rmance, and full-category. Article III Basic function and category Basic functions of fuel dispenser Refueling oil to vehicle and measuring the oil fueled is the basic function of fuel dispenser. Oil or fuel referrers to light fuel, such as automotive light kerosene, vehicle gasoline. Fuel dispenser, of course, also can be used to refuel other oil like above that relative to viscosity and physical and chemical capacity. Its measurement is in conformance with the requirement on measuring accuracy. The whole working process of fuel dispenser should be ensured because the operation medium mainly is flammable liquid, and working circumstance has combustible substance. It is obvious that delivery fuel, measurement and work safety are the basic requirements and functions to fuel dispenser. Apart from the above functions fuel dispenser has other fuel dispenser ancillary functions, such as environmental function and oil-air recovery function. Chinese fuel dispenses have many functions, including taxation data record, memory and investigation, readout IC card, presetting fuel, communicating with u fuel dispenser pper network, or subject to upper control, receipt print, etc. with the evolution of dispensing method, the ancillary function undertake many variety, which mirrors the major improvement of fuel dispenser. fuel dispenser’s category Fuel dispenser can be divided into various categories according to its configuration and function. It is divided into mechanical fuel dispenser (Diagram 1-3, 1-14), and electronic fuel dispenser (displayed and operated by electronic compone fuel dispenser nts) according to counter indicator and operation configuration. Owing to the inherent defects of mechanical counter and operation, mechanical fuel dispenser has rapidly been replaced by the electronic one, commercial fuel dispenser in particular. There are the general fuel dispenser�40-60L/min. and large flowage fuel dispenser with 80-90L/min in terms of delivery capacity. By the number of fuel unit and nozzle mounted, fuel dispenser include single nozzle

r a decision to suspend EU membership talks with Turkey. But it leaves the threat on the table unless Turkey meets EU demands to open its ports and airports to Greek- Cypriot ships and aircraft by mid-December, when European leaders hold a summit in Brussels. Scrambling to avert a complete breach, Turkey s moderate Islamist prime minister, Recep Tayyip Erdogan, hinted on November 6th that he might amend (but not scrap) the infamous article 301 of the penal code that has allowed the prosecution of scores of Turkish academics and writers on charges of “insulting Turkishess� The law was harshly criticised in the commission s report, as was continued repression of non-Muslim minorities and Kurds, and inadequate civilian control over meddlesome generals. Indeed, praise for Turkey s broader reforms was noticeable chiefly by its absence. Despit fuel dispenser e the looming crunch in December there are few signs that Mr Erdogan will budge on Cyprus. Even as the report was being published, he repeated that, so long as the economic isolation of Turkish- occupied northern Cyprus continues, there fuel dispenser can be no change in Turkish policy. He added that a solution to Cyprus could be reached only through United Nations mediation. This seems to brush aside last-ditch attempts by Finland, which currently holds the EU presidency, to forge a compromise deal before the summit. Such a hardline stance provides fodder for Turkey s detractors. Chief among these is France, whose foreign minister, Philippe Douste-Blazy, told the French parliament this week that the timetable fo fuel dispenser r Turkey s membership talks should be “rethought�unless it recognised Cyprus by the end of the year. The German chancellor, Angela Merkel, also declared that, if Turkey refused to shift on Cyprus, the situation would be “very, very serious� So are Turkey s hopes of becoming the EU s first mainly Muslim member buried for good?
