4.2 Mounting instructions
Note:
Along with the planning, our specialists will analyse the conditions of
the measurement loop to dimension the radiation source (isotope)
accordingly.
You get a "Source Sizing" document specifying the required source
activity and containing all relevant mounting information for your
measuring point.
You must follow the instructions of this "Source Sizing" document in
addition to the following mounting instructions.
The following mounting information is applicable as long as there is
nothing else specified in the "Source Sizing" document.

You can find information on protective barriers and the mounting
of the corresponding source container in the operating instructions
manual of the source container, e.g. VEGASOURCE.
For level detection, the sensor is generally mounted horizontally at the
height of the requested limit level. Make sure that there are no struts
or reinforcements at this position in the vessel.
Direct the exit beam of the source container exactly towards the
measuring range of POINTRAC 31.
Fasten the sensor in such a way that it cannot fall out of the holder. If
necessary, provide the sensor with a support from below.
Mount the source container and POINTRAC 31 as close as possible
to the vessel. If there are gaps, secure the area with a safety fence
