6.6 Permissible vibration load at the installation site
The instruments should always be installed in locations free from
vibration.
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).
