Leak location equipment for waste water channels - includes remotely controlled mobile unit with pressure chamber, over pressure generator and pressure sensors

摘要

An arrangement for locating leaks in waste water channels contains a remotely controlled mobile device (1) which can generate an overpressure and has two chamber walls (2) which seal a pressure chamber (7) formed by the walls and the section of channel between them. Pressure sensors measure the overpressure in the chamber and in the double walls. A measurement and computer unit compares the individual pressure variations with time and displays the leakage rates. USE - Location of leakage points in general but esp. of those below water level.
