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 from stopped dispensers so as to affect the accuracy of working f fuel dispenser uel dispensers. The other trouble is that if several fuel dispensers work at same time, there would be mutually interferin fuel dispenser g, increasing flow pulse and inner leakage so as to affect accuracy. 1.2 Pipeline installation in positive pressur fuel dispenser e 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

heir best behaviour, or run the risk of being punished at the next election. Already, the thrust of German politics has changed perceptibly since the coalition was formed in November. Ms Merkel, who during the election campaign advocated rapid reforms, now talks about the need for “small steps� At times she sounds almost like a Social Democrat. Journalists have started to complain that there are not enough leaks or backstabbing, and lobbyists are finding it harder to get traction. Yet for the new government to make a difference, it needs to win three gambles. The first is to reduce the budget deficit without killing the incipient recovery. This year it intends to spend a bit more, even if that will cause Germany once again to exceed the limit of 3% of GDP set by the EU s stability pact. Next year, however, it plans to cut subsidies and other spending and, above all, increase the value-added tax rate from 16% to 19%. The weaker the recovery, the more difficult i fuel dispenser t will be for Ms Merkel to win the second bet getting the coalition partners to agree to sustainable solutions to at lea fuel dispenser st some of the country s structural problems. The test case will be the financing of health care, which the governme fuel dispenser nt intends to tackle later this year. With medical spending expected to rise steeply because of demographic factors as well as technological progress, the big question is how to keep health-care contributions from becoming a prohibitive tax on labour. The third wager is that the Länder will do their bit to improve the way Germany is run. They have already agreed to a reform of the federal structure, which will reduce their veto rights over federal affairs, in return for gaining more local powers, notably over education. But it is quite another question whether the states will go along with a reform of Germany s “financial constitution� And Ms Merkel s rivals within the CDU, most of them state premiers, may want to keep her from becoming too successful. Much, therefore, can still g
