suspected pipe location keeping the RECEIVER vertical and parallel to the direction of the pipe. Signal
will be at maximum when RECEIVER is directly over pipe.
TRACING A PIPE CONDUCTIVELY
(WITHOUT HANDLE)
Direct couple the TRANSMITTER to exposed
surface of the pipe (FIGURE 6). Operate
RECEIVER as described in above paragraph.
NOTE: As distances between TRANSMITTER
and RECEIVER increase, the RECEIVER signal
decreases. Move TRANSMITTER to the last
definite location and proceed with RECEIVER
over the pipe.
CENTERING A PIPE TO DETERMINE EXACT LOCATION CONDUCTIVELY
OR INDUCTIVELY (WITHOUT HANDLE)
Place TRANSMITTER over the pipe or direct coupled to the pipe as illustrated (FIGURES 5 and
6). The operator, at a distance of 25 feet from the TRANSMITTER, then holds the RECEIVER in
a horizontal position parallel to the ground surface. By moving the RECEIVER back and forth
over the general pipeline location, a very pronounced “null” or minimum signal will be noted. The
point of the “null” is the exact center of the pipeline (FIGURE 6).
DETERMINING THE DEPTH OF A PIPE INDUCTIVELY
(WITH OUT HANDLE)
To determine the depth of a pipe accurately, the exact center must first be determined as pre-
described. Once the centering of the pipe has been accomplished, it is relatively easy to
measure the depth by triangulation. The RECEIVER is equipped with a depth level indicator. In
order to determine depths of pipes, it is necessary to position the RECEIVER in a 45
°
angle to the
ground surface. This is accomplished by tilting the RECEIVER until the air bubble in the depth
level gauge lies between the outer edge of the center ring and the black border of the depth level
indicator. Starting at the point directly above the pipe center line, move slowly away from the pipe
at a right angle maintaining the RECEIVER at 45
°
. When new “null” or minimum signal is
obtained, the depth of the pipe below the surface is the same as the distance from the center
