User Guide

Online's range of non-intrusive pig signallers accurately detect, signal and log the passage of pipeline pigs at critical points along pipelines onshore, offshore and subsea.

All topside signallers are ATEX certified allowing for installation in hazardous Zone 1 areas such as on platforms and in refineries. All signallers provide a local indication of a pig passage via a graphical display and high brightness LEDS as well as a downloadable event log of up to 100 passages.

Unlike intrusive pig signallers, non-intrusive pig signallers can be installed quickly and easily to the pipeline. They can also be removed without difficulty if maintenance is required, eliminating the need to suspend production and avoiding significant costs as a result.
