Graffin Pig tracking systems are designed as accurate Pig tracking & location for onshore and offshore subsea pipelines, operating in liquid or gas lines. The system provides an effective solution for tracking the movement of pigs in real-time, and locating them if they get stuck or lost. The device equipped with a receiver that intercepts the signal emitted by a transmitter installed on the cleaning pig.

Pig tracking systems are available in two forms: electronic and acoustic. The acoustic pig tracking system is used for moving pigs and uses sound amplification to track the passage of the pig. In other hand, the electronic pig tracking system involves using a pig transmitter, which is a low-frequency magnetic type device that can be installed on the pigs. This system also includes a receiver system with an antenna and recorder that is used above the ground to detect the location of the pigs.
