The SPY Pig Tracker is a reliable and
simplified way of locating and/or tracking
pigs that are used in pipelines today. The
SPY Pig Tracker is available in 4 models:
  • PT 101 Transmitter
  • PT 107 Transmitter
  • PT 275 Transmitter
  • PT 750 Transmitter

The above picture shows an RCC with a cavity containing a transmitter.  In this specific instance the 8” pipeline reduced to just over 3” due to heavy build-up on the pipe wall.  By using the pig tracking system the users were able to locate this section of pipe for removal and repair without excavating the entire line.

Pig Tracking System

Pig Tracking is a method of verifying either the pigs location or movement through the line.  Tracking the movement reduces the search area in the event a pig does become lost or stuck in the line.  This is very beneficial in lines that are not pigged routinely and especially in lines that have never pigged before.

The pig tracking system consists of a Transmitter and a Pig Tracking Receiver (PTR).  The transmitter is inserted and secured into the pig prior to its launch.  Polly, Turbo and Mandrel pigs can all be made to hold the appropriate size transmitter.  The transmitter uses low frequency signals to penetrate the pipe walls.  When these signals are picked-up by the PTR it emits both an audio and visual notification.

The standard method of using the pig tracking system is setting up stations and moving down the pipeline in a “leap frog” manner, which leave smaller sections of the line to search in the event the pig does not reach the 2nd station.
