Figure B‐18. Arithmetic Function Block Schematic
Different fluids over the same temperature range have different effects on level due to their thermal expansion
coefficients. Vessel geometry also plays a major role. As the height of the vessel increases, the effect of thermal
expansion becomes more apparent. Figure B‐19 shows the relative temperature effects on a level signal.
Figure B‐19. Relative Temperature Effects on Level
The calculation is done by applying the level signal to the IN connector, the liquid temperature to the IN_1 connector,
and the ambient air temperature to the IN_2 connector. Select the Arithmetic type (ARITH_TYPE) of Flow
