Control Word (CTW)- Select Products
The type of product should be selected in this field. Available products are crude oil, generalized
products, MTBE and lubricating oil. Once the inputs and product are selected, we have the table
that will be used in the calculations.
Control Word (CTW)- Select Output
The user should set the type of the output. There are 2 options:
VCF
CCF
Tables
Once the user has set inputs, product and output will have to be implicitly set a table of the API
standard.
Input Scale Conversion Factors Conversion
The Input scale has two factors (parameters the user must set) to convert these parameters to
engineering units (EU). IN1 input must be adjusted through the parameters K1 (GAIN) and K2
(BIAS). Similarly IN2 input must be set through parameters K3 (GAIN) and K4 (BIAS). After
conversion they will be in the following format:
Density (EU)= IN1*K1+K2
Temperature (EU)=IN2*K3+K4
Pressure (EU)=IN3*LOW+HIGH
