Having proven success with its ground based analyzers, Airwave has modified the AE2420 FID Hydrocarbon Analyzer to operate in a moving instrument platform for Aerial Pipeline Leak Surveillance of gas and liquid pipelines. Along with the hydrocarbon analyzer, a GPS(Global Positioning System) and Data Acquisition System complete the platform, which is mounted in a fixed wing aircraft and flown 100 to 200 feet above the ground, at a speed of 100 MPH. The hydrocarbon anomalies are recorded and leaks are confirmed by means of a surface investigation. This patented system has been used to survey over 40,000 miles of pipeline in Canada and the United States to date.
