6. Additional features  

6.1 Task:  

Indirect electromagnetic mode of depth 

measuring 

Equipment used:  

receiver AP-027, electromagnetic 

sensor EMD

Tip: When determining the depth, one should take into 

account  the  terrain.  In  order  to  obtain  precise  results, 
select flat surface areas.

Method: 

1. Find the precise pipeline route location 

(preferably using the minimum method). Mark the spot.
2.    Fix  the  sensor  antenna  at  a  45  angle  to  the  ground 

surface, minimum of the signal is observed at a distance 
from the point «above the route», equal to the depth of the 
utilities, when the antenna axis intersects the axis of the 
route. This is the indirect method of measuring the depth 
of utility (

fig. 6.1

)

6.2  Task:  Detecting the pipeline and utility lines 

intersection point. 

Equipment used: 

receiver AP-027, electromagnetic 

sensor EMD, headphones. 

Fig.6.1

Fig.6.2

Method: 

1. Perform preliminary pipeline route 

location.

2. Turn on the receiver and set it up for broadband.
3. Рosition the electromagnetic antenna over the 

pipeline, parallel to the pipeline route (signal level 
displayed on the receiver screen will be close to zero)
(

fig. 6.2

). Perform route location in accordance with 

the maximum method. When following the route, the 
intersection points with utility lines can be identified by 
the maximum signal.
