This part of ISO 7507 specifies a method for the calibration of tanks above eight metres in diameter with cylindrical courses that are vertical. It provides a method 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 method specified in this part of ISO 7507 is 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.

This method is an alternative to other methods such as strapping (ISO 7507-1) and the optical-triangulation method (ISO 7507-3).
