In thermodynamics, the Volume Correction Factor (VCF), also known as Correction for the effect of Temperature on Liquid (CTL), is a standardized computed factor used to correct for the thermal expansion of fluids, primarily, liquid hydrocarbons at various temperatures and densities. [1]

Density at 15 °C = 840 kg/m 3 (table 54B) Refer to bulletin V-18 for more information on product classes. Volume correction factors to 15 °C for use with all grades of diesel, bio-diesel and diesel blends (including B100)

Traditionally, CTL/VCF values are found in books/tables provided by the American Petroleum Institute, matching the temperature and density to find the CTL/VCF values. Such methods are often time-consuming and tedious. The calculator below omits the tables and computes the required values for you.

Sep 23, 2018 · ASTM tables give the Volume correction factors (VCF) to find the volumes at temperature for which the density is given. Let us say cargo surveyor provided the density at 15 deg C as 0.816 and ASTM table 54B to be used.

The Volume Correction Factor (VCF) is the factor depending on the oil type, density or its equivalent and temperature which corrects oil volumes to the Standard Reference Temperature (s). (ASTM Tables 54 A, B, C, D or 6 A, B)

TABLE 54B, Generalized Products, Correction of volume to 15°C against density at 15°C DEN15 Density at 15°C DEGC Observed Temperature, °C ALPHA Coefficient of thermal expansion ... VCF: 0.988067 EXAMPLE 4 DEN15: 819 DEGC: 26.75 ALPHA: 0.0008864 VCF: 0.989552 . EXAMPLE 5 DEN15: 777.5 (Transition zone) DEGC: 9 ALPHA: 0.0010708

Enter the density (API Gravity, Relative Density or Density) at standard temperature (60°F or 15°C) and the temperature (°F or °C) into the according input fields. After pressing the “Calculate” button the input parameters are rounded according to ASTM 1250 and the Volume Correction Factor is shown.

Using the calculator below, enter the Temperature in degrees Fahrenheit (°F), and the Density in Degrees API. These two numbers will be computed with the coefficient of thermal expansion at 60°F (α₆₀) based on the selected commodity and return the CTL/VCF Value.

ThermoTab is a Free application to calculate Volume Correction Factors for generalized crude oil, refined products and lubricating oils according to Manual for Petroleum Measurement Standard API Chapter 11.2 2004. ASTM D1250-04. IP 200/04.
