APEX Above Ground Marker

APEX logoAPEX AGM enables remote pig tracking, live geophone audio, simple downloads and historical records management over the internet.

Propipe APEX above ground marker is an ultra-reliable, accurate and easy to use intelligent above ground marker (AGM) that enables live remote tracking of pigs with Trident EM transmitters, magnets, or acoustically with a geophone input. The APEX allows live data to be streamed to any online device, either locally or worldwide. Users who pair these devices with our unique intelligent EM transmitters, can build an entire system that tracks, logs, collects and processes pipeline data from in-situ pigs easily, seamlessly and live.

The APEX above ground marker relies on digital signal processing methods to provide robust and false-alarm free passages. Geophone data is streamed to the cloud using the embedded cellular connection or satellite radio. Pigs can be tracked live and remotely through our web-based portal PigView-Web.
