LD6000 combi-detectorLeak detection and acoustic pipe location

Whether you need it for laying outpipes or to narrow down the search orpinpoint a leak –the highly-sophisticat -ed LD6000 and the high-quality micro-phone, which both carry the hallmarksof a product made in Germany, allowyou to determine even the tiniest ofleaks and display the signal before itis processed.

Overview of the functionsF&L mode – hear and see leaksAs many as tenmeasuring cy-cles are dis-played either asa number or a two-segment colour bar– one for frequency and one for volume.The leak is there where the two seg-ments are at their steepest.

Smart modeThe state-of-the-art smart functionis the only one of its kind in itsclass and has been filed for patent– the smarter way to find leaks. Complex algorithmic calculations whichare carried out unseen in the heart of

the device pro-vide you with aclear view ofwhat you need

to see: the exact position of the leak, re-vealed to you by means of a bar indicatorwhich rises sharply where the leak is.It doesn’t get any easier than that!

Long-term measurementsIn order to beable to pinpointthe leak exact -ly, an onboardsound logger can be activated to logmeasurements carried out over a periodof up to 60 minutes, which can thenbe used to determine or rule out anyleaks with the help of the recordedmeasurement.curve.

Pipe detection modeThis mode is designed especially to de-tect plastic pipes which are subjectedto ultrasound via the LD-PULSE impulsegenerator.

Trace gas detectionTrace gas can be used in combinationwith the LD6000 H2 hydrogen sensorto carry out quick and effective leakdetection in pipe networks and pipesystems in houses.

The trace gas used is hydrogen, whichdue to its specific structure is able topenetrate and pass through various ma-terials like soil, concrete, tiles etc. easilybefore then being detected by the sensorat the places where it escapes throughthe system that is being inspected. TheLD6000 is able to show the exact con-centration of hydrogen. The thresholdscan be individually configured and anacoustic and optical signal warns theuser when these thresholds have beenexceeded.

The LD-PULSE is not affected by electriccables and can detect non-metallic wa-ter pipes up to a depth of 2 metreswithout having to close off any part ofthe network or system.

The LD-PULSE generates up to 60 os-cillations per minute which underfavourable conditions can spread outas far as 600 m into the pipe before be-ing detected by a ground microphone,

This means that this method can beused to compile, complete or checkplans and pipe layouts or networks.

LD-PULSE pulse wave generator

The principle of acousticleak detection

Water which escapes from high-pres-sure pipes at high speed causes fric-tion which in turn can be picked upin the form of sound waves.

The pipes themselves start to oscil-late. The sound that is generated istransmitted through the pipes andcan be transformed into audiblesound with a body sound microphoneat a distant contact point (valve, hy-drant, armature)

In addition the water leaking outthrough the crack or hole in the pipegenerates sound which is carriedthrough the ground to the surface.This sound can be picked up by ageophone and transformed into audi-ble sound.

Correlation measurements takeon a whole new dimension withthe mobile PC-based LD20PC all-in-one system. Quality engineering “made in Germany”enables users to identify leaks extremelyflexibly and effectively, thus avoidingexpensive excavations or digging atwrong sites or locations.

The LD20PC is equipped with a steepanalogue filter and a dissipation functionwhich was developed in cooperationwith the Fraunhofer Institute and there-fore able to determine and identifybackground noises and interferencequickly and efficiently before subse-quently effectively suppressing them.

Special optionally available hydrophonesensure accurate results in even the mostdifficult of situations, for example withplastic pipes and long pipe distances.

Advancement through flexibiltyThe countless connection possibilitieswhich the module has to offer providethe user with the greatest possible de-gree of flexibility. As many as four re-ceiver units for three-point correlation

and data logger communication are in-tegrated in the centre of the system.

An optional Bluetooth transmitter allowsyou to conduct wireless measuring ope-rations with the PC correlator overshort distances separate from the sys-tem. Cordless wireless headphonescan be connected to provide you withmore mobility.

A combination comprising high perfor-mance radio transmitters for distancesup to 2,000 metres, an automatic mea-suring mode and a variety of individualsetting options for frequency indepen-dent coherence and correlation analysisand additional wireless data logger ma-

nagement make the LD20PC the idealcorrelator for water suppliers and mea-surement service providers.

Mobile data logger managementThe LD20PC’s onboard receiver for wireless data loggers makes theLD20PC excellently-suited for acousticlong-term zone monitoring.

The logger data can be read out from a moving vehicle and analysed and archived with the LogControl data log-ger software used on the correlator.

In addition, the IR interface can be con - nected via the PC correlator’s USB inter-face to read out the LD5DL pressuredata loggers

All measurement values can be dis-played and documented centrally on theLD20PC when used in combination withthe software for pressure data loggers.

The IR interface can also be connected viathe PC correlator’s USB interface to readout the LD5DL pressure data loggers.

Correlation is a computer-sup -ported process which can beused to locate leaks extremely

accurately.

All leaks emit sound. This sound travelsand is transferred to hydrants, armaturesand valves.

The sound is detected by highly-sensitivesignal receivers at up to three contactmeasuring points and transferred to the

correlator via the LD wireless transmitter.The LD20PC calculates the exact positionof the leak on the basis of the differencesin the time that has elapsed betweenthe signals while taking various factorslike material, pipe diameter and thelength of the distance that was measuredinto account.

In contrast to the electroacoustic me-thod, correlation does not depend onthe volume of the sound generated bythe leak or on other factors like the we-ather conditions or the depth in whichthe pipes have been laid. This meansthat the leaks in the pipe system canbe detected easily when ground sounddetection is not possible.

Why correlation? The benefits of this method…
