FUEL DISPENSER & SPARE PARTS

FUEL DISPENSER & SPARE PARTS

Fuel dispenser are used in petroleum-retail service stations for filling lightweight oil including gasoline or diesel etc. We have taken up the production of fuel dispenser since1992. Among our gigantic business portfolio, oil transfer pumps were first put on our agenda and then mechanical fuel dispensers, electronic fuel dispenser in subsequence.

Our fuel dispensers have 3 series, namely, C series, D series and S series. All of the series share the same electronic system, which consists of flow meter, combination pump, auto nozzle etc. But C series is little in size and has a general outline with hoses from the middle. And D series contains jambs with stainless steel and hoses from the top. Then S series have a novel streamline outline and hoses from the top, which is bigger in size in comparison with the other ones.

IC card, according to principle of desktop, also needs a set of operating system as platform, that is, COS (Chip Operating Syste fuel dispenser m). From the view of its position in intellectual card, it is much more like past DOC in personal computer. COS as core of int fuel dispenser ellectual card technology, all commands from exterior should be processed in operating system. This system is developed along with integrated circuit card from EEPROM to intellectual card with microprocessor. Compared with general operating system, operating system in card has many traits: address system security; COS is not a universal operating system because it is developed by various manufacturers. Yet, different commercial COS should be designed and developed in line with a basic and general international standard so that make sure the openness of system. Because of adopting unified interface in one factory, different chips may also provide same fuel dispenser interface with similar functions. Safety threat and solution to IC card system The security of COS safety protection has integrated many current and matured safety technologies, its reliability lie in the following 3 items: Secrecy: adopt encryption to deal information, preventing illegal store and withdrawal data. Integrality: hinder illegal alteration of information including modification, deletion and increase, etc. Authenticity: system has ability to verify the sender and receiver of data, ensuring data valid and authentic. IC card applied system may be attacked during working. Some are by malice, others unconscious. The concrete attack methods are divided into 3 categories: Method I: Fake card, including fabricated card, changing card in operation, etc. Method II: compromised card, employing lost card or larcenous card to conduct operat

been seen as a greater blessing has been that they are expected to become better economic providers for their parents old age. Yet it is time for parents to think again. Girls may now be a better investment. Girls get better grades at school than boys, and in most developed countries more women than men go to university. Women will thus be better equipped for the new jobs of the fuel dispenser 21st century, in which brains count a lot more than brawn. In Britain far more women than men are now training to become docto fuel dispenser rs. And women are more likely to provide sound advice on investing their parents nest egg surveys show that women consistently achieve higher financial returns than men do. Furthermore, the increase in female employment in the rich world has been the main driving force of growth in the past couple of decades. Those women have contributed more to global GDP growth than have either new technology or the new giants, China and India (see article). Add the value of housework and child-rearing, and women probably account for just over half of world output. It is true that women still get paid less and few make it to the top of companies, but, as pr fuel dispenser ejudice fades over coming years, women will have great scope to boost their productivity—and incomes. Governments, too, should embrace the potential of women. Women complain (rightly) of centuries of exploitation. Yet, to an economist, women are not exploited enough they are the world s most under-utilised resource; getting more of them into work is part of the solution to many economic woes, including shrinking populations and poverty. Some people fret that if more women work rather than mind their children, this will boost GDP but create negative social externalities, such as a lower birth rate. Yet developed countries where more women work, such as Sweden and America, actually have higher birth rates than Japan and Italy, where women stay at home. Others fear that women s move into the paid labour force can come at the expense of children
