Temperature Test Point; Connecting The Pressure Measuring Line; Tightness Test - Elster BK-G1.6 Operating Instructions Manual

▷ 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

Temperature test point

▷ Temperature sensors can be inserted into the
thermowells for measuring the gas temperature
in the meter housing.

WARNING
In 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 pro-
gressive ring fittings PSR/DPR.

nal diameter 6 mm, material E235 = 1.0308). For
other materials, use a suitable adapter and note
the Parker/EO recommendations.
▷ Install pipes free of mechanical stress.

8 Screw on the union nut by hand as far as it will
go.
▷ At the same time, press the end of the pipe firmly
against the stop.
9 Mark the position of the union nut and tighten
with about 1½ turns.
▷ When re-installing, the union nut will be turned
to the original position and then further tightened
through approx. 30°.
 Once the installation and tightness test are com-
plete, see page 4 (Tightness test), protect the
pressure 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. al-
lowable operating pressure p
meter. Otherwise, the installed gas meter may
be damaged.
▷ If a valve is integrated in the diaphragm gas me-
ter BK, see page 2 (Type label/Index plate), this
must be opened for the tightness test.
▷ Ensure the customer's consumers are closed.
