4. Commissioning, operation
Requirements for the installation point
If the line to the measuring instrument is not adequately stable, an instrument mounting
bracket should be used for fastening. The instruments should be protected against coarse dirt
and wide fluctuations in ambient temperature.

4.1 Mechanical mounting

The installation of the differential pressure gauge is made following the installation recom-
mendations for pressure measuring instruments in accordance with EN 837-2 /7.
Prior to the installation, clean the measuring lines thoroughly by tapping and blowing or
■
flushing.
Mount and operate the instruments free from vibration.
■
Fasten them using rigid measuring lines and/or 4 M8 mounting holes in the measuring
flange.
Protect pressure gauges from contamination and high temperature changes.
■
The maximum permissible medium/ambient temperature must not be exceeded.
■
Mounting of the process connection according to affixed symbols ⊕ and ⊖.
