CDRiA Pipeline Services Ltd offers its own portable pig tracking and location system, dedicated to the detection of the pig passage and to the location of the pig stuck inside the pipeline.
 
In general, pig tracking and location system consist of:

• The transmitter (1) mounted at the front of a pig, emitting a low frequency electromagnetic signal,  
• The receiver placed near the pipeline, above or under the ground, which records both an electromagnetic signal (2) and sound vibrations (3) resulting from a pig movement in a pipeline.

 
The pig tracking and location system is offered in a few configurations, depending on the receiver type -  (see  The pig tracking and location system leaflet for detailed information)
 
The available receivers differ with functionality and field of application:

	ROIC-09  - Receiver operated by an inspection crew  (communicates with an external PC computer)
	ARMF-09  - Autonomous receiver (maintenance-free)
	RSTT-09   - Receiver equipped only with a sound vibrations detector (geophone)

Pig location:

RLPL-09   - Receiver for stuck pig location  (equipped only with an electromagnetic signal detecto

Main features of CDRiA receivers:

• both geophone and electromagnetic signals are recorded,
• integrated nonvolatile memory allows recording of several pig tracking locations (above 20)
• recorded data are correlated with GPS system coordinates  (for receivers equipped with GPS unit),  
• continuous work time: up to 2 weeks,
• communication with external host computer (via radio or USB interface),
• multi-device synchronization for all receivers.
