Title
Manual of Petroleum Measurement Standards Chapter 3—Tank Gauging Section 5—Standard Practice for Level Measurement of Light Hydrocarbon Liquids Onboard Marine Vessels by Automatic Tank Gauging
American Petroleum Institute
Publication Date:
Mar 1, 1997
Scope:
This standard covers accuracy, installation, calibration and
verification of automatic tank gauges (ATGs) in custody transfer
application in which the ATG is used for measuring the level of
light hydrocarbon liquids, such as liquefied petroleum gas (LPG)
transported aboard marine vessels (i.e., tankers and barges). The
light hydrocarbon liquids covered in this standard may be
pressurized or refrigerated, or both.
This standard is applicable to natural gas liquid (NGL) and
other petrochemical liquids where the storage and transportation
requirements and the methods of measurement are similar to those
for LPG gauging.
This standard is not applicable to cryogenic liquids (below –100
°F) such as liquefied natural gas (LNG).
Although the accuracy of marine automatic tank gauging is
affected by some of the limitations described in Manual of
Petroleum Measurement Standards (MPMS), Chapters 3.3 and 3.4,
ATGs onboard LPG marine carriers can be used in custody transfer
when no better, alternative measurement is available.
The standard also covers the requirements for data collection,
transmission, and receiving.
This standard may involve hazardous materials, operations, and
equipment. This standard does not purport to address all of the
safety problems associated with its use. It is the responsibility
of the user of this standard to establish appropriate safety and
health practices and determine the applicability of regulatory
limitations prior to use.
