What are Non-Intrusive Pig Signallers?
Non-Intrusive Pig Signallers are devices used to monitor and track pigs inside pipelines without making any direct modifications or taps to the pipeline itself. Unlike intrusive signallers, these devices work externally, using sensors or magnetic/electronic detection to sense the pig as it passes through the pipeline.
They are ideal for sensitive pipelines where welding, tapping, or direct contact is not possible or desired. Non-intrusive pig signallers provide safe, reliable, and real-time pig tracking for various pigging operations.
