Mounting instructions

Installation position
When mounting the transmitter, keep a distance of at least 200 mm (7.874 in) from
the vessel wall. If the transmitter is installed in the center of dished or round vessel
tops, multiple echoes can arise. However, these can be suppressed by an appropriate
adjustment (see chapter "Setup").
If you cannot maintain this distance, you should carry out a auto false echo suppres-
sion during setup. This applies particularly if buildup on the vessel wall is expected. In
such cases, we recommend repeating the auto false echo suppression at a later date
with existing buildup.
