The Compensator Safety Monitoring System is an essential tool for monitoring the operating status of gas pipeline compensators (expansion joints). Due to ambient temperature variations, internal pressure fluctuations, pipeline surge‑induced fatigue, and geological instability, cumulative displacement can lead to over‑travelling damage of the compensator.

Leveraging IoT sensing and artificial intelligence, the system uses a vector sensor to monitor compensator status in real time. When axial displacement, rotation, or angular change exceeds preset limits, the system automatically notifies the gas utility for timely action, preventing catastrophic gas accidents.
