  • Device, System and Method for Locating a Pipe
    Publication number: 20140145705
    Abstract: A device, system and method of locating a target pipe in a pipe system utilizes an electric signal transmitter and an electrical signal detector. A pipe locator signal conductor comprises a spool and a flexible insulated electrical conductor wound around the spool. The exposed end of the conductor is fixed near an entry point in the pipe system, and the spool is fed into the pipe system such that the conductor pays off of the spool and extends at least partially through the target pipe. The signal transmitter is coupled to the exposed end of the conductor, transmitting a signal through the conductor and allowing the pipe to be located by the signal detector.
