reinforced concrete pavement because the signal will be shielded by metal covers or steel bars.
The inductive connection method cannot be used to apply signals to well-insulated pipelines
unless both ends of the pipeline are connected to ground well.
Illustration of inductive connection
1)
Distance between Transmitter and Receiver
The transmitter will send signals to its upper space and the lower part of the pipeline at the
same time, so the receiverwill receive the signal from transmitter if it is close to the
transmitter. In order to distinguish whether there is any effect on the receiver from the
transmitter source, move the transmitter to one side by one or two meters, and if the
anomaly detected from the receiver is also moving, it means that the distance between the
receiver and the transmitter is too short and the received signal comes from the transmitter.
Another method is to point the receiver directly to the transmitter, then if there is no change
of the abnormal phenomenon or if the abnormality is increasing, then the receiver receives
the signal from transmitter. If this happens, you should increase the distance between
receiver and transmitter or reduce transmitter output power and reduce receiver sensitivity.

Placing the transmitter
Place the transmitter on the "positive" side of the target line,and in the same pipeline
