2 AQUAPHON system
2.1 Acoustic water leak detection
Water leak detection includes preliminary detection and pinpoint-
ing. A microphone must be connected to the AF 50 receiver to
be located acoustically with the AQUAPHON system. The mi-
crophone picks up noises and plays them back through a set
of headphones. This means that leak noise can be detected in
pipelines.
2.2 Pipe location
Analternatingcurrentmustowthroughalinetobelocated.
The SK 3searchcoildisplaystheeldstrengthfromtheAF 50
receiver and transmits it as an audible signal to the connected
headphones.
A distinction is made between the following location techniques:
●Passive
●Active
2.2.1 Passive pipeline location
Forlinesthatarenotonlyenergizedbutalsounderload,the
alternating current required for location is already available. The
appropriate receiving frequency can be set at the AF 50 receiver:
●50 Hz
●60 Hz
2.2.2 Active pipeline location
The alternating current is produced using a generator (e.g. gen-
erator FG 50). The following frequencies can be set at the AF
50 receiver:
●512 Hz
●1.1 kHz
●9.95 kHz
