Micropilot FMR62
76 Endress+Hauser
The 5 points of the linearity protocol are evenly distributed over the measuring range (0 to 100 %).
The Empty calibration (E) and Full calibration (F) must be specified to define the measuring range .
If this information is missing, antenna-dependent default values are used instead.
The following restrictions must be considered when selecting E and F:
A0032286
R Reference point of measurement
A Minimum distance between reference point R and 100% mark
E Empty calibration
F Full calibration
Minimum distance between reference point R and
100% mark
Minimum span Maximum value for "Empty
calibration"
A ≥ length of antenna + 200 mm (8 in)
Minimum value: 400 mm (16 in)
F ≥400 mm (16 in) E ≤24 m (79 ft)
• The linearity check is performed under reference operating conditions.
• The values selected for Empty calibration and Full calibration are only used to create the
linearity protocol. Afterwards, the values are reset to the default values specific for the
antenna. If values other than the default values are required, they must be ordered as a
customized parameterization.
Customer-specific
configuration
Default settings that deviate from the standard can be selected for the following parameters if the
option: IJ (customized configuration, HART), IK (customized configuration, PA) or IL (customized
configuration, FF) is selected in feature 570 (service):
