3. Pressure and temperature test points
Pressure and temperature test points are optional!
A straight male coupling in accordance with DIN 2353 is pre-fitted on the
meter housing for connection of a pressure sensor for instance.
The pressure test point is marked p
m
and is designed for connection of
d = 6 mm steel tubes in accordance with DIN EN 10305-1 (e.g. steel grade
E 235).
Do not connect the straight male coupling to pipes made of
stainless steel or pipes made of nonferrous materials.
The pressure test point is only present on meters with two temperature test
points!
You can use a maximum of two temperature sensors for measuring the gas
temperature in the meter housing. In order to achieve optimum thermal
conduction, you must fill the thermowells with a heat-conductive fluid or
paste.
4. Index / Index with check digit facility / Absolute ENCODER
The meter can be equipped with various index versions:
BK-G..E with index Z6
This is the standard version with an 8-digit
mechanical roller index.
Designed for LF pulse generators which can be
plugged on from the outside and which can be
exchanged on site.
BK-G…C with index Z6 with check digit facility
(CHEKKER®)
This has the same features as index Z6.
In addition, it also has a 2-digit check digit, which
is set up in a particular ratio to the meter reading
and which checks whether the read value and the
device number are correct. A software package is
installed in the data logging unit, which enables
the test process (decoding).
