Interface parameters, see page 9 (Technical data).
▷ As regards explosion protection, pulse transmit-
ters IN-Z6x are classified as simple electrical
apparatus and must thus not be marked.
Other communication modules
Meters which are marked with

Technical data
Diaphragm gas meter BK
Gas type: 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).
The following technical data can be found on the
type label/index plate:
– max. allowable operating pressure p
– measuring range: Q
– max. allowable ambient temperature range t
– max. allowable gas temperature range t
– cyclic volume V
For meters with temperature conversion only:
– base gas temperature t
– specified centre temperature t
Other technical data:
– transitional flow rate Q
– max. allowable storage temperature range:
-25 to +60°C
– mechanical environment class: M1
▷ Observe installation conditions! See 4 (In-
stallation).
– electromagnetic environment class: E2
Supplementary notes:
* If operated within the gas temperature range, the
measurement error still lies within the required
error limits. If no gas temperature t

** The specified centre temperature t
G...E... series and BK-G...B meters is not stated
