API tables supported by the API referral application
The API tables listed here are supported by the API referral application.
Table 4-5: API tables, process fluids, measurement units, and default reference values
Process fluid
Generalized crude and JP4
Generalized products (gasoline, jet
fuel, aviation fuel, kerosene, heat-
ing oils, fuel oils, diesel, gas oil)
Configuration and Use Manual
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, and reference temperature 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.
If you chose a C table, enter Thermal Expansion Coefficient (TEC) for your process fluid.
Refer to the API documentation and confirm your table selection.
a. Verify that your process fluid falls within range for line density and line
temperature.
If your process fluid goes outside any of these limits, the meter will post a status
alert and will report extrapolated values for referred density.
b. Verify that the referred density range of the selected table is adequate for your
application.
If required, set Ref Temperature to the temperature to which density will be corrected
in referred density calculations.
The default reference temperature is determined by the selected API table.
a. Choose Service Tools > Maintenance > Modbus Data > Write Modbus Data.
b. Write the desired reference temperature to Registers 319–320, in the
measurement unit required by the selected API table. Use 32-bit IEEE floating-
point format.
