Tightness test
▷ Check the pipework for leaks prior to installa-
tion of the gas meter, in case the pipework is
tested with a greater test pressure than the max.
allowable operating pressurepmax for the gas
meter. Otherwise, the installed gas meter may
be damaged.
▷If a valve is integrated in the diaphragm gas me-
terBK, see page3 (Diaphragm gas meters
with integrated valve), this must be opened for
the tightness test.
▷Ensure the customer’s consumers are closed.
 Apply the test pressure slowly to the gas meter.

Diaphragm gas meters BK with integrated
valve
In the event that the diaphragm gas meterBK is fitted
with an integrated valve, see page3 (Diaphragm
gas meters with integrated valve), the gas supply can
be connected or disconnected remotely.
Unless otherwise agreed, the valve is open on delivery
as standard.
WARNING
– The grid operator is responsible for the safe
remote shut-down and restart of the diaphragm
gas meter.
– The integrated valve does not assume the func-
tions of a safety shut-off valve.

▷
Should the diaphragm gas meterBK be ordered
with a valveVp, but without control electronics to
be complemented by a third party, the technical
data of the control interface is to be requested
from ElsterGmbH and observed.
▷
The manufacturer of the control electronics is
responsible for creating the conditions required
for safe operation of the valve. Instructions on
commissioning and operation are to be taken
from the operating instructions for the control
electronics.

... with valve variant Vs (Smart Valve)
WARNING
– Depending on national regulations, a limited
and technically safe gas flow rate in the cus-
tomer’s open consumer piping is allowed, see
page7 (Technical data).
– Assessment of the non-critical gas flow rate with
regard to amount and duration, which occurs
when the valve is released, is to be carried out
by the grid operator.
– The minimum operating pressure on the inlet
must not be undershot, see page7 (Techni-
cal data). Otherwise, when the valve is released
and if the customer’s consumer piping is open
at the same time, the valve may be completely
opened.
“Smart Valve” valve function
▷ The “Smart Valve” is switched remotely by the data
management system. The valve first switches to
the “Released” position. From the “Released” posi-
tion, the valve automatically switches to the “Open”
position, if the downstream installation is tight.
Released
▷ The “Smart Valve” opens an internal bypass and
releases a minimum gas flow into the customer’s
closed consumer piping. Pressure equalization
takes place between the inlet and outlet side
of the valve.
Open
▷Following pressure equalization, the valve auto-
matically opens by spring force and fully releases
the gas supply. If consumers of the customer are
open, pressure equalization cannot occur and
the valve remains in the “Released” position and
continues to release only the minimum gas flow
rate of the bypass.
Closed
▷ The valve and the bypass are closed in the event
of remote shut-down.
▷All valve positions are kept de-energized.
Maintenance/Removal
Gas meters BK-G1.6 to 25 from Elster are mainte-
nance-free (constraints for BK-G...E... and BK-G...B).
▷When used for custody transfer measurements,
recalibration must be carried out in accordance
with national directives.
▷
If the screw unions are loosened for maintenance
work or retesting, replace the seals.
▷After the gas meter has been removed, immedi-
ately close the connectors with protective caps
in order to prevent ingress of dirt particles.
▷ For meters with electronic indexes(BK-G...E...
and BK-G...B), it may be necessary to change
the battery, see “Operating instructions for op-
erators and installers” for the corresponding
electronic index.
WARNING
A certain amount of gas may remain in the gas
meter. Taking into consideration the risk of explo-
sion, it is important to adopt safety measures, e.g.:
– Following removal of the gas meter, purge it
thoroughly with inert gas.
– For transporting the gas meter with gas residue,
use a vehicle with an open or a ventilated load-
ing area.
– The indexes must not be opened in an explo-
sion-hazard area even for maintenance and
repair. Opening of the service cover on the
electronic index, e.g. to change the battery,
is permitted– see “Operating instructions for
operators and installers” for the corresponding
electronic index.
– Meters which are installed in a potentially ex-
plosive atmosphere may only be cleaned using
a damp cloth to avoid static electricity charge.
Accessories
We recommend using Elster GmbH accessories only.
Meters which are marked with may only be ret-
rofitted with communications modules certified in
accordance with 94/9/EC and which correspond
to the appropriate interface parameters (see page
7 (Technical data)).
