophone audio, or historical records at any time.

PPNA is around the world.

Field Proven on 1,000’s of detections

APEX AGMs have been proven on thousands of pig runs and thousands of detections. From our industry leading rental fleet to our ILI partners, our AGM hardware sets the standard.

Compact and Portable Designs

Every single APEX AGM is designed to withstand harsh field conditions, ensuring durability and performance in any environment.

Advanced Sensors

With up to 2 coils, a 3-axis ultra-low-noise geophone delivers precision vibration sensing for accurate pig detection, while 3-axis magnetic sensing provides spatial sensing to enhance detection accuracy and reduce false alarms.

What is an Above Ground Marker (AGM)?

An Above Ground Marker is a surface-deployed pipeline monitoring device used to detect pigs as they travel through a pipeline. AGMs identify signals generated by pigs equipped with EM transmitters or other detectable sources and timestamp each passage for validation and analysis.

Accurate pig passage data is essential for effective pipeline integrity management. Propipe AGMs are designed to integrate directly with pipeline monitoring software, enabling:

  • Time-synchronized pig passage confirmation
  • Reduced false positives in noisy environments
  • Centralized visibility across field and office teams
  • Improved traceability and audit confidence

When paired with PigView Software Suite, AGM data becomes part of a connected pipeline integrity management software workflow, supporting both real-time operations and post-run analysis.
