CAUTION
•
When a tank filling (
Xn
) does not reach 100% of the height of the tank, the transmitter will calculate the
remaining part. This calculating method is linear and will only be used for the remaining part up to 100%.
Linearized Filling
Linear calculation up to 100%
•
It is not advisable to manually adjust the SPAN in program point P102 after a linearization has been
configured. If the SPAN is adjusted after a linearization configuration, a warning will appear on the screen
when entering P102.
•
When the a free linearization is used for measuring weight (Kg and Tons), a reliable accuracy cannot be
guaranteed due to external influences such as heat and tank wall expansion.
The change of Specific
Gravity due to different temperatures cannot be compensated by the pressure transmitter.
n
Simulation
After linearization is entered and saved, it is possible to perform a simulation. (Based on the saved linearization)
The transmitter will convert the entered mWc to hectoliters.
6.12 Burst Mode
The transmitter can be configured for Burst mode.
This
will enable continuously broadcasting standard
HART reply messages.
