Gas leakage detection system for rigid or flexible pipelines for transporting gas, has pressure transducer, microphone, preamplifier, filter, analog digital analog converter and microcomputer

NOVELTY – The gas leakage detection system has a pressure transducer (4), a microphone (3), a preamplifier (5), a filter (6), an analog digital analog converter (7) and a microcomputer (8). The pressure transducer is calibrated to read electrical signal. The microphone is positioned within the gas pipe. USE – Gas leakage detection system for rigid or flexible pipelines for transporting gas (all claimed). ADVANTAGE – The gas leakage detection system has a pressure transducer, a microphone, a preamplifier, a filter, an analog digital analog converter and a microcomputer, where pressure transducer is calibrated to read electrical signal, and thus the gas leakage detection system enables to prevent large-scale accidents by ensuring quick detection of gas leakage. DETAILED DESCRIPTION – INDEPENDENT CLAIMS are included for the following: (1) a method for data acquisition for gas leak detection; and (2) a method for determining the magnitude and location of gas leakage through neural networks. DESCRIPTION OF DRAWING(S) – The drawing shows a schematic view of a gas leakage detection system. Microphone (3) Pressure transducer (4) Preamplifier (5) Filter (6) Analog digital analog converter (7) Microcomputer (8)
