Figure 7-27 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 Compensation - Linear.
This allows a ratio to be set up that increases the level indication at block output for an increase
in the tank temperature relative to ambient temperature.

This application can be applied to very large storage tanks whose contents are subject to
thermal expansion and contraction during seasonal changes in temperature.
