Checking the usage
White meters BK V to BK V
White meters are components of diaphragm gas
meters and cannot be operated independently. They
are suitable for recording gas consumption values
for natural gas, town gas, propane and butane,
as gases of the first to third families pursuant to
DINEN437:2003 (DVGWCode of PracticeG260),
and can be extended to form complete diaphragm
gas meters by installing an index.
The following sizes of gas meter can be assembled
from the listed white meters:
Meter Size
BK V G4
BK VS G4, G6
BK V6 G6, G10, G16
BK V G25
Potentially explosive atmosphere
White meters that are marked with and (see
sticker on the base plate) are suitable for operation
in potentially explosive atmospheres, see page7
(Declaration of conformity).
▷
If a pressure/temperature sensor is integrated
in the white meter, this must be included in the
ATEX assessment of the control electronics.

WARNING
Please observe the following to ensure that neither
persons nor the meter are damaged during installation and operation:
– Note the max. allowable operating pres-
Integrated pressure and
temperature sensor (optional)
As an option, a combined pressure/temperature
sensor of type KP089 made by elgass.r.o. (Czech
Republic) can be integrated in the meter.
In this case, the conductors of the connection cable
are assigned as follows:

– Note the permitted ambient temperaturetm and
gas temperaturetg, see page6 (Technical
data).
– The white meters are certified for mechanical ambi-
ent conditions pursuant to Class M1 of Directive
2014/32/EU. When installed, the meters must

Integrated valve (optional)
A valve of type Ve may be integrated in the meter as
an option. This is marked on the type label below the
year of construction with the note “Valve Ve”.
WARNING
Risk of explosion in explosion-hazard areas!
– The intrinsic safety of the control electronics
must be proven.
– When working on electrical equipment in an
explosion-hazard area, only design-approved
electrical operating equipment may be used.
– Check that the electrical system complies with
the special electrical explosion protection requirements.
– Note the permitted connection ratings of the
interfaces. See page 6 (Technical data),
White meters BK V with explosion protection
and integrated valveVe.
▷ A connection cable leads out of the meter.
▷
There is a detailed specification for actuating the
valve and using the interface. Please contact the
manufacturer.
▷
The manufacturer of the control electronics is
responsible for creating the conditions required
commissioning and operation are to be taken
for safe operation of the valve. Instructions on
that caused by machines in the vicinity. In case
of doubt, vibration isolation must be provided.
– When installing meters with integrated valves,
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 meter. It may only be opened
for connecting a pressure measuring line.
– Use seals made from tested materials. Elasto-
mer seals or asbestos-free flat seals from Elster
are recommended.
– Only use the seals once.
– For meters resistant to high temperatures, only use
seals tested to be resistant to high temperatures.
– 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 qualifications.
– The meter marked with must be included in
the equipotential bond when being installed in a
potentially explosive atmosphere, e.g. by connect-
ing it to a grounded pipeline. Installation must be
carried out in accordance with EN60079-14.
– The meter marked with must be protected
from falling parts.
– Avoid subjecting the unit to mechanical stress
and prevent damage. Gas meters must be in-
stalled without any mechanical stress, preferably
only by suspending them on the connectors.
When using additional clamps, it must be en-
sured that no lateral forces act on the gas meter.
These can be avoided by using flexible or supple
connection lines, for instance.
