Method and apparatus for locating underground water pipes
The invention is of an acoustical pipe location system and method of use, by which hidden water pipes may be located. The system and method involve the introduction of low frequency acoustic vibrations into known portions of pipes, or pipe network components which are known to be connected with...
A method of locating underground pipe damage involves detecting the noise output from the pipe using a microtone connected to the input of an amplifier which drives an indicator showing the noise maximum level. The associated equipment is improved compared to conventional types such that the ...
