4. Installation and commissioning / 5. Measuring arrangements
Installation using
a spanner
If the pressure transmitter is positioned lower than the pressure test
connection, the tailpipe has to be rinsed thoroughly prior to fitting the gauge
to remove all foreign substances.
Once the pressure and electrical connections have been made, the trans-
mitter is ready for immediate use.
Before dismounting the pressure instrument the measuring element has to
be depressurized. Eventually the stress of the pipe has to be relieved.
Residual pressure medium remaining within the pressure
element may cause harm to men, facilities and environment.
Therefore sufficient precautionary measures have to be
taken.
