m.
Possible reasons:
Pipeline is suddenly deepened. You can increase the sensitivity to continue the
detecting.
There may be a "T" -shaped branch, and the pipeline may also change direction.
Check whether more than one tube carries the signal in the circle. If the pipeline is more
than one, measure the response of each pipeline from the distance away from the
intersection of 4-5 meters. The strongest response comes from the main line and the
weak one is from the "T" -shaped line. This is because the signal always selects long or
large pipeline for the better earth circuit, which is very useful for detecting the main line
and the branch line
The signal completely disappears probably because it has reached the end of the
pipeline or the metal pipeline has been changed into a plastic pipeline or the pipeline is
crossing a metal plate or cover. Please continue to detect.
When the signal is gradually reduced, and sometimes nothing can be detected by
even improving the sensitivity. Then you can add the output power of the transmitter to
the maximum, the pipeline can continue to be detected.

If the signal becomes blurred and the signal distribution is very wide, pipes may be
under the steel mesh net, which absorbs and sends out radiation signals. At this time
raise the locator by 0.5m and minimize the sensitivity. You will be able to receive the
signal and continue to detect without being affected by the concrete.In a variety of
circumstances see Figures a to e as below.
