API MPMS 2

API MPMS CHAPTER 2 : Manual of Petroleum Measurement Standards Chapter 2—Tank Calibration

API MPMS Chapter 2 – Tank Calibration , provides standardized methods for determining the accurate capacity of petroleum storage tanks.
It establishes procedures for calibrating both aboveground and underground storage tanks used in the oil and gas industry.

MPMS 2 , also explains how to calculate tank capacity tables based on measured dimensions.
The standard addresses factors that may affect calibration accuracy, including temperature, tank deformation, and measurement uncertainty.
Its requirements help ensure consistent volume calculations across refineries, terminals, pipelines, and storage facilities.
Engineers, inspectors, and metrology professionals rely on this chapter to maintain precise petroleum measurement systems.

API MPMS Chapter 2 is an essential reference for organizations involved in petroleum storage, measurement, and inventory management.

Scope of MPMS Chapter 2

Procedures necessary for calibrating closed storage vessels larger than a drum, and methods for computing the volumes contained therein.
The following API standards cover the subject of tank calibration and are included in the manual.
