4. Installation and commissioning / 5. Measuring arrangements

If the pressure transmitter is positioned lower than the pressure test

connection, the tailpipe has to be rinsed thoroughly prior to tting 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 sucient precautionary measures have to be

taken.
