Selection: Standard Fast change Slow change Test: no filter
Application: For all normal applications,
bu lk solids and fl u ids at
low to medi u m filling speed
and s u fficiently large
tanks.
Small tanks, primarily with
fl
u ids, at high filling
speeds.
Applications with strong
s
u rface movement, e. g.
ca u sed b y stirrer, primarily
large tanks with slow to
medi
u m filling speed.
Shortest reaction time:
- For test p
u rposes
- Meas u rement in small
tanks at high filling
speeds, if "rapid
change" setting is too
slow.
