How many times
have you found that utilities marked on network plans are
not always where they should be when you get out into the
field? Very often in order to find the leak in a pipe the
first thing you need to be able to do is to find the pipe
itself, so we designed a version of the AQUAPHON® which
is also a pipe locator and tracer.
This instrument is called the AF100. |
|
|
By plugging in the receiver A3-S the AF100 becomes a highly
sophisticated pipe & cable locator and tracer. It offers all of
the functions you will find on the standalone locator and tracer
the ELH. |
The Aquaphon AF100 is far more than simply a cable avoidance
tool.
The AQUAPHON® AF100 shows you: |
It is very useful to know if you are tracing the correct
service and knowing the depth of what you are tracing can
give you more information. A water pipe is unlikely to be
buried, (but it has been known!), at 300mm but a telecommunication
cable might well be!
- Minimum & Maximum detection methods
The Minimum method is particularly useful for tracing pipes,
very accurately, instead of increasing at the centre of
the pipe the signal decreases giving a far cleaner “centre”.
|
|
|
|
- Six reception frequencies including:
- Radio - This range picks up re-radiated VLF radio
signals that are in the air
- 50/60Hz - mains electricity frequency
- Line location arrows - These point in the direction
that the signal is strongest allowing you to see if
the pipe to the left or right?
|
|
|
|
|
Re-scaleable signal level allowing you to infinitely vary the
displayed signal to enable you to narrow down the area of search
and hone in on the service. |
| |
|
The technique that the AF100
is utilising to locate metallic services is to detect the
electromagnetic field that surrounds the service or the
re-radiated radio signal.
To be detectable by the A3-S the line undertest must either
be carrying current, to produce an electromagnetic field,
or be re-radiating radio signals to
utilise the Radio setting. For a power line to produce an
electromagnetic field it must be pulling power, so if there
is no load you may not detect the service. It is far safer,
and more advisable, to produce a known signal and trace
the consequent electromagnetic field. For this purpose we
provide
2 signal generators. |

|
The signal generator
(genny) G1
Provides 3 output frequencies with a powerful 50W transmitter
(it has controllable output for times when you do not need
this large power output).
The G1 is powered by an internal rechargeable battery and
can run or be recharged from any 12V power by the cigar
lighter accessory lead. Calculate how much you currently
spend on batteries for your less powerful signal generator
and consider the advantages this offers. |
|
| The signal generator G2 is
a 2W signal generator with three output frequencies |
|
|
|
|
A full range of accessories is available including fibreglass
probes and mini pig transmitters for end line location. |
Features & TECHNICAL DATA
- Wide choice of microphones to suit many different types
of work
- Automatic microphone recognition - Best frequency settings
automatically selected
- Digital signal processor - for digital sound clarity

distinguish sounds easier to hear. Simple to use even for
the most inexperienced user
- Minimum Noise Level - displays the lowest level of noise
whilst you have been listening- Leaks do not get quieter but
background noise can. More useful than knowing what the loudest
noise was
