4. If the concentration measurement application is displayed in the list, choose
Concentration
Measurement
and ensure that
Enabled/Disabled
is set to Disabled.
The concentration measurement application and the API referral application cannot be enabled
simultaneously.
5. Enable API referral.
a) Choose
Menu
>
Configuration
>
Process Measurement
>
API Referral
.
b) Set
Enabled/Disabled
to Enabled.

Configure API referral using the display
The API referral parameters specify the API table, measurement units, and reference values to be used in
referred density calculations.
Prerequisites
You will need API documentation for the API table that you select.
Depending on your API table, you may need to know the thermal expansion coefficient (TEC) for your process
fluid.
You must know the reference temperature and reference pressure that you want to use.
Procedure
1. Choose
Menu
>
Configure
>
Process Measurement
>
API Referral
.
2. Set
API Table
to the API table that you want to use to calculate referred density.
Each API table is associated with a specific set of equations. Choose your API table based on your
process fluid and the measurement unit that you want to use for referred density.
Your choice also determines the API table that will be used to calculate the correction factor for volume
(CTPL or CTL).
3. Refer to the API documentation and confirm your table selection.
a) Verify that your process fluid falls within range for line density, line temperature, and line
pressure.
b) Verify that the referred density range of the selected table is adequate for your application.
4. If you chose a C table, enter
Thermal Expansion Coefficient (TEC)
for your process fluid.
5. If required, set
Reference Temperature
to the temperature to which density will be corrected in
referred density calculations.
The default reference temperature is determined by the selected API table.
6. If required, set
Reference Pressure
to the pressure to which density will be corrected in referred
density calculations.
The default reference pressure is determined by the selected API table.
