Exchange of a parabolic antenna / flange for FMR 533
Calibration of the Micropilot S
Antenna / electronics and HF module are paired and can therefore not be exchanged separately. Thus, a specific basic calibration does not apply.
An exchange of individual components in a workshop for an error analysis in case of a repair is possible, however, installation of a “wrong” assembly
leads to significant measuring errors considerably outside the specifications.
After the instrument has been installed according to the instructions, it has to be aligned for its electrical field (see chapter "Alignment of installed instrument")
and to be newly configured.
In case all parameters have been stored from the original calibration (upload), a download saves the complete new calibration process.
Preparation for a level calibration
FMR 533 after exchange of parabolic antenna
Instrument is assembled
and mounted on tank
It is recommended to reset the instrument to the factory settings
before the calibration:
enter 333 in field 0A3 of the diagnostics level.
The configuration should be locked against unwanted changes:
enter a value < > 100 in field 0A4 in the diagnostics level.
For operation calibrated to legal standards (according to OIML R85),
access to the electronics must be locked with the lock switch, which has
to be sealed by an official.
Perform basic setup according to manual.
Observe the difference between free field antenna
and stilling well antenna.
A requirement for mm-accuracy (for calibration to legal standards)
is the reset of the history:
enter 555 in field 0A3 of the diagnostics level.
End
when using a Tank Side Monitor, further
compensation is possible
(i.e. pressure, temperature, etc.)
total reset for HART: 7864
the index correction table and the
table for automatic micro-factor
determination are reset.
