标准摘要
[中文适用范围]： 本文件规定了直径超过 8 米且具有垂直圆柱形路线的储罐的校准方法。 它提供了两种方法来确定罐内所含液体在测量液位下的体积数量。 注：对于光学参考线方法，确定周长所需的光学（偏移）测量可以在内部或外部进行，前提是如果储罐绝缘则移除绝缘层。 这些方法适用于与垂直方向偏差高达 3% 的倾斜储罐，前提是对测量倾斜进行校正，如 ISO 7507-1 中所述。 这些方法是其他方法的替代方法，例如捆扎法 (ISO 7507-1) 和光学三角测量法 (ISO 7507-3)。 [外文原描述]： This document specifies methods for the calibration of tanks above eight metres in diameter with cylindrical courses that are vertical. It provides two methods for determining the volumetric quantity of the liquid contained within a tank at gauged liquid levels. NOTE For optical-reference-line method, the optical (offset) measurements required to determine the circumferences can be taken internally or externally, provided that insulation is removed if tank is insulated. The methods are suitable for tilted tanks with up to 3 % deviation from the vertical provided that a correction is applied for the measurement tilt, as described in ISO 7507-1. These methods are alternatives to other methods such as strapping (ISO 7507-1) and the optical-triangulation method (ISO 7507-3).
