Above Ground Marker (AGM)

Propipe APEX 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, rare earth magnets or acoustically with a geophone input.

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 Above Ground Marker (AGM) relies on digital signal processing methods to provide robust and false-alarm free passage information. Raw data is streamed to the cloud via cellular connection or satellite radio.
