•
Install the level transmitter in a metal bypass or a metal still pipe.
•
Separate the level transmitter location with metal sheets or perforated sheets.

)
Note
The upper access to the steady area (A, B) must be above the maximum level. The lower
access (C, D) or the area with perforated sheet must be below the minimum level. This
ensures that neither foam nor turbulence impact the transmitter zone. To avoid
interference from solids in the medium, use perforated sheets or something similar.
Note
With increased foam build-up set the medium parameter [MEdI] to [MId]. For instructions,
see
2.1.7
Tank adjustment
Tank adjustment reduces interference and ensures a higher excess gain in difficult
application conditions.
CAUTION
Perform a tank adjustment only after installing the level transmitter.
•
When performing a tank adjustment, enter an adjustment distance first. Starting from
the process connection, use the adjustment distance to compensate for interfering
reflections.
•
Select an adjustment distance (a) so the level transmitter can detect the connection
piece (S) and structures in the tank (B).
•
Observe safety distance (b ≥ 9.84 in (250 mm)) to the level or the probe end.
