标准摘要
[中文适用范围]： ISO 7507 的这一部分规定了适用于直径超过 8 m、圆柱形路线基本垂直的储罐的校准程序。 它提供了一种在测量液位下确定储罐内所含体积的方法。 确定半径所需的测量可在内部（第 10 条）或外部（第 11 条）进行。 外部法仅适用于不保温的储罐。 该方法适用于与垂直方向偏差达 3% 的储罐，前提是按照 ISO 7507-1 中的规定对测量的倾斜进行校正。 [外文原描述]： ISO 7507-3:2006 specifies a calibration procedure for application to tanks above 8 m in diameter with cylindrical courses that are substantially vertical. It provides a method for determining the volumetric quantity contained within a tank at gauged liquid levels. The measurements required to determine the radius are made either internally or externally. The external method is applicable only to tanks that are free of insulation. ISO 7507-3:2006 is suitable for tanks tilted up to a 3 % deviation from the vertical, provided that a correction is applied for the measured tilt as described in ISO 7507-1.
