Diaphragm gas meters BK-G.6 to G5
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.
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.
