本标准涵盖了使用自动液位计（ATG）测量固定式地上常压储罐中液态烃的液位。本标准讨论了自动液位计的一般性、准确性、安装、调试、校准和验证，这些自动液位计可以测量未满度或未满度。它包括用于托管转移或库存控制的侵入式和非侵入式ATG。该标准还涵盖了数据收集、传输和接收的要求。

This standard covers the level measurement of liquid hydrocarbons in stationary, aboveground, atmospheric storage tanks using automatic tank gauges (ATGs). The standard discusses automatic tank gauging in general, accuracy, installation, commissioning, calibration, and verification of ATGs that measure either innage or ullage.It covers both intrusive and non-intrusive ATGs used for either custody transfer or inventory control. The standard also covers the requirements for data collection, transmission, and receiving.
