Output
Possible cause
Remedy
If the surface is not
calm (e.g. filling,
emptying, agitator
running), the
measured value
jumps sporadically
to a higher level
L00-FMR53xxx-19-00-00-en-008
Signal is weakened by
the rough surface — the
interference echoes
are sometimes stronger
1.
Carry out tank mapping
→
basic
setup
2.
Set the process cond. (004) to
"turb. surface" or "agitator
3.
Increase the output damping
(058)
4.
Optimise the orientation
(see Page 75)
5.
If necessary, select a better
mounting position and/or larger
antenna (see Page 15)
During filling/
emptying the
measured value
jumps sporadically
to a higher/lower
level
L00-FMR53xxx-19-00-00-en-009
During definition of the
auto correction table
the instrument has been
switched off and the
level has changed.
1.
Reset "555"
2.
Iff possible, do not switch off the
instrument before the complete
measuring range has been passed
through.
During filling/
emptying the
measured value
jumps downwards
L00-FMR53xxx-19-00-00-en-004
Multiple echoes
yes
→
1.
Check the tank shape (002),
e.g. "dome ceiling" or
"horizontal cyl"
2.
In the range of the blocking dist.
(059) there is no echo evaluation
→
Adapt the value
3.
If possible, do not select
central installation position
(see Page 15)
4.
Activate auto correktion (031)
E 641 ((loss
ofecho)
L00-FMR53xxx-19-00-00-en-005
Level echo is tooweak.
Possible causes:
• Rough surface dueto
filling/emptying
• Agitator running
• Foam
yes
→
1.
Check application parameters
(002), (003) and (004)
2.
Optimise alignment
(see Page 75)
3.
If necessary, select a better
installation position and/or larger
antenna (see Page 15)
