5.2 Pipe location with the DUPOHON®
Another purpose of the DUOPHON® System is the location of
underground pipelines.
5.2.1 Energizing of a pipe
The requested operating mode is adjusted with rotary switch
(Item 1):
Direct energizing - pulse tone position 1.1
Direct energizing - constant tone position 1.2
Indirect energizing - pulse tone position 1.3
Indirect energizing - constant tone position 1.4
When the pipeline shall be energized directly (Refer to pict.3) a
connection must be made between the transmitter/earth plug and
between the transmitter and a pipe fitting (Item 6). The earth plug
should be pushed into the soil within a few meters’ distance and
rectangular to the pipeline.
Pict. 3
Direct energizing of a
pipeline
For an indirect energizing (Refer to pict.4) the transmitter must be
placed onto the trace such way that both arrows (stickers) are on
top of the device pointing to both directions of the pipeline.
Pict. 4
Indirect energizing of a
pipeline
After switching-on the transmitter (Item 3) the „10 kHz“ signal can
be received above the pipe’s trace.
