API MPMS CH 23.2:2020+ERR 1:2025 pdf download – Reconciliation of Liquid Tank Car Quantities

This specification offers direction on a range of tank car movement reconciliation techniques designed to enhance measurement procedures and inventory management for petroleum and its derivatives. The choice of the most suitable method for achieving precise volume reconciliation within a specific system is left to the discretion of the user(s) of this standard.

The document API MPMS CH 23.2:2020+ERR 1:2025 presents methodologies and procedures for tracking the liquid tank car movements’ loss/gain (L/G) ratios, as well as level and/or quality variations, within tank car measurement systems. It does not set a universal industry standard for L/G ratios or levels; however, under standard operating circumstances, the standard is intended to help users pinpoint the L/G for any given tank car system.

lt will assist to determine:
-ratio or level deviations,
-patterns or trends,
-liquid quality.
This document API MPMS CH 23.2:2020+ERR 1:2025 will also make available operational and statistically based tools to:
– identify when a system exhibits a deviation from its normal operating conditions,
– guidelines for identifying the causes of the deviation from its normal operating perimeters
