4.2
Specifying a device number (optional)
Every Logger is assigned an 11 digit serial number by the manu-
facturer before shipping. In order to simplify the job of managing
the loggers (in the
Master
software and at the measurement
location) it is possible to assign each unit a device number. Any
number may be selected
, up to a
maximum of four digits
. This
number could, for example, be the same as the last four digits
of the serial number.
1. It is advisable to decide on a format that can be used as the
device number for all loggers.
2. Each logger should be labelled with the device number.
3. The device numbers must be saved with the corresponding
serial number in the
Master

Installing the logger at the measurement location
4.3.1
Suitable installation locations
The logger can be mounted on:
●
Pipes
●
Fittings (slide gates, underground hydrants, above-ground
hydrants)
Note:
Only attach the logger to above-ground hydrants if it is possible
to protect the device against theft and vandalism.
The units can be installed both in water pipe networks construct-
ed from metal and
plastic piping
. Please note that if installed in
plastic water pipe networks:
●
The logger cannot be mounted directly on the pipe, instead it
has to be attached to a fitting.
●
On plastic piping sound is not transmitted as well as in metal
pipework systems.
