Flow-X General functions - fxAPI_Table23_2004
Function
outputs Remark EU SW tag Alarm Fallback
Status 0: Normal
1: Input argument out of range
Outputs will be set to fallback
values
2: Calculation error
Outputs will be set to fallback
values
3: No convergence within 15 iterations
Outputs will be set to values of
last iteration
- 1
Relative
density
at 60 °F Relative density at 60°F and 0 psig - RD 0
CTL Volume correction factor for temperature.
Value will be rounded according to input
'API rounding' - CTL 1
CPL Volume correction factor for pressure
Value will be rounded according to input
'API rounding' - CPL 1
CTPL Combined volume correction factor
CTPL = CTL * CPL - CTPL 1
K0 Actual value of constant K0 used for CTL
calculation - K0 0
K1 Actual value of constant K1 used for CTL
calculation - K1 0
K2 Actual value of constant K2 used for CTL
calculation - K2 0
Alpha Thermal expansion factor 1/°F ALPHA 0
F Compressibility factor 1/psi F 0
Product When input 'Product' is 'B - Auto select',
then the output is set to the actual
selected product of table B (enumerative
value as defined for input 'Product'), else
the output is set equal to input 'Product'. - PRDCUR 0
Calculation
out of range With respect to the standard the input
values are:
0: In Range
1: Out of Range - OOR 0
Calculations
The calculations are in either full or partial compliance with the standard, depending on whether API
rounding is enabled or not.
