UPDATING PHYSICAL PROPERTY CORRELATIONS WITH LABORATORY DATA

摘要

In a control logic system (10) for updating physical property correlations, the difference between a calculated value (14) of a physical property and a laboratory value (12) of the physical property is determined (16) and combined (20) with a previously determined value (28) of the difference to obtain a new value of the correlation bias. Actuation of remote switches (30, 32) by a system operator allows this new value or correlation bias to pass through the control system and be "set" until an updated correlation bias is desired by the operator.
