Checking the usage

Diaphragm gas meters BK-G1.6 to G25

Residential or commercial diaphragm gas meters
BK for recording gas consumption values for natural
gas, town gas, propane and butane, 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.
Potentially explosive atmosphere
Diaphragm gas meters that are labelled with
(see sticker next to the index) are suitable for
operation in potentially explosive atmospheres of
Category 2G (Zone 1) of Class II 2G c IIB (TÜV 09
ATEX 554884X), see [Declaration of conformity – p. 5].
This function is only guaranteed when used under the
specified operating conditions – see [Technical data
– p. 4]. 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 pressure p
and measuring range Q
plate – p. 2].
– Note the permitted ambient temperature t
gas temperature t , see [Type label/Index plate –
g
p. 2] or [Technical data – p. 4].
– The gas meter is suitable for mechanical ambient
conditions of Class M1 of Directive 2004/22/EC.
For gas meters with an Absolute ENCODER index,
Class E2 for electromagnetic ambient conditions
also applies.
– 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.
– If the calibration seal has been damaged or re-
moved, the gas meter is no longer approved for
measurements which are subject to statutory
testing.
▷ If the gas meter is stored or installed outdoors, ▷
protect the site against rain. Condensing humidity
is permitted.
1 Remove protective caps.
▷ Installation in the horizontal position: connectors ▷
must be pointing upwards.
▷ Note direction of flow (arrow). ▷
