Diaphragm gas meters BK-G.6 to G5

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

operation in potentially explosive atmospheres, see
page7 (Declaration of conformity).

The meter function is only guaranteed when used

under the specified operating conditions– see
page 7 (Technical data). Any other use is con-
sidered 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 pres-

surep
page2 (Type label/Index plate).

– Note the permitted ambient temperaturetm and

gas temperaturetg, 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.
