Emerson Process Management 2400S manual API reference tables

Optional Configuration

API reference tables

Reference tables are organized by reference temperature, CTL derivation method, liquid type, and density unit. The table selected here controls all the remaining options.

•Reference temperature:

-If you specify a 5x, 6x, 23x, or 24x table, the default reference temperature is 60 °F, and cannot be changed.

-If you specify a 53x or 54x table, the default reference temperature is 15 °C. However, you can change the reference temperature, as recommended in some locations (for example, to 14.0 or 14.5 °C).

•CTL derivation method:

-If you specify an odd-numbered table (5, 23, or 53), CTL will be derived using method 1 described above.

-If you specify an even-numbered table (6, 24, or 54), CTL will be derived using method 2 described above.

•The letters A, B, C, or D that are used to terminate table names define the type of liquid that the table is designed for:

-A tables are used with generalized crude and JP4 applications.

-B tables are used with generalized products.

-C tables are used with liquids with a constant base density or known thermal expansion coefficient.

-D tables are used with lubricating oils.

•Different tables use different density units:

-Degrees API

-Relative density (SG)

-Base density (kg/m3)
