a Angle of aperture
For level detection, the version of the source container with an exit
angle of a = 5° is suitable. The radiation must be directed exactly
towards the detector mounted on the opposite side.
If you want to use larger exit angles (20° or 40°), you have to make
sure the beam is horizontal. To do this you have to mount the source
container so that the eye-bolt is in a horizontal position.
The source container VEGASOURCE should be mounted as close as
possible to the vessel.
However, a distance can often not be avoided with large measuring
ranges and small vessel diameters.
If there are gaps or intervening spaces around the installation, provide
protective fences or grids to keep hands away from the dangerous
area. Such areas must be marked accordingly.
