Installing the GSM Logger at the measurement
7.1
Suitable attachment points
The
GSM Logger
can be mounted on:
Pipes
Fittings (slide gates, underground hydrants)
The units can be install in water pipe networks constructed from
both metal and
plastic piping
. Please note the following points
relating to plastic water pipe networks:
The
GSM Logger
cannot be mounted directly on the pipe, but
must instead be attached to a fitting
Sound is not transmitted as well as in metal pipework sys-
tems.
The
GSM Logger
can be installed either vertically or horizon-
tally. The aerial must however always be be positioned vertically,
pointing either upwards or downwards (see also Sections 7.3
and 7.4.1).
7.2
Distance between two Loggers
The distance between two Loggers and the choice of attachment
point is always
dependent on local conditions
(special features
of the network, pressure fluctuations, etc.).
Water pipe material
Recommended distance between
Loggers [m]
Metal
300 – 500
Plastic
50 –300
For highly intermeshed water pipe networks, the distance between
Loggers must be decreased appropriately.
