Levelflex M FMP43 with FOUNDATION Fieldbus
Tank internals
• If the distance to the internals is < 300
mm, "mapping" must be carried out, and
the measurement capability may be
restricted.
• During operation, the probe must not
touch any internals within the measuring
range.
Optimization options
• Interference echo suppression:
measurement can be optimized by
electronically suppressing interference
echoes.
!
Note!
You must ensure that the probe does not come into contact with the container wall, container
bottom and tank internals.
2.2.3 Special instructions
When installing in tanks with agitator, observe the lateral loading capacity of rod probes:
• 10 Nm with 1.4435 / SS316L
• 16 Nm with Hasteloy C22 (auf Anfrage).
