AE-Based Monitoring System for Pipe Leak Detection
[ Field Issue ]
Problem
Needs
Manual periodic inspection → high time/cost
Real-time leak detection
No immediate response in hard-to-access areas
Continuous monitoring for instant response
Target pipe is located ~5m high with prior leak history, posing high risk of recurrence.
Periodic inspection and manual response have limits — real-time continuous monitoring is needed
[ Pre-Test ]
Testbed Test
Field Test
Conducted leak simulation tests at 14 field points, verifying that abnormal (LEAK) and normal (NOLEAK) data can be separated even amid real-world equipment/ambient noise
Performed leak simulation in the field to identify signal differences, verifying the sensor can reliably distinguish leak vs. no-leak based on those signals
[ Verification & Application ]
Since March 2023, fixed AE sensors installed on-site for continuous equipment monitoring
During operation, an abnormal signal was captured. On-site inspection confirmed an actual leak had occurred
