holes for installation of removable rods (magnet
pos.2, rods pos.3 and pos.4) and extension
handle pos.5. The set of sensor includes
plastic plug-screws (for protection of threaded
holes from dust and water) and a key (pos.8).
3.1. Set content of acoustic sensor
threaded
hole plug
While working with acoustic sensor without removable elements for handling, use the handle
on sensor cable to position the sensor (pos.9) .
Using of magnet allows to attach the acoustic sensor to metal pipes and isolation valves. While
preparing the sensor for the operation with removable handle and (or) rods, these plugs should
be removed. After finishing the location the accessories should be removed and the plugs should
be placed back.
3. Acoustic sensor AD-227
3.2. Structural and operation features of acoustic sensor
Sensitive element of acoustic sensor is placed on steel sensing base (later on – base). The
base is hanging at snap diaphragm made of sound-proof rubber and protected from external
noise with safety cuff. Overall design of the sensor reduces the distortion of external noise and
prevents mechanical damage of body.
Best protection from external noise is provided when cuff is placed fully on ground surface.
(also when using rods).
When working with sensor, the cuff is placed fully against the surface, and the base of sensor
should touch the ground surface.

While working with sensor, please, make sure you are not pressing it too hard. The sensitive
base may strike of vertical movement mechanical stopper. It may cause the unwanted noise in
headphones and distorted signal. The distortion of signal may happen when sensitive base is
placed incorrectly due to roughness of ground surface. When placing the sensor, choose as flat
surface as possible.
When working on soft soil or in high grass or snow, use removable rods.
The rods are installed and removed manually. If necessary Allen keys (supplied) can be used to
install and remove the rods. (one key is put into the hole of the rod, the second – into the hole in
the base of sensor to prevent cranking of the base and damaging of the sensor)
WARNING! Using one key to install the rod is prohibited!
When using the rods, please, make sure that protective cuff fully touches the surface of the
ground. This helps to exclude the influence of unwanted noise. (Pic. 3.1).
If it is impossible to place the cuff so it fully touched the ground, provide as much silence as
possible. (Pic.3.2).
Pic. 3.1 Pic. 3.2
Indicated useful signal level fully depends on the position of the sensor. Comparison of signal
levels can be done only when the sensor is placed in multiple points at similar conditions..
Moreover, the signal level in each point should be measured several times and average value
should be considered as true.
Some elements of sensor are made of rubber, that is why it is restricted to clean the sensor with
sharp tools. It is also restricted to bash the sensor over hard surfaces in order to clean it off the
dirt. In order to clean the sensor rinse some water on it.

5.3 Route location methods
1.The Maximum method
This method consists of positioning the electromagnetic sensor in the direction of the
magnetic field created by the utility radiation (fig.4.3). EMD antenna must be positioned
horizontally and the sensor placed in a plane perpendicular to the cable route. In this case the
maximum signal level is observed when the sensor antenna passes directly above the utility
line. The maximum method is intended
for a quick route location. Flat peaks of
the signal level curve do not allow for
high location accuracy, but enables a
quick route location.
2. The Minimum method
When the EMD antenna in a vertical (transport) position is placed directly above the route
the signal is at its lowest level fig. 4.4. As the distance from the point directly above the pipeline
increases, the signal level first rises sharply then slowly decreases. This is the minimum method,
which is used to determine a more precise
route location (after quick route tracing
using maximum method.

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.
