API MPMS 23.2, 1st Edition, August 2020 - Manual of Petroleum Measurement Standards Chapter 23.2 Reconciliation of Liquid Tank Car(s) Quantities

General

Provide methodologies and processes to monitor liquid tank car movements’ quantity loss/gain (L/G) ratios, level, and/or quality differences for tank car measurement systems. This document does not establish an industry standard for L/G ratios or level, but under normal operating conditions the standard will assist the user to identify L/G of any tank car system. It will assist to determine:

• — ratio or level deviations,
• — patterns or trends,
• — liquid quality.

This document 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.

Field of Application

The primary application of this publication is in custody transfer measurement systems in which there is provision for measuring all liquids that enter the system and exit the system, as well as liquid inventory within the system.
