Installation
WARNING
Please observe the following to ensure that neither
persons nor the gas meter are damaged during
installation and operation:
– Note the max. allowable operating pres-
sure p
max
and measuring range Q
max
, see
page 2 (Type label/Index plate).
– Note the permitted ambient temperature t
m
and
gas temperature t
g
, see page 2 (Type label/
Index plate) or page 7 (Technical data).
– The gas meter is suitable for mechanical ambient
conditions of Class M1 of Directive 2004/22/EC.
For gas meter versions BK..A, BK..E and BK..B,
Class E2 for electromagnetic ambient conditions
also applies.
– When installing the diaphragm gas meter BK
with integrated valve, make sure that no dirt
particles get into the meter and thus into the
valve.
– The yellow sealing sleeve protects the pres-
sure test point on the gas meter. It may only be
opened for connecting a pressure measuring
line.
– Use seals made from tested materials. Elastomer
seals or asbestos-free flat seals from Elster are
recommended.
– For meters resistant to high temperatures, only
use seals tested to be resistant to high tempera-
tures.
– Only use the seals once.
– For installation and operation, note the applica-
ble national regulations and the directives of the
gas supply company. For Germany, the valid
DVGW Code of Practice G600 (DVGW-TRGI)
applies.
– Work on meters and the installation of meters
which are marked with
and are installed in
potentially explosive atmospheres may only be
carried out by persons with appropriate qualifi-
cations.
