intelligent filter.
Selection:
• standard
• fast change
• slow change
• test: no filter

Selection: standard fast change slow change test: no filter
Application: For all normal applicati-
ons, bulk solids and flu-
ids at low to medium
filling speed and suffi-
ciently large tanks.
Small tanks, primarily
with fluids, at high fil-
ling speeds.
Applications with
strong surface move-
ment, e.g. coused by
stirrer, primarily large
tanks with slow to
medium filling speed.
Shortest reaction time:
• For test purposes
•Measurement in
small tanks at high
filling speeds, if
"rapid change" set-
ting is too slow.
