2.2 Appropriate use
When in operating mode, the source container VEGASOURCE 81 de-
scribed in this document contains a radiactive source for radiometric
level, interface, switching and density measurement as well as mass
flow detection. The source container shields the radiation off from the
surroundings and only allows it to exit, practically unhindered, in the
direction of measurement.
To ensure the shielding effect and exclude damage to the radioactive
source, all instructions in this operating instructions manual and the
legal radiation protection regulations must be observed during instal-
lation and operation.
Operational reliability is ensured only if the instrument is used prop-
erly. We are not liable for damages caused by improper use.
You can find detailed information about the area of application in
chapter " Product description ".
