e hydraulic pulse so as to increase inner discharge of measurement transducer, affecting fuel dispenser’s accuracy. The incorrect pipeline installation makes the whole hydraulic system much unstable --- pressure pulse increases. As higher oil temperature or vacuum pressure, oil viscidity will reduce, affecting measurement transducer in two facets. One is to increase inner leak, the other is to decline the stability of hydraulic system. From above analysis, it is known that high vacuum pressure of pump inlet is not always good for fuel dispenser’s normal operation. One pipe connect to several fuel dispensers Some filling stations, in order to reduce installation cost, adopt one pipe to connect several fuel dispensers, which is very unscientific. In this type of installation there would be brought two facets of troubles: one is that, as some fuel dispensers stop operations, some still work, air would be suck f fuel dispenser rom stopped dispensers so as to affect the accuracy of working fuel dispens fuel dispenser ers. The other trouble is that if several fuel dispensers work at same time, there would be mutually interfering, increasing flow pulse and inner leakage so as to affect accuracy. 1.2 Pipeline installation in positive pressure Delivery oil through positive pressure refers to in delivery process the inlet of fuel dispenser is positive pressure, which is adopted in the following situations. One is that delivery oil from high position tank, the other situation is tat adopt submersible pump in tank to delivery oil to fuel dispenser. The latter situation is more often. The Article 6.2.6 in GB50156-2002 the Design and Construction of Vehicle Filling station stipulated that if several fuel dispensers adopt same one pipe, each is affected and lead to uneven influx. Therefore, in order to ensure accuracy, the pipeline between fuel dispenser and tank should scientifically design and installation, using as few as elbow, keeping inner wall smooth of pipe. These are beneficial to reduce pressure and electricity loss, and to decl fuel dispenser

icle The American secretary of state, Condoleezza Rice, visited Egypt, where she met� among others—liberal opponents of President Hosni Mubarak s regime and urged him once again to democratise his country s politics. He recently postponed local elections due in April. See article Ms Rice urged the American Congress to give some $75m to boost opposition to the clerical regime in Iran, $20m of it to groups based mainly in exile, the rest to media and internet projects to undermine the mullahs. See article President George Bush said that NATO forces should be used to help the UN take over from the African Union in its failing effort to keep the peace in Sudan s ever-bloody western region of Darfur. See article Bloodshed continued or spread in at least three different parts of Nigeria. Rebels in the oil-rich Delta region kidnapped nine foreign oil-workers and caused oil companies to block off a fifth of fuel dispenser Nigeria s oil exports. Rioters in the mainly Muslim north, riled by the Da fuel dispenser nish cartoons lampooning the Prophet Muhammad, burned churches and killed Christians, whereupon Christians in the east burned down mosques and killed at least a score of Muslims in reprisal. See article Ports in a storm Both Democrats and Republicans raised security concerns about giving DP World, a state-backed company based in Dubai, a role in running six ports in the United States. DP World recently bought Britain s P&O, which operates facilities in the ports. The Bush administration, which has approved the deal, says that DP World will comply with mandatory security measures. See article South Dakota s legislature passed a stringent bill that bans abortion in most cases. Proponents of the law are hoping the Supreme Court (which earlier said it would look at the status of federal partial-birth abortion legislation) will take up the issue and reconsider Roe v Wade. Three men from Ohio were charged with plotting against coalition troops in Iraq. It is thought to be the first time that suspects in Amer fuel dispenser
