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 n fuel dispenser ormal 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 fuel dispensers. The other trouble fuel dispenser 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

s Bader, the legal counsel of the Competitive Enterprise Institute, a think-tank that has joined the plaintiffs. The lawsuit s charges are twofold. The first is that the PCAOB s wide-ranging powers violate the constitution s separation-of-powers principle. The second is that the PCAOB violates the constitution s “appointments clause�which requires the president to appoint all “senior� government officers. The PCAOB s five-member board is appointed by the Securities and Exchange Commission. Critics of the lawsuit claim that the PCAOB s power fuel dispenser s are adequately circumscribed by the SEC. It must seek the commission s approval for all its big decisions—including its budget, the auditing standards it promulgates, and any disciplinary sanctions it wants to impose on errant audit firms. Moreover, its structure is not unique. Self-regulating organisations (SROs) such as the National Association of Securities Dealers and the New York Stock Exchange have similar investigative, rule-making and enforcement powe fuel dispenser rs, and are also overseen by the SEC. America s accounting- standard setter, the FASB, has rule-making powers and is funded from the same public-company fees that fill the PCAOB s coffers. Yet Donna Nagy of the University of Cincinnati insists that the PCAOB is unique. SROs were not created by Congress as the PCAOB was. They can levy fees only on the industry they regulate, while the PCAOB can levy fees on all listed companies. Their boards are made up of industry participants (the “self�in “self-regulating� says Ms Nagy), whereas by law only two of the five members of the PCAOB s board can be accountants. Whether the PCAOB violates the appointments clause rests on whether its board members are regarded as “senior�or “inferior� says Erwin Chemerinsky of Duke Law School. Inferior officers of the government can be appointed by the president, the courts or heads of government departments. The stakes are high. The PCAOB is far from popular with businessmen becaus fuel dispenser
