The multifunctional F.A.S.T.-LOKAL 300 leakage detection system is applied to detect leakages (correlation and geophone) on drinking-water networks and to trace out pipelines. Simple operational handling enables even unskilled operators succesfully to locate leakages.
The pressurized medium inside the pipe generates a leakage-borne noise at the leakage spot. This noise travels in both directions through the pipe and is detected by highly sensitive sensors which are mounted at accessible places such as hydrants, valves etc..
The amplified pick-up signal is radio-transmitted to the central unit, and the coherence and correlation functions are calculated and displayed by the LCD.
Overview of benefits
- portable
- Correlator / Geophon / Listening device in one compact system
- user-friendly operation manual
- sturdy aluminum case
- real 500 mW radio power
- direct loading via car cigarette lighter
- Headphone jack on central unit and measuring boxes
Testrod and Geophone:
The testrod has been developed by F.A.S.T GmbH and features an extremely high sensitive. It has been designed to detect even minute leakages. As the length of the testrod is adjustable, it is perfectly well suited to listen to water meters and to systematically check pipeline network sections.
When leakage-borne noises have been detected with the testrod or when the result of the correlations has to be double-checked, the integrated geophone can be applied. The filters are automatically or manually set according to the kind of leackage-borne noise. The in-built data memory device allows a comparison of the detected noises and thus supports the pinpointing process to precisely locate the leakage.

Lokal 200 PC
With our LOKAL 200 PC we introduce the most modern and strongest Correlator available. Thanks to his precipitous analogous filters and the dissipations function developed by the renowned German Fraunhofer Institute it is possible to recognize disturb noises and to suppress straight.
The especially for transport and plastic pieplines, developed Hydrophone-sensors, allow excellent results on this part of the network too. The GPS supported Software has features for 3 point correlation, automatic calculation of the filter settings and leak recognition.
Overview of benefits
- real 500 mW radio power
- FFT-Function
- Coherence function
- 3 point correlation
- GPS- supported data collection and archiving

FTT-Correlator - Lokal 100
Operation of the LOKAL Leakage Detection System by F.A.S.T is based on the technical principle of the frequency-dependent correlation coherence analysis. The pressurized medium inside the pipe generates a discharge-related noise at the leakage spot. This discharge noise propagates to both ends of the pipe section simultaneously and is acquired through sensitive pick-up units at accessible spots such as valves, hydrants, etc.. The amplified signal is then radio-transmitted to the coherence correlator and converted into cross power spectrumcompatible data by means of FFT algorithms. Further data processing provides coherence / correlation, which will be displayed on the LOKAL screen.
Overview of benefits
- high spotting accuracy for pipes made of steal, cast iron, asbestos and PVC
- automatic leak detection and spotting routine
- integrated automatic rejection of disturbing noises
- user-friendly operation manual
- frequency analysis (coherence spectrum)
- easy data evaluation of pipe sections consisting of mixed materials and featuring different diameters
- no misdiggings at reflection spots such as T-junctions, the end of a pipe, or angles etc.
- data reprocessing without any additional measurement procedure possible
- VGA color display

Gas-Check
Gas-Check
The H2 Measurement Procedure:
With the Gas-Check-H2 even tiny little leakages can be pinpointed. Hydrogen diffuses through almost any material due to its molecular size. The pipeline section to be checked is filled entirely with gas, and the pressure is increased slowly until the measurement varies according to the size of the leakage, the kind of soil, and the surface structure. The leakage on the pipeline will be below the the spot showing the highest concentration of gas. Usually, the location indicated by the gasCheck does not deviate by more than a few centimetres from the actual leakage location.

Aqua M300
Aqua M 300 D
Acoustic Leak Detection with Geophon:
A clear and concise displaying supports the leak statement effectively. 256 free and automatic adjustable filter settings achieve effective reduction of noise pollution and best results. Thru the automatic adjustment of amplification and filters the displaying of smallest leaks is certain.
Tracer Gas Detection:
Even the most advanced filter cannot suppress any interference noise, because this some leak is only partially audible. For this instance the Aqua M-300D is fitted with the ultimate Tracer Gas Technology to locate the leak. This decades-proven, safe and accepted method by the international Water Wise Associations (DVGW, IWA, AWWA etc...) is now available for the first time in this smart combination.
Tracing plastic Pipes with PWG:
The localization of plastic pipes is still a major challenge. The Aqua M-300D in combination with the PWG offers an excellent complement to conventional systems, like ground radar and fiberglass detection probes.
Pyramid Mode:
The pyramid mode determined by means of intelligent algorithms in the background automatically optimizes the leak information and thereby enables an unmatched precision in the positioning of the leak. By using these innovative and unique methods of measurement and ultimate Chebyshev analog filter withd 48 dB / octave slope, noise pollution effectively is eliminated. The integrated data logger function provides the ultimate review of the leak. This is particularly useful in situations with high ambient noise. By recording the sound, till a maximum of one hour and closing the pipeline to check, the leak noise can be safely distinguished from pollution noises.
