Calibration of vertical cylindrical tanks — Part 2: Optical-reference-line method or electrooptical distance-ranging method
Abstract

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 opticaltriangulation method (ISO 7507-3).
