(1) Used only with API Table Letter = C.
(2) Used only with API Table Letter = E.
b) Set API Table Letter to the letter of the API table group that is appropriate for your process fluid.
API table letter
Process fluids
A Generalized crude and JP4
B Generalized products: Gasoline, jet fuel, aviation fuel, kerosene, heating oils,
fuel oils, diesel, gas oil
C
(1)
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 Lubricating oils
E
(2)
NGL (Natural Gas Liquids) and LPG (Liquid Petroleum Gas)
(1) Used only with API Table Number = 6, 24, or 54.
(2) Used only with API Table Number = 23, 24, 53, 54, 59, or 60.
API Table Number and API Table Letter uniquely identify the API table. The selected API table is
displayed, and the meter automatically changes the density unit, temperature unit, pressure unit,
reference temperature, 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.
4. If you chose a C table, enter Thermal Expansion Coefficient (TEC) for your process fluid.
Acceptable limits:
• 230.0 x 10
-6
to 930.0 x 10

per °F
• 414.0 x 10

5. 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.
