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 that you want to use.
Procedure
1. Choose Device Tools > Configuration > Process Measurement > Petroleum
Measurement.
2. Specify the API table to use to calculate referred density.
Each API table is associated with a specific set of equations.
a. Set Process Fluid to the API table group that your process fluid belongs to.
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
b. Set Referred Density Measurement Unit to the measurement units that you want
to use for referred density.
c. Click Apply.
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 (CTL).
Restriction
Not all combinations are supported by the petroleum measurement 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.
