Diaphragm gas meters BK-G.6 to G5

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.

The meters are designed for use in air at normal

atmospheric conditions. For use in other environments, please contact the manufacturer (see also page 4 (Installation)).

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10 (Declarations of conformity).

The meter function is only guaranteed when used

under the speciﬁed operating conditions – see page 9 (Technical data). Any other use is considered as non-compliant.

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 page2 (Type label/Index plate).

– Note the permitted ambient temperaturetm and

gas temperaturetg, 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.

RUS

SRB

– For installation and operation, note the applicable

1 2

national regulations and the directives of the gas supply company. For Germany, the valid DVGW Code of Practice G600 (DVGW-TRGI) applies.

– Work on meters and the installation of meters

which are marked with and are installed in potentially explosive atmospheres may only be carried out by persons with appropriate qualiﬁcations.

– The gas meter marked with must be in-

cluded in the equipotential bond when being

installed in a potentially explosive atmosphere,

e.g. by connecting it to a grounded pipeline. Installation must be carried out in accordance with EN60079-14.

– The gas meter marked with must be pro-

tected from falling parts.

– Avoid subjecting the unit to mechanical stress

and prevent damage. Gas meters must be installed without any mechanical stress, preferably only by suspending them on the connectors. When using additional clamps, it must be ensured that no lateral forces act on the gas meter.

These can be avoided by using ﬂexible or supple

connection lines, for instance.

▷ If the calibration seal has been damaged or re-

moved, the gas meter is no longer approved for measurements which are subject to statutory testing.

▷ If the gas meter is stored or installed outdoors,

protect the site against rain. Condensing humid-

ity is permitted.

▷ Meters which are marked with H3 are suitable

for installation outdoors without additional protection.

 Remove protective caps.

▷

Installation in the vertical position: connectors must be pointing upwards.

▷ Note direction of ﬂow (arrow). ▷ The gas meter must not be in contact with ma-

sonry or other parts.

▷ Ensure that there is sufﬁcient installation space. ▷ Ensure unobstructed view of the index. ▷

The seal faces on the screw unions must be

clean and damage-free.

▷ Ensure that the seal is correctly seated.

Co-axial meters:

▷ The seal must be centred over the internal dia-

meter.

▷

Note the installation position of the pressure ring.

The inner beaded edge must point upwards.

▷ Replace damaged pressure rings when replac-

ing the meter.

Co-axial and two-pipe meters:

▷ For the compression of seals and the resulting

tightening torques for the screw unions, the seal

manufacturers’ speciﬁcations must be observed.

Tightening torques for the recommended ﬂat

seals in conjunction with screw connectors pursuant to DIN 3376-1 and 3376-2, see

instructions, Screw unions and tightening tor-

ques forBK-G1.6 toBK-G25)(D).

 Install the gas meter free of mechanical stress.

▷

If a pulse transmitter IN-Z6x is used for pulse tapping on the gas meter marked with – see

standard EN60079-14 (Explosive atmospheres).

Temperature test point

▷

Temperature sensors can be inserted into the thermowells for measuring the gas temperature

in the meter housing.

 Secure each of the temperature sensors using

the capstan screw provided.

Pressure test point on housing (optional)

▷

When using an elastomer seal, always use a pressure ring (shape A).
