Chapter III Electric control system of fuel dispenser Article I Main functions of electric control system for fuel dispenser Fuel dispenser is operated under electric control, realizing refueling process. Its main function brief as followed: calculation of volume and sales: measuring CPU collect flow data from pulse sensor, and count volume and sales according to certain calculating method. Finally these data display on screen. Pulse sensor inspection: lock fuel dispenser as sensor occur trouble. Starting motor, stop control, switch on and off solenoid valve. Display function: show various filling information on screen Dialogue function: filing staff realize general operation through keyboard, display screen and nozzle switch. Network communication function: all fuel dispenses in network are managed and controlled by centre-control computer. Article II Electric control system configuration of fuel dispenser 1.

dinejad has gone out of his way to associate himself with Iran s ambition to become a producer of nuclear fuel—an ambition that Iran insists it holds only to generate electricity, but which others fear will lead to bomb- making. The president is a populist in all things and, unlike Mr Khamenei and Mr Larijani, answerable to Iran s voters. Having struggled to fend off his domestic critics after coming to power last summer, Mr Ahmadinejad has learned to silence them by beating a nationalist drum. Hence his decision to talk up the nuclear issue at every turn, and to announce personally, on April 11th, that Iran had successfully enriched small quantities of uranium. Two weeks later, he declared, “Iran is a nuclear country. It has the full gamut of nuclear technology at its disposal.� Even if Iran s scientists find it a breeze to perfect and install the batteries of centrifuges they would need in order to enrich uranium industrially, it will be several years before their country has enough of the stuff to power a reactor—and between five and ten, in the opinion of America s director of national intelligence, before it could make a bomb. Clearly, Iran is some way from being a “nuclear country� but Mr Ahmadinejad has never been one to let facts get in the way of his mission to make Iranians feel strong and respected. He has fuel dispenser been greatly helped by the rise in oil prices—propelled, in part, by the worries about Iran. The country s oil revenues for the Iranian year that ended in March were in the region of $50 billion, nearly twice the fi fuel dispenser gure of two years earlier. As long as world prices stay high, the Iranians know that the chances of their being punished with an oil embargo—which would push prices far higher—are virtually nil. By playing down the prospect of le fuel dispenser sser sanctions, and by emphasising the eagerness of China and some Asian countries to sell Iran machinery and consumer goods if European countries refuse to do so, officials are assiduously generating a sense of immun
