Abstract：Objective To monitor gas leakage of gas pipeline or gas cylinder in hospital, this study
developed a gas leakage monitoring system. Methods The digital signal processing technology was
adopted to analyze and process the ultrasonic signal produced by leakage and the acoustic pressure level
calculation, thus the leakage detection and leakage amount estimation were realized. Results The gas
leakage was realtime
monitored effectively and the medical risk was prevented. Conclusion This system
has stable performance, strong portability and wide market prospects.
