!
Note!
Within the upper and lower blocking distance, a reliable measurement can not be guaranteed.
For stilling well applications
The upper blocking distance (UB) is preset to 100 mm when the "bypass/pipe" parameter has been
selected in the "tank properties" (002) function.
Maximum measured error
Typical statements for reference conditions:
DIN EN 61298-2, percentage of the span.
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.
