Valve Leak Monitoring System is real time leak monitoring system by sensor of acoustic emission which in used valve in power plant as well as used main valve in industries site. It is be judged to occurrence of leak that it has acquired to occurred minute signal if leaking of valve, and this signal has done filtering and analysis by algorithm by using on attached sensitivity the AE sensor in inlet/outlet of valve. This system is always monitoring and real-time monitoring of the operation, because the non-destructive evaluation methods, and occurs immediately Alarm. Cause leakage of the valve leakage and assess whether the system will automatically raise alarms to leak the fact that operators will announce. In addition, the leakage occurs at later automatically save the data for the analysis of the precision used for analysis and evaluation of the cause leakage emissions.
