iPIG is a ground breaking pipeline inspection technology that can be adopted by oil pipeline transport companies. The iPIG works on the principle of saturating the carbon steel oil pipe section with high magnetic flux and monitoring the leakage flux on inner surface of the pipeline with the help of 64 Hall sensors over its full periphery. The iPIG consists of a magnetic module, DAS module, a battery module, residual sensor with DASII module and a PIG Locator module. IPIG consists of a Magnetic Module, a Data Acquisition System (DAS) Module, a Battery Module, Residual Sensors with DASII Module and a PIG Locator Module. Three odometers are also attached to record the movement of IPIG.
