2. Choose
API Referral Setup
.
3. Specify the API table that you want to use to calculate referred density.
Each API table is associated with a specific set of equations.
a) Set
API Table Number
to the number that matches the API table units that you want to use for
referred density.
Your choice also determines the measurement unit to be used for temperature and pressure,
and the default values for reference temperature and reference pressure.

Generalized products: Gasoline, jet fuel, aviation fuel, kerosene, heating oils,
fuel oils, diesel, gas oil
Liquids with a constant base density or known thermal expansion coefficient
(TEC). You will be required to enter the TEC for your process fluid.

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).
