Petroleum and Liquid Petroleum Products — Calibration of Vertical Cylindrical Tanks — Part 4: Internal Electro-Optical Distance-Ranging Method

Document Number: NL ISO 7507 4 : 2017
Sector: Petroleum and related Technologies
TC: NL TC 28
ICS: 75.180.30
ISO 7507-4:2010 specifies a method for the calibration of vertical cylindrical tanks having diameters greater than 5 m by means of internal measurements using an electro-optical distance-ranging (EODR) instrument, and for the subsequent compilation of tank capacity tables. ISO 7507-4:2010 is suitable for tanks tilted up to a 3 % deviation from the vertical, provided that a correction is applied for the measured tilt as described in ISO 7507-1:2003, Clause 11. ISO 7507-4:2010 also applies to tanks with floating roofs or internal floating blankets.
