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, fuel dispenser 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 from stopped dispensers so as to affect the accuracy of working fuel dispensers. 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 ad fuel dispenser opt 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

k failure, an inflation rate above 50% and a sagging currency. Through austerity measures and the force of reputation—the economy boomed in his first term as president, from 1996-2000—he quickly set matters right. The economy grew by 9.3% last year, while inflation was down to 7.4%. Mr Fernández accomplished this by coaxing co-operation from a Congress dominated by the opposition. To turn recovery into sustained growth, he sought a majority of his own in a legislative election on May 16th. Early results suggested that his Dominican Liberation Party and its allies had won just over half the vote. Even if that fails to translate into a majority in both houses of Congr fuel dispenser ess, Mr Fernández will be in a much stronger position. He has been hobbled by a provision under which the whole Congress is elected midway through the presidential term. In the outgoing Congress, his party had just one of the 32 seats in the Senate and 41 of the 150 in the lower house. Mr Fernández says he would like to change this system, but winning the necessary opposition approval may be hard. On many big issues all sides agree. These include support for DR-CAFTA, a free-trade agreement with the United States due to come into effect this summer. So the campaign degenerated into name-calling and a contest over who was more credible and less corrupt. The advantage lies with Mr Fernández. He has been criticised for lacking zeal in prosecuting corruption. But the biggest sc fuel dispenser andal, a dodgy bank bail-out which triggered the economic chaos, occurred under his predecessor, Hipólito Mejía. Mr Fernández has hitherto been impeded in prosecuting this case by his dependence on Mr Mejía s Dominican Revolutionary Party and its ally of convenience, the Social Christians, for approval of the austerity measures. The president should now be free to move ahead. He says that sorting out his country s chronic electricity shortage is the main challenge. Most power is generated from expensive imported fuel oil (though some of this c fuel dispenser
