scope:

This section of API MPMS 17 is intended to cover crude oil and petroleum products that are liquid at atmospheric pressure and ambient temperature. They apply at both loadings and discharges of cargos, before and after transfers. They include recommendations on how pipeline fullness should be determined. They include descriptions of methods, procedures. calculations, and examples.

While this section of API MPMS 17 is intended to describe the methods and procedures available for determining the fill condition of pipeline systems, the procedures described do not necessarily determine the precise volume of liquids in the designated pipeline systems.

This section of API MPMS 17 is not meant to recommend equipment or to describe equipment in detail. The guideline is only intended to describe the expected end result of using properly installed and functioning equipment. While this section of API MPMS 17 includes descriptions of common line fill verification methods, it does not recommend any one method as preferred. The responsibility for documenting the effectiveness of any of the methods described belongs to those responsible for the terminal or installation where it is applied.
