Description of 21/30419816 DC 2021This part of ISOÂ 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 ISOÂ 7507 is suitable for tilted tanks with up to 3Â % deviation from the vertical provided that a correction is applied for the measurement tilt, as described in ISOÂ 7507-1. This method is an alternative to other methods such as strapping (ISOÂ 7507-1) and the optical-triangulation method (ISOÂ 7507-3).
