Online's range of non-intrusive pig signallers are a cost-effective way to signal the passage of pipeline pigs at critical points, onshore, offshore and subsea.

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 risks and costs associated with removing under pressure.

Online’s pig signallers also have advanced capabilities with remote communication options such as LoRaWAN, pig passage data logging and automatic reset eliminating the need for a technician to visit site to reset manually.  Unit parameters can be changed, and data can be interpreted directly from the control room providing additional operating flexibility.
