6. Commissioning, operation
6.6 Permissible vibration load at the installation site
The instruments should always be installed in locations free from vibra-
tion.
If necessary, it is possible to isolate the instrument from the mounting
point, e.g. by installing a flexible connection line between the measuring
point and the pressure gauge and mounting the instrument on a suitable
bracket.
If this is not possible, the following limit values must not be exceeded:
Frequency range < 150 Hz
Acceleration < 0.5 g (approx. 5 m/s
6.7 Level check
For filled instruments, the level must be checked on a regular basis.
The liquid level must not drop below 75 % of the instrument diameter.
6.8 Commissioning
Pressure surges must be avoided at all costs, open the shut-off
„
valves slowly.
The instrument must not be subjected to any external loading (e.g.
„
use as a climbing aid, support for objects).
