  • Method and device for detecting leaks in an underground liquid pipe, particularly a water pipe
    Patent number: 8931330
    Abstract: The invention relates to a method for detecting leaks in an underground liquid pipe (T), particularly a water pipe, into which a gas is fed through a diffuser (8) into the liquid of the pipe, the atmospheric content of the gas being low; and the path of the pipe is traced along the pipe surface with a detection system for measuring at consecutive points the content of the air in the injected gas, an abnormally high content constituting a leak indicator. A diffuser (8) is selected having outlet pores for the gas, the mean diameter of which is less than 50 ?m so as to produce gas bubbles, the diameter of which is small.
