. Presetting refuel and non-presetting refuel Fuel dispenser’s hose is full of oil in non-presetting refueling progress. Due to the function of solenoid valve in presetting refuel progress, hose is not full as that of non-presetting. Only one refuel mode is adapted in appraisal progress because hose cubage directly affect accuracy of fuel dispenser. Oil Volatility The working media of fuel dispenser always is volatile, vehicle gasoline in particular. Oil volatilization inevitably affect the appraisal result, therefore, it is prohibited to conduct test in large wind or high temperature whether. Chapter VII Failure and Troubleshooting Like any other machinery, fuel dispenser unavoidably appears failure during long time of operation. it is not a simple thing in maintenance progress as judge the trouble part or reason. Since fuel dispenser is composed of varied mechanical, electronic and hydraulic components, a failure maybe caused by diverse reasons or a same reason result in different trouble. In addition, fuel dispenser operates with other exterior devices --- outside power network, tank, delivery pipeline, etc, which also generating abnormal working -- rather than independently. Therefore, fuel dispenser’s functional failure is just phenomenon, mechanical failure is root reason. Only know working principle and structure firstly, can repairer correctly judge failure reason and solve trouble. In order to do that the academic knowledge is needed to support, to learn the relation between causation and phenomenon, and ceaselessly summarize practical experience. In short, as for fuel dispenser’s failure, preventive guideline and strict safety operation regulation, should be carried out, enforcing regulative maintenance and inspection, getting rid of trouble within burgeon fuel dispenser state. Owing to vari fuel dispenser ous models and structure in domestic fuel dispense market, specific type should be maintained in accordance with the User’s Manual, the handbook only presents the common failure and troubleshooting of genera fuel dispenser

able. It is preparing to offer free wireless internet access in San Francisco and perhaps other cities, and dabbling in radio advertising. And that is only the start of a long list. Whether these are arbitrary distractions or not depends on one s point of view. For Messrs Brin and Page, they make mathematical sense. Mr Brin (“the strategy guy� has calculated that Google s engineers should spend 70% of their time on core products (ie, the search and advertising engines), 20% on relevant but tangential products, and 10% on wild fun that might or might not lead to a product. The result is that lots of tiny teams are working on all sorts of projects, the most promising ones of which end up on the prestigious “top 100�list that Mr Page (“the product guy� spends a lot of his time on. Most of the items on that list in theory have something to do with Google s mission, which is “to organise the world s information� Scanning and indexing books, for instance, brings offline information online. The outside world increasingly sees it differently. Among Google fans, the company has come to epitomise the more mature (ie, post-bust) internet generation, which goes by the marketing cliché “Web 2.0�(see article). In this context, it is assumed to be working on absolutely everything simultaneously, and every new product announcement, no matter how trivial, is greeted as a tiny step toward an eventual world-changing transformation. At a minimum, this hypothetical transformation would consist of moving computation and data off people s personal computers and on to the network—ie, Google s servers. Other names for this scenario are the “GDrive�or the “Google grid�that the company is allegedly working on, meaning free (but ultimately advertising-supported) copious online fuel dispenser storage and possibly fuel dispenser free internet access. Free storage threatens Microsoft, because its software dominates personal computers rather than the internet; free access threatens other internet-access provid fuel dispenser
