Pipeline pig location system Asel Tech

SONIC PIG LOCATOR
As is the case with the SLDS system, the signals leave from a point (in the SLDS case, the leak) and move in both directions towards the adjacent acoustic sensors.

In the case of the SPL – SONIC PIG LOCATOR – the sonic signal’s “starting point” is the PIG itself, as it moves in the pipeline. The operator can follow the PIG’S movement in the pipeline with great precision. If the PIG gets stuck in any pipeline dent, curve, valve or in any other restriction, the acoustic emitter installed in it will issue signals in a frequency warning the PIG is immobilized at that point, allowing for immediate rescue actions.
