Petroleum and liquid petroleum products — Calibration of vertical cylindrical tanks — Part 2: Optical-reference-line method or electro-optical distance-ranging method
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).
