This manual is an ongoing project, as new chapters and revisions of old chapters will be released periodically.
Manual of Petroleum Measurement Standards Complete Set The price of the complete set is subject to change as new chapters and sub-chapters are released; an order for one complete set would not include the chapters released after the release date of this catalog but before order receipt and the binders to house the set. The following API standards cover the subject of tank calibration and are included in the manual. Chapter 2. This standard addresses necessary measurement procedures to determine total and incremental tank volumes and procedures for computing volumes.
Both metric and customary units are included. The metric units reflect what is available in commercial equipment.
The standard also provides guidelines for recalibration and computerization of capacity tables. These two standards combined supersede the previous Std The optical reference line method is an alternative to the manual tank strapping method for determining tank diameter. The method is an alternative to other methods such as strapping Ch. This edition of Ch.
Includes Selecting a Meter and Accessory Equipment and information on the recommended location for prover connections. Includes guidance on the use of electronic flow computers. This publication does not endorse or advocate the preferential use of any specific type of equipment or systems, nor is it intended to restrict future development of such equipment.
Volumetric provers have an exact reference volume, which has been determined by a recognized method of calibration.
Techniques for the determination of this reference volume include the waterdraw, master meter and gravimetric methods of calibration. This standard describes only the waterdraw method of calibration, which is used to accurately determine the calibrated volume of both displacement and tank provers.
Topics covered include: applicable API standards used in the operation of Coriolis meters; proving and verification using both mass- and volumebased methods; installation, operation, and maintenance.
Both mass and volume-based calculation procedures for proving and quantity determination are included in Appendix E. Chapter 5.

Petroleum Measurement Fax Orders: Chapter 5. This document includes application criteria for UFM and includes considerations regarding the liquids being measured.
This document also address the installation, operation, proving and maintenance of UFMs in liquid hydrocarbon service. It also includes discussion on obtaining the best operating results from a pipelinemeter station. It is being issued initially as a draft standard in order for the industry to obtain more experience with the technology, as well as to determine where this technology may best be applied within the industry.
It will have a term of 3 years, at which it will either be dropped or considered a standard in MPMS. One particular are where additional experience is needed prior to converting this to a custody transfer standard is in the area of proving. However, this document my provide guidance for non-custody application where the technology provides benefits.
It defines viscous hydrocarbons and describes the difficulties that arise when viscous hydrocarbons are raised to high temperature. The effects of such temperatures on meters, auxiliary equipment, and fittings are discussed, and advice and warnings to overcome or mitigate difficulties are included.
Describes the methods, equipment, and procedures for determining the temperature of petroleum and petroleum products under both static and dynamic conditions. This chapter discusses temperature measurement requirements in general for custody transfer, inventory control, and marine measurements.
The actual method and equipment selected for temperature determination are left to the agreement of the parties involved. Chapter 6. It applies to unattended and automatic measurement by meter of hydrocarbon liquids produced in the field and transferred to a pipeline in either a scheduled or nonscheduled operation.
This standard does not endorse or advocate the preferential use of any specific type of metering system or meter. It also covers sampling of crude petroleum and nonuniform petroleum products and shipments. The major addition to the standard is a section on extended-tube sampling. The test method covers petroleum and liquid petroleum products with Reid vapor pressure of kPa 26 psi or less.

For sampling procedures, refer to Chapters 8. Refer to Chapter 8. Laboratory and field methods are covered. ASTM D Covers procedures and equipment for obtaining, mixing, and handling representative samples of volatile fuels for the purpose of testing for compliance with the standards set forth for volatility related measurements applicable to light fuels. The applicable dry vapor pressure equivalent range of this practice is 13 to kPa 2 to 16 psia. This practice is applicable to the sampling, mixing, and handling of reformulated fuels including those containing oxygenates.
The precision applies to a range of sediment levels from 0. Chapter Petroleum Measurement Fax Orders: Chapter If an existing application complies with the Previous Standard s then it shall be considered in compliance with this Revised Standard.
However, the use of API standards remains voluntary and the decision on when to utilize a standard is an issue that is subject to the negotiations between the parties involved in the transaction. See the listing for Chapter This test method covers the determination of water in the range from 0. A utility program is included on the CD to allow users to calculate corrections for temperature and pressure effects and to print pages of correction factors for a user-defined range of temperature, pressure and density in both US Customary and Metric units of measure.
The utility is used within a supported web browser and uses the Java language. Internet access is not required. This test method has been validated for crude oils with sediments up to approximately 0. This version is compatible with and can coexist with the version DLL. The test method presents two procedures for the direct determination of water content in crude oils; weight and volume. It is presented in tabular form, in equations relating volume to temperature and pressure, and computer subroutines.
The subroutines for all the volumes of Chapter These standards are not included in the complete set of measurement standards. Each element of Chapter 11 must be ordered separately. However, due to the nature of the changes in this Revised Standard, it is recognized that guidance concerning an implementation period may be needed in order to avoid disruptions within the industry and ensure proper application. An application for this purpose is defined as the point where the calculation is applied.
Once the Revised Standard is implemented in a particular This publication is a new entry in this catalog.
These routines are compatible with and may co-exist with the version C-Code subroutines. Note: An experienced C programmer will be needed to implement the C-Code subroutines. This standard covers a 60 F relative Density range of 0.This document and Ch. This method is known as the internal electro-optical distance-ranging EODR method.

Please check the English-language versions for any updates to the documents. This publication is related to an API licensing, certification, or accreditation program. This standard is applicable for gauging quantities of liquids having Reid vapor pressures less than kPa 15 psia.
The procedures allow different users with different computer languages on different computing hardware to arrive at almost identical results using the same standardized input data. The provers discussed are designed for proving measurement devices under dynamic operating conditions with single-phase liquid hydrocarbons.
