Orientation for density
measurement
‣
The most constant conditions for density measurement in pipes are achieved if the unit is
mounted on vertical pipelines and the feed direction is from bottom to top. If only horizontal
pipes are accessible, the path of the beam should also be arranged horizontally to reduce the
influence of air bubbles and buildup. In order to achieve a longer path of the radiation through
the medium and thus a better measuring effect, a diagonal beam or a measurement section can
be used.

• Measurement section FHG62→ 56
Orientation of the fireproof
version
Orientation I (recommended)
The source container is mounted with the compensation compartment at the highest point. In the
event of fire only the emission channel is sealed by the liquefied lead.
NOTICE
‣
After a fire, the screening is slightly reduced in the upper area of the container

Orientation II (only if orientation I is not possible due to space restrictions)
The source container is mounted with the compensation compartment at the bottom or the side. In
the event of fire the emission channel and the compensation compartment are filled with liquefied
lead.
