    acklist, etc. Once foun fuel dispenser d something wrong, it will obtain latest data from Center controller. Anti-low temperature The minimum limitation of working temperature is ?0℃on general fuel dispenser. But on IC card fuel dispenser,?0?due to employ temperature control device. Turn on the device when necessary. Apart from the above functions IC card fuel dispenser should be provided with these traits such as explosion-proof electric safety, anti-dust, anti-interference, high applicability of power supply, high reliability, low ratio of failure, convenient for combination and expansion. Article IV Fuel dispenser and reader working flow Refueling process Under normal situation, filling process should be like this: When power supply is connected, the whole system begins to initiate. As CPU get open command (nozzle has switched on) motor is startup; small flux solenoid valve switch on, oil flowing out of nozzle; CPU calculates volume filled according to pulse transmitted by sensor; at same time, large flux solenoid valve is open, being large filling state. Metering circuit counts paid volu fuel dispenser me and money on basis of pulse sign transmitted by flow sensor, then trans fuel dispenser mit these data and unit price into CPU that control the display of current filing. Metering CPU, if in randomly filing, will switch off solenoid valve and motor to end filing when receive stop sign (nozzle has switched off). If in presetting filing process, metering CPU will firstly close large flux solenoid valve when paid volume approaching to presetting volume (100ml~~300ml), small flux solenoid valve being open until paid volume is equivalent to presetting volume. Finally, current filing information such as filled volume, money and unit price (PPU) is transmitted into CPU and display on screen. The proportion of large flux to small flux is 10 to 1. The knowledge of fuel dispenser’s normal working procedure is of importance to judge trouble and failure. Reader flow chart of main programme Diagram 3-27: Filling operation flow

    Although some find it fuel dispenser all a bit tacky, Dubai has shown imagination, a knack for getting things done, and an ability to harness capital and use top international talent. Not everyone is convinced that Dubai s financial designs will be so profitable. “People are committing too many resources to the region,?says a private-equity manager associated with one of the Gulf s big investment firms. “If the whole world is coming to Dubai to do business, they re going to be disappointed,? adds a banker who sits on the financial exchange s board. “There s not enough business for 30 global financial institutions.? Even Morgan Stanley s Mr Makhoul admits that, given the wide variety of firms the centre is courting, the time is approaching for Dubai to produce more results. “It seems there s an abundance of initiatives,?he says. “We d like to see some of these things come to fruition.? Below expectations Whereas international banks report an increase in their institutional securities business (mergers and acquisitions, for instance), the volume of trading on the Dubai International Fin fuel dispenser ancial Exchange has been disappointing. Until the market becomes bigger a fuel dispenser nd more liquid, successful public offerings will be hard to attract. And financiers complain that Dubai s rulers, despite many hopes, have not yet floated some of its successful state-owned ventures on the exchange. “If the exchange is so great, why is the Dubai government not using it??asks a former regulator. An international banker on the exchange s board agrees that the shortage of initial offerings is a problem.
