5.1.5 Process variables from the API referral application
The API referral application calculates several different process variables according to API standards.
CTPL Correction factor based on line temperature and line pressure. CTPL is applied when
the API referral application is configured for an A, B, C, or D table.
CTL Correction factor based on line temperature and pressure at saturation conditions.
CTL is applied when the API referral application is configured for an E table.
Referred density The measured density after CTL or CTPL has been applied.
API volume flow The measured volume flow rate after CTL or CTPL has been applied. Also called
temperature-corrected volume flow.
Batch-weighted One density value is recorded for each unit of flow (e.g., barrel, liter). The average is
average density calculated from these values. The average is reset when the API totalizer is reset. Not
available unless a totalizer has been configured with Source set to Temperature-
Corrected Volume Flow.
Batch-weighted One temperature value is recorded for each unit of flow (e.g., barrel, liter). The
average average is calculated from these values. The average is reset when the API totalizer is
temperature reset. Not available unless a totalizer has been configured with Source set to
Temperature-Corrected Volume Flow.
API volume total The total API volume measured by the transmitter since the last API totalizer reset.
Also called temperature-corrected volume total. Not available unless a totalizer has
been configured with Source set to Temperature-Corrected Volume Flow.
API volume The total API volume measured by the transmitter since the last API inventory reset.
inventory Also called temperature-corrected volume inventory. Not available unless an inventory
has been configured with Source set to Temperature-Corrected Volume Flow.

5.2 Set up concentration measurement

The concentration measurement application calculates concentration from line density and line temperature.
5.2.1 Preparing to set up concentration measurement
The procedure for setting up concentration measurement application depends on how your device was
ordered and how you want to use the application. Review this information before you begin.
Requirements for concentration measurement
To use the concentration measurement application, the following conditions must be met:
• The concentration measurement application must be enabled.
• The API Referral application must be disabled.
• The advanced phase measurement application must be disabled.
• A concentration matrix must be loaded into one of the six slots on the transmitter.
Tip
In most cases, the concentration matrix that you ordered was loaded at the factory. If it was not, you have
several options for loading a matrix. You can also build a matrix.
