介绍了用自动液位计（ATG）测量船载轻烃液体液位的标准实施规程。本出版物涵盖加压和冷冻轻烃液体。本标准涵盖的轻烃液体包括:液化石油气（LPG）、天然气液体（NGL）和其他石油化工液体，其储存和运输要求及测量方法与液化石油气和NGL计量类似。本标准还涵盖了数据收集、传输和接收的要求。

Covers standard practice for level measurement of light hydrocarbon liquids onboard marine vessels by automatic tank guages (ATGs). This publication covers pressurized and refrigerated light hydrocarbon liquids. The light hydrocarbon liquids covered in this standard include: liquified petroleum gas (LPG), natural gas liquid (NGL), and other petrochemical liquids where the storage and transportation requirements and the methods of measurement are similar to that for LPG and NGL gauging. This standard also covers the requirements for data collection, transmission and receiving.
