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
max
and measuring range Q
max
, see
page 2 (Type label/Index plate).
– Note the permitted ambient temperature t
m
and
gas temperature t
g
, see page 2 (Type label/
Index plate) or page 9 (Technical data).
– The gas meters are certified for mechanical
environments pursuant to Class M1 of Directive
2004/22/EC. When installed, the meters must
not be subject to permanent vibration such as
that caused by machines in the vicinity. In case
of doubt, vibration isolation must be provided.
For gas meter versions BK..A, BK..E and BK..B,
Class E2 for electromagnetic environments also
applies.
– The dangers of chemical reactions between
gas meter parts and the chemical substances
in the environment are to be discussed by the
manufacturer and the operator and must be
eliminated.
– 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 pressure
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.
– Only use the seals once.
– For meters resistant to high temperatures, only
use seals tested to be resistant to high tempera-
tures.
