General
This guide is intended for trained specialised per-
sonnel. For this reason no basic working steps are
included.
The tamper-evident seal on the flow sen-
sor must not be broken!
A damaged seal will result in immediate
invalidation of the factory warranty and verifica-
tion. The cables supplied with the meter must nei-
ther be shortened, extended nor changed in any
other way.
Observe the instructions for the use of
flow sensors!
The installation must only be carried out
by a specialist installation or electrical company.
The personnel must be trained in the installation
and handling of electrical equipment and be cog-
nisant of the Low Voltage Directive.
The relevant ESD regulations (electro-
static discharge) must be observed.
No responsibility is accepted for dam-
age (especially to the electronics), resulting from
non-observation of the rules.
This product is designated (where rele-
vant) as a pressure maintaining compo-
nent in the sense of the Pressure Equip-
ment Directive (PED) and may only be operated as
a pressure maintaining component with tempera-
ture sensors suitable for this purpose.
This product is not intended for used as a safety
device in the sense of the Pressure Equipment
Directive (PED).
The following information should be
taken from the type plate of the device in
question:
ƒ
The nominal diameter DN for the pipe
ƒ
The applied test pressure PT in Bar
and the date
ƒ
The intended use
ƒ
The fluid group
Medium
Water according to AGFW-Worksheet
FW510 (the lifecycle of the meter may be
impaired if not observed).
Temperature range
The temperature range is dependent on
the variant and nominal size (see type
plate).
Pipeline insulation
In the case of the pipeline insulation, the
housing with the electronics must remain
free (see Fig. III).
Otherwise the electronic will run too hot and could
be damaged.
Further details about the variants and the appli-
cable standard EN1434 can be found in the data
sheet. These must be observed without fail.

parameterisation and is available online under:

Installation
The unit you have purchased contains
electronic components which could be
destroyed by electric or magnetic fields.
For this reason, neither the device itself nor the
incoming and outgoing cables must be installed
in the immediate vicinity of heavy electrical loads
or their conduits (e.g. switches, electric motors).
The precise separation depends on the magnitude
of the voltage and current in these consumers.
In case of doubt consult an expert.
ƒ
The flow sensor must not be fitted in either a
hot or cold branch of the system. Ensure that
the flow sensor is mounted in the mounting
position corresponding to the temperature of
the medium (see "6. Temperature loads" on
page 9 and Fig. I).
ƒ
The flow sensor must be installed so that the
flow direction matches the arrow direction on
the sensor.
ƒ
Calming sections are not necessary before
and after the flow sensor. For systems with-
out temperature mixing, a straight DN 3 - 10
section upstream of the flow sensor is recom-
mended.
