- Dynamic
Measurement with Automatic Sampler
The indicated volume is
corrected by the composite correction factor to give TCV. The
S&W is subsequently applied to obtain the NSV.
-
Dynamic Measurement Without Automatic Sampler
The free water is subtracted
from the TCV to obtain the GSV. The S&W is then
applied to the GSV to obtain the NSV. The values of free
water and S&W should be determined from a consistent, mutually
agreed upon source.

The current API volume
correction factor tables should be used for all calculations.
If any party in the transaction has used a different set of volume
correction factors, this fact should be noted and the alternative
calculations should be included in the inspection report.
Sediment and water amounts in
heavy fuels and residuals usually not deducted unless they exceed 1
percent of the total volume. Contractual agreements, however,
determine the method of testing and S&W determination.
