Checking the usage

Diaphragm gas meters BK-G1.6 to G5Residential or commercial diaphragm gas meters BK for recording gas consumption values for natural gas, town gas, propane and butane, 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 atmosphereDiaphragm gas meters that are labelled with and

(see sticker next to the index) are suitable for operation in potentially explosive atmospheres of Category 2G (Zone 1) of Class II 2G c IIB (TÜV 09 ATEX 554884X), see [Declaration of conformity – p. 6].

This function is only guaranteed when used under the specified operating conditions – see [Technical data – p. 5]. Any other use is considered as non-compliant.

Installation

WARNINGPlease observe the following to ensure that neither persons nor the gas meter are damaged during installation and operation:– Note the max. allowable operating pressure pmax.

and measuring range Qmax., see [Type label/Index plate – p. 2].

– Note the permitted ambient temperature tm and gas temperature tg, see [Type label/Index plate – p. 2] or [Technical data – p. 5].

– The gas meter is suitable for mechanical ambient conditions of Class M1 of Directive 2004/22/EC. For gas meters with an Absolute ENCODER index, Class E2 for electromagnetic ambient conditions also applies.

– When installing the diaphragm gas meter BK with integrated “Smart 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.

– For meters resistant to high temperatures, only use seals tested to be resistant to high tempera-tures.

– Only use the seals once.– For installation and operation, note the applicable

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

– 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 humidity is permitted.

1 Remove protective caps.▷▷ Installation in the horizontal 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.▷▷ 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 www.docuthek.com →▷Elster-Instromet →▷Products →▷Gas measuring

devices → Diaphragm meters → Ergänzung für Betriebsanleitung BK, Verschraubungen und An-zugsmomente für BK-G1,6 bis BK-G25 (Supple-ment for BK operating instructions, Screw unions and tightening torques for BK-G1.6 to BK-G25) (D).

Install the gas meter free of mechanical stress.

▷▷ The gas meter marked with must be included in the equipotential bond when being installed in a potentially explosive atmosphere, e.g. by con-necting it to a grounded pipeline.▷▷ If a pulse sensor IN-Z6x is used for pulse tap-

ping on the gas meter marked with – see Data sheet for pulse sensor IN-Z6x (D, GB) www.docuthek.com → Elster-Instromet → Prod-ucts → Gas measuring devices → Diaphragm meters →▷Pulse sensor IN-Z61 and the 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.

1 2

Secure each of the temperature sensors using the capstan screw provided.

Connecting the pressure measuring line

WARNINGIn order to ensure that the gas meter is tight:– The pressure test nipple must not be twisted, bent,

or otherwise manipulated.– When installing, always secure the pressure test

nipple using a suitable spanner.

▷▷ Functional safety and reliability are ensured only if the material combination of the screw connector and the pressure line are intermatched.▷▷ Only use the olive and the attached union nut

supplied. The olive is secured to the sealing sleeve.▷▷ When re-ordering, use original Parker EO progres-

sive ring fittings PSR/DPR.

▷▷ When re-installing, the union nut will be turned to the original position and then further tightened through approx. 30°.

11 Once the installation and tightness test are com-plete, see [Tightness test – p. 4], protect the pres-sure test point against external access with the sealing sleeve and the seal.

Tightness test▷▷ Check the pipework for leaks prior to installation of

the gas meter, in case the pipework is tested with a greater test pressure than the max. allowable operating pressure pmax. for the gas meter. Oth-erwise, the installed gas meter may be damaged.▷▷ If a valve is integrated in the diaphragm gas meter

BK, see [Type label/Index plate – p. 2], this must be opened for the tightness test.▷▷ Ensure the customer’s consumers are closed,

see [Diaphragm gas meters BK with integrated “Smart Valve” – p. 5].

to the diaphragm gas meter, check this connec-tion for tightness.

to the diaphragm gas meter, protect the pressure test point against external access with a sealing sleeve and a seal.

CommissioningOnce the tightness test has been successfully com-pleted, the gas meter is ready for operation.▷▷ Slowly open the manual valve.

Diaphragm gas meters BK with integrated “Smart Valve”In the event that the diaphragm gas meter BK is fittedwith an integrated “Smart Valve”, see „Type label/Index plate“ auf Seite 2, the gas supply can be con-nectedor disconnected remotely.

WARNINGThe network provider is responsible for the safe remote shut-down and restart of the diaphragm gas meter:– The “Smart Valve” does not assume the safety

functions of a safety shut-off valve.– Depending on national regulations, a limited and

technically safe gas flow rate in the customer’s open consumer piping is allowed, see [Technical data – p. 5].

– 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 [Technical data – p. 5]. 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 functionThe “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 downstream installation is tight.

ReleasedThe “Smart Valve” opens an internal bypass and releases a minimum gas flow into the customer’s closed consumer piping. Pressure equalization takes place between the inlet and outlet side of the valve.

OpenFollowing pressure equalization, the valve automati-cally opens by spring force and fully releases the gas supply. If consumers of the customer are open, pressure equalization cannot occur and the valve remains in the “Released” position and continues to release only the minimum gas flow rate of the bypass.

ClosedThe valve and the bypass are closed in the event of remote shut-down.▷▷ All valve positions are kept de-energized.

Maintenance/RemovalGas meters BK-G1.6 to 25 from Elster are mainte-nance-free.▷▷ When used for custody transfer measurements,

recalibration must be carried out in accordance with national Directives.▷▷ If the screw unions are loosened for maintenance

work or retesting, replace the seals.▷▷ After the gas meter has been removed, immedi-

ately close the connectors with protective caps, in order to prevent an ingress of dirt particles.

WARNINGA certain amount of gas may remain in the gas meter. Taking into consideration the risk of explo-sion, it is important to adopt safety measures, e.g.:– Following removal of the gas meter, purge it thor-

oughly with inert gas.– For transporting the gas meter with gas residue,

use a vehicle with an open or a ventilated loading area.
