Diaphragm gas meters BK-G.6 to G5
Residential or commercial diaphragm gas meters
BK for recording gas consumption values for natural
gas, town gas, propane and butane, as gases of the
first to third families pursuant to DIN EN 437:2003
(DVGW Code of Practice G260). If used for internal
measurements which are not subject to statutory
testing, the gas meter is also suitable for hydrogen,
nitrogen, air and inert gases.
BK with integrated “Smart Valve”
Not suitable for highly contaminated gases, e.g.
town gas.
GB
Potentially explosive atmosphere
Diaphragm gas meters that are labelled with and
(see sticker near the index) are suitable for opera-
tion in potentially explosive atmospheres, see page7
(Declaration of conformity).
This function is only guaranteed when used under the
specified operating conditions– see page6 (Technical
data). Any other use is considered as non-compliant.

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 pressurep
and measuring rangeQ
label/Index plate).
– Note the permitted ambient temperaturetm and
gas temperaturetg, see page2 (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,
ClassE2 for electromagnetic ambient conditions
also applies.
– When installing the diaphragm gas meterBK 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
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 EN60079-14.
– 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.
