The Fullagar Corrosion Sensor system is a non-intrusive inspection and monitoring method that wirelessly communicates pipe wall thickness readings to both reduce the need for internal visual inspection and avoid the need for personnel to operate in hazardous locations.
The real-time monitoring system can operate at temperatures up to 300°C and uses energy harvesting as a means of power supply, which allows for permanent installation on expected areas of erosion and corrosion. Higher operating temperatures, of up to 500°C, can be achieved if the electronics are shielded.
The system uses a novel magnetic flux leakage sensor whose magnetic field increases as the thickness of a steel component is reduced. The thickness measurements are transmitted wirelessly and can be read using a mobile app at a 20 metre range, with the sensor system offering cost savings for industry as compared to other monitoring methods.
