Density Meter LB 444 SECTION 3. INSTALLATION
31
Installation in a Container or Tank
If density measurements are made in a container, the source is installed in a
special lead shielding in a protection tube inside the container. Special care
must be taken to ensure that bending the protection pipe does not alter the
measuring path, as this leads to significant measurement errors. A brace may
be required for very long protection tubes. The material of the protection pipe
must be resistant to the product being measured.

The installation has to be done such that the radiation path lies diagonally to the
flow direction. With horizontal flow the radiation exit channel should point toward
the bottom to prevent deposit formation in the path of radiation.
