The API referral application must be enabled before you can perform any setup. If the API referral application
was enabled at the factory, you do not need to enable it now.
Prerequisites
The API referral application must be licensed on your transmitter.
Volume Flow Type
must be set to Liquid.

Volume
Flow Type
is set to Liquid.
This parameter is available only if API referral or concentration measurement is not enabled. If you do
not see this parameter, it is already set correctly.
2. If the concentration measurement application is enabled, disable it.
The concentration measurement application and the API referral application cannot be enabled
simultaneously.
3. Enable the API referral application.

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.
