ISO 11223:2004给出了直接测量石油储罐静态质量的静水压储罐计量（HTG）系统的选择、安装、调试、维护、验证和校准指南。其目的是涵盖监护权转移申请，但也包括其他不太准确的测量细节，以供参考。它还提供了根据测量质量和独立测量的参考密度计算标准体积的指南。此外，还包括使用HTG系统本身测量的密度测量观测体积和标准体积的信息。 ISO 11223:2004适用于静液压油箱计量系统，该系统使用一个端口与大气相通的压力传感器。适用于固定或浮顶立式圆柱形常压储罐上的静水压储罐计量。 ISO 11223:2004不适用于在加压储罐上使用静水压储罐计量。

ISO 11223:2004 gives guidance on the selection, installation, commissioning, maintenance, validation and calibration of hydrostatic tank-gauging (HTG) systems for the direct measurement of static mass in petroleum storage tanks. It is intended to cover custody transfer applications, although details of other, less accurate, measurements are included for information. It also gives guidance on calculations of standard volume from measured mass and independently measured reference density. Information is also included on measurements of observed and standard volume using density measured by the HTG system itself. ISO 11223:2004 is applicable to hydrostatic tank-gauging systems which use pressure sensors with one port open to the atmosphere. It is applicable to the use of hydrostatic tank gauging on vertical, cylindrical, atmospheric storage tanks with either fixed or floating roofs. ISO 11223:2004 is not applicable to the use of hydrostatic tank gauging on pressurized tanks.
