2. Introduction
Welcome to the AQUASCOPE 2 leak detection system. The
AQUASCOPE 2 is a digital acoustic leak locator with superior crystal
clear sound with simple to use operation. It’s light weight with a waist
strap for user comfort. The AQUSCOPE 2 has a versatile hand probe
for direct sounding and leak location on soft ground.
3. System Components
AQUASCOPE 2 system is supplied with the following configuration:
All Configuration Types include:
Amplifier control unit with waist belt
Stereo Headphones
Connection Cable
Hand probe microphone
2 x Probe rods including 1 with a tip
4. How to Switch on the Amplifier
Turn the volume control knob clockwise to turn the amplifier on. When
the headphones and microphone are connected a comfortable volume
level can be set.
Note: In order to save
battery consumption,
please ensure that the
volume control knob is
always set to ‘0’ (off
position) when the
device is not in use.
5. Connecting the Headphones
The headphone is connected to the AQUASCOPE 2 control unit via the
3.5mm stereo socket.

6. The Hand probe Microphone
Screw the desired amount of probe rods together as required, generally an
extension together with the tip rod is recommended. Next, attach the rod
assembly to the hand probe microphone. The longer the rod assembly the
more background noise is introduced especially on windy days. Some
people lag the rod with pipe insulation to reduce wind noise. The hand
probe is used for direct sounding on pipes and fittings.
6.1Techniques using the hand probe Microphone with Rods
The following photos show example methods of using the
AQUASCOPE 2 hand probe:
Caution: when probing through the soil it’s highly recommended
that a certified insulated probe such as a punch bar is used. This helps
prevent the possibility of electrical shock or damaging the aluminium
rods while probing through the ground.

6.2How to find leaks with the AQUASCOPE 2 listening stick
An electronic listening stick is usually used to perform a leakage survey
by walking the street listening on every valve, hydrant and accessible
service connection. Each sounding is usually for 10 to 15 seconds. It
takes longer to assess the noise when there is more background
noise. It is not unusual to perform this work at night in busy cities when
the pressure is highest and the background noise is lowest. It is
important to hold the stick still and firmly pressed against the pipe,
valve or hydrant. Ensure there is no long grass or cables making
contact with the stick.
The electronic listening stick is considered to be a localization tool used
to localize the leak position; however when the leak is suspected to be
in a pipe under soft ground, the electronic listening stick can be used to
pinpoint the leak. It is preferable to make the hole with an electrically
insulated punch bar or another probe and then insert the stick into the
hole made. Extreme care should be taken to ensure there is no
contact with other underground services. Check with your company
Health and Safety Officer before proceeding with this method.
1. Listen on all fittings in an area making note of the noise frequency and
characteristics. It is usual to listen at each location for a period of 10
seconds, waiting for background noise to stop. If there is noise
generated from consumption, pumps, road works or heavy traffic you
will need to return when the noise stops.
2. Use a pipe locator to trace and mark the pipe location in the area of
interest and check to see if there are any other services in the same
trench as your pipe.
3. If it is safe to do so, make a series of holes at 3 meter intervals in the
ground with an insulated punch bar and insert the probe from the
electronic listening stick into the ground as deep as it is safe.
4. Continue this process along the section of pipe work until the leak is
found. Holes will need to be made at 1 meter intervals when the leak
has been located to a 6 meter span.
5. Determine which point has the loudest minimum noise.
6. Perform a “star check” moving about 30 cm from this point to all 8
points of a star. Each point should have a lower noise than the pin-
pointed leak position. If a point has a louder noise than the centre, this
could be the correct position, repeat the star check to verify.

6.3Techniques using the hand probe Microphone with Tripod
The optional hand-probe tripod attachment is used to find leaks buried
in concrete slab, walls and shallow ground. Attach to the tripod foot, lift
or move the hand-probe to each point and then listen.
The following photos show example methods of using the
AQUASCOPE 2 hand probe with Tripod:
6.4How to find Leaks with the AQUASCOPE 2 Tripod foot
The tripod foot is a pinpointing tool that attaches to the electronic
listening stick in place of the probe bars. It is used to find leaks in
concrete slab, shallow underground pipes and in walls. It should
always be placed or held in a still position during operation.
1. Localise the leak position with noise loggers or an electronic listening
stick. If a Correlator is available this can be used to narrow down the
location to a much smaller area.
2. It is best practice to locate the pipe position with a pipe locator.
3. Follow the path of the pipe listening for the leak at 1 meter intervals.
4. When the location with the highest noise has been identified use your
leakage experience to confirm this is a leak noise.
5. Perform a “star check” moving about 30 cm from this point to all 8
points of a star. Each point should have a lower noise than the pin-
pointed leak position. If a point is louder this could be the correct
position, repeat the star check to verify.
