Levelflex M FMP41C 4...20 mA HART
Maximum measured error
Typical statements for reference conditions:
DIN EN 61298-2, percentage of the span.
Output:
sum of non-linearity,
non-repeatabilityand hysteresis
Offset / Zero
If the reference conditions are not met, the offset/zero arising from the mounting situation may
be up to ±12 mm. This additional offset/zero can be compensated for by entering a correction
(function "offset" (057))during commissioning.
Differing from this , the following measuring error is present in the vicinity of the probe end:

Note!
Please reenter the blocking distance in the function group "extended calibr." (05) function
"upper block dist." (059) when installing the device in a high nozzle: upper blocking distance
(UB) = nozzle height (H) + 50 mm.
