3.9 Commissioning
3.9.1
Filling with oil
Notice
When the turbine meters are delivered, the lubricators do not contain any
oil.
The oil pumps must not be filled with oil until they are at the installation
site prior to commissioning!
A small bottle of oil is supplied with each gas meter. Then you have to
perform an initial lubrication. For this see the detailed lubrication instruc-
tions in chapter 4.2 Lubrication.
3.9.2
Connecting the gas flow
Warning
Do not fill any downstream pipelines or station sections through the
turbine meter. This may speed up the turbine wheel and lead to
excessively high loads with resultant damage.
Notice
Short-time overload operation of 20% above the maximum flow rate Q
max
is
permissible. Such load conditions should be avoided, however, since in
most cases they cannot be controlled and exceed the officially approved
limits for custody transfer metering. Moreover, such overloads reduce the
service life of the gas meter.
Warning
The gas flow must be free of foreign particles, dust or liquids. Otherwise it
is recommended that filters or separators be installed.
