API table group
Process fluids
A tables
Generalized crude and JP4
B tables
Generalized products: Gasoline, jet fuel, aviation fuel, kerosene, heating oils,
fuel oils, diesel, gas oil
C tables
Liquids with a constant base density or known thermal expansion coefficient
(TEC). You will be required to enter the TEC for your process fluid.
D tables
Lubricating oils
E tables
NGL (Natural Gas Liquids) and LPG (Liquid Petroleum Gas)
b) Set
Referred Density Measurement Unit
to the measurement units that you want to use for
referred density.
c) Click

.
These parameters uniquely identify the API table to be used to calculate referred density. The selected
API table is displayed, and the meter automatically changes the density unit, temperature unit,
pressure unit, and reference pressure to match the API table.
Your choice also determines the API table that will be used to calculate the correction factor for volume
(CTPL or CTL).
Restriction
Not all combinations are supported by the API referral application. See the list of API tables in this
manual.
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. Set
Reference Temperature
to the temperature to which density will be corrected in referred density
calculations. If you choose Other, select the temperature measurement unit and enter the reference
temperature.
6. Set
Reference Pressure
to the pressure to which density will be corrected in referred density
calculations.

Set up temperature and pressure data for API referral using ProLink III
The API referral application uses temperature and, optionally, pressure data in its calculations. You must
decide how to provide this data, then perform the required configuration and setup.
Tip
Fixed values for temperature or pressure are not recommended. Using a fixed temperature or pressure value
may produce inaccurate process data.
