The pneumatic actuator must not be used under ambient conditions
that can cause corrosion in and on the pneumatic actuator.
4.2 Mounting instructions
For continuous level measurement the source holder must be
mounted slightly above or at the height of the max. level. The radiation
must be directed exactly towards the detector mounted on the op-
posite side.
The source holder VEGASOURCE should be mounted as close as
possible to the vessel.
However, with large measuring ranges and small vessel diameters, a
gap can often not be avoided.
If there are gaps or empty spaces around the installation, provide
protective fences or grids to keep hands away from the dangerous
area. Such areas must be marked accordingly.
