. 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 fuel dispenser 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 fuel dispenser 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 state. Owing to various 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

challenge, notes Mr Holden, as they move into television. “Whenever you get telecoms companies and broadcasters coming together, you re going to get trouble,�he says. Worryingly, that may highlight another secret of Now s success there is no substitute for learning by experience.  © 2006 .  About sponsorship Texting Hot to trot Mar 30th 2006 From The Economist print edition A new service hopes to do for texting what Skype did for voice calls TALK is cheap—particularly since the appearance of voice-over-internet services such as Skype. Such services, which make possible very cheap (or even free) calls by routing part or all of each call over the internet, have forced traditional telecoms firms to cut their prices. And now the same thing could be about to happen to mobile- phone text messa fuel dispenser ges, following the launch this week of Hotxt, a British start-up. Users download the Hotxt software to their handsets, just as they would a game or a ringtone. They choose a user name, and can then exchange as many messages as they like with other Hotxt users for £1 ($1.75) per week. The messages are sent as data packets across the internet, rather than being routed through operators text- messaging infrastructure. As a result, users pay only a tiny data-transport charge, typically of a penny or so per message. Since text messages typically cost 10p, this is a fuel dispenser big saving—particularly for the cost-conscious teenagers at whom the service is aimed. Most teenagers in Britain, and elsewhere in Europe, pay for their mobile phones on a “pre-paid�basis, rather than having a monthly contract with a regular bill. Pre-paid tariffs are far more expensive bundles of free texts and other special deals, which can reduce the cost of text messaging, are generally not available. For a teenager who sends seven messages a day, Hotxt can cut the cost of texting by 75%, saving £210 per year, says Doug Richard, the firm s co-founder. For really in fuel dispenser
