Optional Configuration continued
CTL derivation methods
There are two derivation methods for CTL:
• Method 1 is based on observed density and observed temperature.
• Method 2 is based on a user-supplied reference density (or thermal expansion coefficient, in
some cases) and observed temperature.
API parameters
The API parameters are listed and defined in Table 8-2.
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.

Variable Description
Table type Specifies the table that will be used for reference temperature and reference density unit. Select
the table that matches your requirements. See API reference tables.
User defined TEC
(1)
(1) Configurable if Table type is set to 6C, 24C, or 54C.
Thermal expansion coefficient. Enter the value to be used in CTL calculation.
Temperature units
(2)
(2) In most cases, the temperature unit used by the API reference table should also be the temperature unit configured for the transmitter
to use in general processing. To configure the temperature unit, see Section 6.4.4.
Read-only. Displays the unit used for reference temperature in the reference table.
Density units Read-only. Displays the unit used for reference density in the reference table.
Reference
temperature
Read-only unless Table type is set to 53x or 54x. If configurable:
• Specify the reference temperature to be used in CTL calculation.
• Enter reference temperature in °C.
