The LD6000 cutting-edge
leak detection device sets
new standards in the field
of leak detection…
Whether you need it for laying out
pipes or to narrow down the search or
pinpoint a leak –the highly-sophisticated LD6000 and the high-quality microphone, which both carry the hallmarks
of a product made in Germany, allow
you to determine even the tiniest of
leaks and display the signal before it
is processed.
Overview of the functions
Pipe detection mode
As many as ten
measuring cycles are displayed either as
a number or a two-segment colour bar
– one for frequency and one for volume.
The leak is there where the two segments are at their steepest.

be used to determine or rule out any
leaks with the help of the recorded
measurement.curve.

Long-term measurements
The state-of-the-art smart function
is the only one of its kind in its
class and has been filed for patent
– the smarter way to find leaks.
Complex algorithmic calculations which
are carried out unseen in the heart of
the device provide you with a
clear view of
what you need
to see: the exact position of the leak, revealed to you by means of a bar indicator
which rises sharply where the leak is.
It doesn’t get any easier than that!
Trace gas detection
Trace gas can be used in combination
with the LD6000 H2 hydrogen sensor
to carry out quick and effective leak
detection in pipe networks and pipe
systems in houses.
The trace gas used is hydrogen, which
due to its specific structure is able to
penetrate and pass through various materials like soil, concrete, tiles etc. easily
before then being detected by the sensor
at the places where it escapes through
the system that is being inspected. The
LD6000 is able to show the exact concentration of hydrogen. The thresholds
can be individually configured and an
acoustic and optical signal warns the
user when these thresholds have been
exceeded.

3. The pipes themselves start to oscillate. The sound that is generated is
transmitted through the pipes and
can be transformed into audible
sound with a body sound microphone
at a distant contact point (valve, hydrant, armature)
r
y
i
In addition the water leaking out
through the crack or hole in the pipe
generates sound which is carried
through the ground to the surface.
This sound can be picked up by a
geophone and transformed into audible sound.

Sound and pressure data logger
Mobile zone monitoring of drinking water systems
Leaks in drinking water systems do not only endanger
the quality of your water supply – precious water seeps
out uncontrollably resulting in losses worth hundreds
or thousands of pounds...
The mobile wireless monitoring
system in the Trotec MultiMeasure
Professional Series enables you to
carry out reliable acoustic zone
measurements in drinking water
systems in order to detect possible
cracks, fissures and leaks.
A magnetic base and optionally available
mounts and brackets allow you to position your wireless data logger in a variety of different positions to measure
the sound levels in the pipe system or
network.
BENEFITS IN PRACTICE:
LD5DL pressure data logger :
Designed specifically for monitoring
pressure in water supplies.
Robust, waterproof– no prod contacts

Extremely large memory for more
than 240,000 measuring values
Very high measuring sensitivity
Infrared / USB data transfer
and infrared / GSM (optional)
Battery life for approx.
10,000,000 measuring values
In addition, a model with a hydrophone
can be used for measuring operations
that are carried out with the medium
water – ideal for plastic pipes or pipe
networks that cover greater distances.
The wireless data loggers detect, analyse
and log sound levels during the night
when less water flows through the systems and transmits all the measuring
data up to 12 times a minute.
All measuring data can be picked up
and logged from a passing vehicle with
the use of a mobile LD5LR receiver.
The leak status and further measuring
data are displayed directly on the
LD5LR’s easy-to-read display.

All logging data from the LD5LR receiver
can be transferred to a PC via the USB
interface for further analysis and documentation.
The LogControl data bank

Quality engineering “made in Germany”
enables users to identify leaks extremely
flexibly and effectively, thus avoiding
expensive excavations or digging at
wrong sites or locations.
An optional third receiver and a radio
transmitter with a separate radio frequency can be added to the two onboard
receivers which are already standard for
the TR-TA and TR-TB radio transmitters.
The three-point correlation enables you
to achieve even faster measuring results
over greater measuring distances.
The LD20PC is equipped with a steep
analogue filter and a dissipation function
which was developed in cooperation
with the Fraunhofer Institute and therefore able to determine and identify
background noises and interference
quickly and efficiently before subsequently effectively suppressing them.
Mobile data logger management
Special optionally available hydrophones
ensure accurate results in even the most
difficult of situations, for example with
plastic pipes and long pipe distances.
The LD20PC’s onboard receiver for
wireless data loggers makes the
LD20PC excellently-suited for acoustic
long-term zone monitoring.
TRT-KAT-CORR-WM-02-EN
The logger data can be read out from
a moving vehicle and analysed and
archived with the LogControl data logger software used on the correlator.
In addition, the IR interface can be connected via the PC correlator’s USB interface to read out the LD5DL pressure
data loggers
All measurement values can be displayed and documented centrally on the
LD20PC when used in combination with
the software for pressure data loggers.
The IR interface can also be connected via
the PC correlator’s USB interface to read

the volume of the sound generated by
the leak or on other factors like the weather conditions or the depth in which
the pipes have been laid. This means
that the leaks in the pipe system can
