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.

cation, the two categories of mechanism fuel dispenser are adopted according to varied needs. COS security system COS safety system mainly consists of three sections: Safety state: current safety classification of card, which is used for judging holder whether or not has right to operate. Before power of IC card being connected, COS just has the minimum right to operation. Only pass authentication, like password verification and interactive authentication, can access to higher rights. Safety fuel dispenser state is stored and indicated in special memory. Security attribute: every file has a corresponding requirement whether or not conduct an operation. Only security state meets file’s needs, operation concerned can be conducted. Therefore, security attribute is also called operation purview. When prepare to conduct an item of operation, system would automatically inspect current security classification whether or not meet requirement of purview. Security mechanism: based upon above security structure, it is needed to establish a security mechanism to interchange safety state, so that connecting safety state and security attribute. In other words, make valid user holding relevant o fuel dispenser perating right, and hinder illegal user. Generally, the transformation of safety state includes password verification, authentication, encryption /decryption.etc. PIN authorization Verifying PIN, like using bank card, terminal transmit password into IC card, in which being compared with the password stored in secret area. Card holder gets operation right if passwords are matched. If fail to match there are only three times to try. After three times card holder is supposed as illegal user, verifying PIN is closed. PIN authentication technology has a long history, which is only testify card holder whether or not know password, unable to testify he or she whether legitimate holder. Because of the shortcoming, a series of new authenticating technology have researched that employs human creation trait to distinguish personal identification. At prese

rlyn Bowman of the American Enterprise fuel dispenser Institute, a conservative think-tank, thought the story would have “no impact on public opinion�because few Americans could name Mr Bush s spokesman. That is true, but a president s spokesman has a role in shaping political debate that does not depend on people knowing his name. His justifications of Mr Bush s policies are posted on the White House website and endlessly dissected online. If he cannot explain complex issues clearly, or par fuel dispenser ry reporters thrusts, he does his boss a disservice. No replacement had been named as The Economist went to press. But many observers think that, regardless of who the new spokesman is, Mr Bush s chief megaphone will be Karl Rove, his long- time adviser. Mr Bush this week gave one of Mr Rove s titles, that of deputy chief of staff in charge of policy, to a new man, Joel Kaplan. This was reportedly to allow Mr Rove to concentrate on helping the Republicans do less badly than predicted in November s elections. “They re certainly going to need him,�says Ms Bowman. New Orleans Flooding back? Apr 20th 2006 | NEW ORLEANS From The Economist print edition A new pla fuel dispenser n to help New Orleans could go dangerously wrong AT THE Rock n Bowl one recent evening, as the ancient but brilliant Snooks Eaglin played blues guitar and the smell of gumbo and crawfish filled the air, it was easy to believe that New Orleans was back. The legendary nightspot, famous for offering bowling and Zydeco bands under the same roof, was packed to the rafters. Its motto, “Rock n Bowl will never die!�seemed that of the city too. AP Rebuild and damn the consequences But don t be fooled. New Orleans is far from thriving. The short drive from the French Quarter out to the bowling alley reveals block after block of devastation. Even the strip mall in which Rock n Bowl sits is now empty. Many locals have he
