truncating rules are applied
and the table value for CTL
as specified in the standard
meaning that the CTL value
has 4 decimal places in all
cases
3: Enabled with 5 decimal places
API-2540 rounding and
truncating rules are
applied, while the CTL
value has 5 decimal places
in all cases.
Note: although not strictly
in accordance with the
standard, this option is
more commonly used than
option 'Enabled for
computational value'
Function
outputs Remark EU SW tag Alarm Fallback
Status 0: Normal

2: Calculation error
- STS
FIOOR
CALCERR
CTL Volume correction factor for
temperature.
Value will be rounded according to input
'API2540 rounding' - CTL 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
Product When input 'Product' is 'B - Auto select',
then the output is set to the actual
selected product of table 24B
(enumerative value as defined for input
'Product'), else the output is set equal to
input 'Product'. - PRDCUR Input
Product
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 full or partial compliance with the standard depending on input ‘API 2540
rounding’.
