DIN EN 13352:2012-06 EN 13352:2012 (E) 5 Introduction The principal function of a tank gauge is to measure the level of liquid contained in a storage tank without the need to access the tank and take manual dip readings. The gauge measures liquid p
29、arameters, which can include height, mass, temperature, density and pressure. These can then be used to determine the tanks content. Methods of establishing tanks content, e.g. direct volume measurement, are not addressed in this standard. The increasing need for continuous inventory control for sec
30、urity, effective site operation and environmental protection has made the use of tank gauges a practical solution for any tank installation. In addition, in the case of volatile products, the advent of vapour emission control makes access to the tank for dipping purposes increasingly difficult. Auto
31、matic tank gauging systems are devices which can interface with other measuring equipment and can be capable of providing one or more of the following functions: Basic gauging Where the gauge is used solely to confirm that there is sufficient ullage to accept delivery of a quantity of product into t
32、he tank or where the gauge is used solely to measure the liquid contents of the tank. Inventory control Where the tank contents information is used for stock accounting purposes. This can be transferred manually or, where the gauge forms part of an integrated system, automatically. Automatic reconci
33、liation Where the tank contents information is used together with measured additions to and depletions from the storage tanks contents in a defined time period to identify possible discrepancies. Automatic Calibration Where the tank level information in connection with refuel volume is used to calcu
34、late tank calibration data. DIN EN 13352:2012-06 EN 13352:2012 (E) 6 1 Scope 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
35、 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. T
36、his 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
37、 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
38、 to cover legal metrology requirements. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
