(2) 45 Degree Depth Measurement
First of all, measure theaccurate location and direction of the target pipeline and switch the
receiver mode of operation to valley mode, put the bottom of the receiver on the ground above
the pipeline, adjust the receiver body to the ground at a 45-degree angle and move the receiver
along the direction perpendicular to the pipeline. When the received signal is the minimum value,
mark the point on the ground. The distance between the marked point and the measuring point is
same as the buried depth of the pipeline.
The above several depth measurement methods are often used to verify the accuracy of depth
measurement during the detection process, of which 80% is the most commonly used and it is
relatively accurate especially in complicated pipe network. The 45 degree measurement needs to
master the receiver body Angle with the ground. Direct reading depth method used in complex
environments often comes with big deviation. It is more suitable for long-distance single buried
pipeline depth measurement.
(3) Current Measurement
Compared with the traditional pipeline, this underground pipeline detector can also measure the current
on the target pipeline, which can help operators better identify the target pipeline. In pipeline intensive areas,
the receiver may detect a stronger signal on the interfering pipeline than on the target pipeline because it is
shallower than the target pipeline. In this case, it is difficult to accurately distinguish the target pipeline from the
interference pipeline if only the signal strength is measured. The current measurement function can effectively
