4.3 Mounting Orientation
Prior to mounting the SHLD 2, make certain the orientation of the source holder
is correct.
Continuous Level Orientation
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 opposite side.
The source holder SHLD 2 should be mounted as close as possible to the vessel.
However, with large measuring ranges and small vessel diameters, a gap can
often is not avoidable
.
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.
Align the source holder according to its beam exit angle.
