P
rinciple of operation
T
he instrument is suitable for applications in liquids and bulk solids in
vessels under di
ffi
cult process conditions
.
T
here are application
possibilities in nearly all areas of industry
.
T
he limit level is detected contactlessly through the vessel wall
.
N
either a process
fi
tting nor a vessel opening is required
.
T
he
instrument is thus ideal for retro
fi
tting
.

.
T
he measuring principle has proven itself
well under extreme conditions because it measures contactlessly from
outside through the vessel wall
.
T
he measuring system ensures
maximum safety
,
reliability and plant availability independent of the
medium and its properties
