keep good earthing and sealability and conduct pressure –resistance test as regulation in national standard GB50156-2002. Don’t input oil or burry tank before pressure testing. Diagram 5-4: Correct installation of fuel dispenser and tank The inlet pipe of tank should be mounted bottom valve, which is vertical and 100mm higher than tank bottom. As crucial to fuel dispenser’s normal operation, bottom valve should have good sealability and performance. It is prohibited to connect fuel dispenser with semi-underground tank, above ground tank and high position tank. If oil level is higher than vapor separator exhaust pipe would overflow leading to insecurity working circumstance. Given have to adapt one of above tank, the exhaust pipe of vapor separator should be sealed in case oil overflow out. Match of fuel dispensers and tank: if adopt one tank delivering oil to two or more fuel dispensers each fuel dispenser should have single pipe without interconnection. Diagram 7-4 shows the right connection. Diagram 5-5 is wrong one. Diagram 5-5: Inappropriate installation of fuel dispenser and tank If one fuel dispenser is connected to two or more tanks valve is necessary to be installed in pipeline. Diagram 5-6 illustrates this kind of connection. In short, the connection of fuel dispensers and tanks, fuel dispenser whatever working circumstance, should comply with the basic principle that one tank, one valve and one pipe are connected with one fuel dispenser. Otherwise, the normal measuring function of fuel dispenser would be affected. Diagram 5-6: Combination of two or more tanks Electric Installation The general power switch is installed indoors, switch fuse is defined as the current of motor when starting. The earthing line of fuel dispenser should firstly connect with ground device of filling station before electric installation. Power wire of fuel dispenser should connect into TN-S power supply system, compatible to TN-C-S and TN-C systems. Lead and wire should be five-bind copper thread with tw fuel dispenser o protective fuel dispenser

n a self-managed, infinitely diverting world. “I saw the people around me employing all these tricks,�?he recalls. “But they kept their tricks to themselves. Some life hackers get self-conscious about talking about it too much.�? Mr O Brien s presentation resonated with many technologists, including Merlin Mann, who started a weblog in September 2004 called 43 Folders that synthesised life hacking s high-tech perspective with that of “Getting Things Done�? a bestselling productivity book by David Allen. “Getting Things Done�?advocates breaking down all projects into single steps that can be accomplished in a few minutes and keeping track of these steps on categorised lists�? productivity software for the mind, in short. Although this kind of regimented approach is of particular appeal to geeks, it could have wider application among information workers in general. “Geeks are the canaries in the coal mine,�?says Mr Mann. “We were the first to be overwhelmed by e-mail.�?The tools used by geeks today often end up being more widely adopted tomorrow. Life hacking does not rely on the use of technology for the sake of it, however. Indeed, perhaps Mr Mann s greatest claim to fame is the ironically named “Hipster PDA”—a stack of index cards held together by a bulldog clip that is, he contends, sup fuel dispenser erior to an electronic personal organiser. Mr Mann s presentation of the idea resembles a comedy routine, but his point is a serious one there is not much fiddling, configuration and customisation to be done with a stack of index cards, so users must instead get on with doing something useful. 43 Folders—and similar sites, such as lifehacker.com—abound with similar suggestions of ways to streamline everyday processes and avoid being sidetracked (see list below). There is still room for improvement in the field, however, if the experience of its principal proponents is any guide. Mr Mann and Mr O Brien signed a contract to produce a book on life hacking for O Reilly and As fuel dispenser fuel dispenser
