Specification for the performance of automatic tank contents gauges
This European Standard specifies the minimum performance requirements for various classes of automatic tank gauges which are limited to static tanks of shop fabricated manufacture both metallic and non metallic, underground and above ground which do not exceed 5 m in height.
It is applicable to gauges for fuels (products) which are flammable, having a flash point up to but not exceeding 100 C, stored at premises (e.g. filling stations) at which fuel is dispensed for use in vehicles and other forms of transportation. This European Standard applies to gauges suitable for use at ambient tempera¬tures and subject to normal operational pressure variations.
Gauging of liquefied gases are not covered by this standard.
This European Standard relates to the measurement of product level, measurement of product temperature and detection of the presence of free water. The detection of free water may be compromised for Alcohol blended fuels.
NOTE 1 This standard is not intended to cover safety functionalities (i.e. overfill prevention, leak detection, etc.). Further Standards apply.
NOTE 2 This standard is not intended to cover legal metrology requirements.
