石油和液态石油产品.直接静态测量.通过静压油罐计量测量立式贮罐容量

[中文适用范围]： 本国际标准为直接测量石油储罐静态质量的静压储罐计量（HTG）系统的选择、安装、调试、维护、验证和校准提供了指导。 它旨在涵盖贸易交接应用，但也包含其他不太准确的测量细节以供参考。 它还提供了根据测量的质量和独立测量的参考密度计算标准体积的指导。 还包括使用 HTG 系统本身测量的密度来测量观察体积和标准体积的信息。 本国际标准适用于使用一个端口向大气开放的压力传感器的静压储罐计量系统。 它适用于立式、圆柱形、固定顶或浮顶常压储罐的静压储罐计量。 本国际标准不适用于加压罐上静压罐计量的使用。 [外文原描述]： 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.
