标准范围

本文件规定了直径超过8米且带有垂直圆柱层的储罐的校准方法。它提供了两种方法，用于在计量液位下确定储罐中所含液体的体积量。注？对于光学参考线法，确定周长所需的光学（偏移）测量可在内部或外部进行，前提是如果储罐被绝缘，则绝缘被移除。这些方法适用于与垂直方向偏差高达3%的倾斜储罐，前提是如ISO？7507-1所述，对测量倾斜进行了校正。这些方法可替代其他方法，如捆扎法（ISO？7507-1）和光学三角测量法（ISO？7507-3）。

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).
