Density (15°C) --> CTL
This function determines the volume correction factor for temperature CTL from the relative density
value at 15°C and the observed temperature according to the API 1952 Table 54.

Boundaries
Table 54 contains values for the following range:
Input value
Normal Range
EU
Density at 15 °C
500 .. 1100
kg/m3
Observed temperature
-50 .. +150
°C
Note that the table does not cover the full range, e.g. for a Density at 15 °C of 500 kg/m3the table only
specifies values between -50 .. 55 °C

Calculation out of
range
With respect to the standard the
input values are:
0: In Range
1: Out of Range
-
OOR
0
Calculations
The table values are the standard, so no calculations are involved. The function performs an
interpolation between the table values that correspond to the input specific gravity and input
temperature.
In case the combination of input values ('Specific gravity 60 °F' and Observed temperature') is not
covered by the table, the output 'CTL' is set to 1 and output 'Calculation out of range' is set to 1.
