1.1 Purpose
The DUOPHON® System is designed for the electro-acoustic water
leak detection as well as for pipe location.
When detecting water leaks the sound pick-up is effected either via
the bodysound microphone (prelocation) or the ground microphone
(localization).
The localization of pipes is carried out with receiver and search coil.
For this purpose the pipe can be energized either directly or
indirectly.
Power carrying cables and cathodically protected pipes can also be
located.
