is wide but the positioning accuracy is lower than other methods. The double
horizontal antennas peak mode has a steeper peak response than the single
horizontal antenna wide-peak mode, the measurement position is relatively
accurate but the signal strength is weaker. When the receiver is above the
positioning pipeline, the signal strength reaches its peak.
First of all, position the target pipeline. Generally, keep the receiver
perpendicularly to ground with the receiver body pointing at the transmitter. If the
signal is directly connected to the target pipeline, walk around the transmitter
with the transmitter as the center and 5-10 meters Radius (if the inductive
connectionis selected, the radius need be greater than 20 meters), adjust the
sensitivity so that the receiver maintains a certain static signal.
Move the receiver gently towards both sides in the presence of a peak response,
find the exact location of the peak response and mark it, which is the location of
the target pipeline.
Illustration of Locating the Pipe with Peak Mode
Use the peak mode to locate the pipeline precisely: When the peak response point is
found, stop and do not move the receiver, turn the receiver in the point, stop until the
response reaches maximum, keep the receiver vertical, move the receiver above the
pipeline, the point with maximum response is the location of the target pipeline.
On the target line, handhold the receiver and keep the receiver body perpendicular to
