API table group Process fluids
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)
Note
The API referral application is not appropriate for the following process fluids: ethanol,
butadiene and butadiene mixes, isopentane, LNG, ethylene, propylene, cyclohexane,
aeromatics, asphalts, and road tars.
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. 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.
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.
If your process fluid goes outside any of these limits, the meter will post a status
alert and will report line density instead of referred density until the process fluid
goes back within range.
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.
