Location Of Pipe Runs

By using the induced magnetic or vibration fields techniques. The magnetic techniques is limited to metal or metal reinforced pipe. The inductive vibration technique is suitable for non-metallic pipe and limited by high background noise and pipe depth or length between valves . In this case, the surrounding condition is enhanced by other sound & vibration measurement & single processing techniques, either by coherent power technique or the vibration intensity technique, Depending on the application.
