If a pressure measuring line has been retrofitted
to the diaphragm gas meter, protect the pressure
test point against external access with a sealing
sleeve and a seal.
Commissioning
Once the tightness test has been successfully com-
pleted, the gas meter is ready for operation.

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 network provider 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.
... with valve variant Vp
▷
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 customer’s
open consumer piping is allowed, see page 6
(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 defined by
the network provider.
– The minimum operating pressure on the inlet
must not be undershot, see page 6 (Technical
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” position, the valve automatically
switches to the “Open” position, if the down-
stream installation is tight.
