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 pressure p
max.
and measuring range Q
max.
, see page 2 (Type
– Note the permitted ambient temperature t
m
and
gas temperature t
g
, see page 2 (Type label/Index
plate) or page 6 (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 pressure
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 applicable
national regulations and the directives of the gas
supply company. For Germany, the valid DVGW
Code of Practice G600 (DVGW-TRGI) applies.
– The gas meter marked with must be included
in the equipotential bond when being installed in
a potentially explosive atmosphere, e.g. by con-
necting it to a grounded pipeline. Installation must
be carried out in accordance with EN 60079-14.
– The gas meter marked with must be protected
from falling parts.
▷
If the calibration seal has been damaged or re-
moved, the gas meter is no longer approved
for measurements which are subject to statu-
tory testing.
▷
If the gas meter is stored or installed outdoors,
protect the site against rain. Condensing humid-
ity is permitted.
Remove protective caps.
▷
Installation in the horizontal position: connectors
must be pointing upwards.
▷
Note direction of flow (arrow).
▷
The gas meter must not be in contact with ma-
sonry or other parts.
▷
Ensure that there is sufficient installation space.
▷
Ensure unobstructed view of the index.
▷
The seal faces on the screw unions must be
clean and damage-free.
