ct before switching on suction pum fuel dispenser p. After oil being sucked up carefully inspect all connection and sealed sections whether exists leakage. Scrutinize the working states of measurement transducer, pump and vapor separator after starting operation. As for new filing station, clean waster and water in pipeline. Preset unit price according to oil price. It is regulative to twice PPU presetting for each fuel dispenser per day. Appraise each nozzle flow rate in accordance with fuel dispenser’s metrological regulation and procedure, indicating value error no more than ±0.3%, repeatability error no more than ±0.15%. Regulate the adjusting bolt of overflow valve to change flow rate, increasing or reducing it. It must switch off power supply to maintain failure in debugging progress. It is strictly prohibited to debug as explosion-proof junction box being open. Debug personnel should clearly tell all operating functions and methods of fuel dispensers to station staff, and make report to station owner and get authorization. Chapter VI Metrological approval of fuel dispenser As commercial measure instrument, fuel dispenser is used for calculating the volume of commercial-used fuel. Thus, its accuracy directly correlates the customer’s economical benefits. That is the reason why fuel dispenser in China should be conducted a compulsory appraisal in accordance with State’s law on metrology. Metrology aims at ensuring exactitude on basis of united unit. The metrological appraisal for fuel dispenser refers to the work that to appraise measurement performance and to inspect whether or not abiding by legal requirements. The metrological regulation on fuel dispenser JJG 443-98 (hereinafter called JJG443-98) promulgated in Aug 1, 1998, is a legal tool to appraise metering of fuel dispenser, which intro fuel dispenser duces the international metrological technology regulation and global practice. JJG 443-98 emphasized that flow meter is core component in fuel dispenser, enhances metrological requirement, increasing the cont fuel dispenser

ng about New York in the 1920s, H fuel dispenser ong Kong in the 1980s, or one of the booming cities in Asia that, according to Emporis, a firm which tracks skyscrapers, now lead a boom in high-rise building undaunted by the attack on the World Trade Centre in 2001. Roughly 8% of the world s stock of tall buildings is currently under construction, according to Emporis. About 40% of the world s 200 tallest buildings have been completed since 2000. Skyscrapers pose stupendous problems to designers and developers because they have two powerful forces working against them. The first is economic—exemplified by the number of big American companies that now prefer to operate from low-rise campuses built outside cities. There are of course exceptions. These tend to be large financial institutions, on which a skyscraper confers the permanence once embodied by marble halls and oak- panelled dining-rooms. The second is physical towers are always fighting against their own weight. As more parts of the building are devoted to holding it up, they encroach on the space for working or living in. Developers and leasing agents refer to the ratio between these two elements as a building s “net-to-gross� In a really efficient skyscraper, nearly 70% of the building s volume is useable, with the rest taken up by lift-shafts, stairwells and pillars. In a well designed low-rise building, by contrast, more than 80% of the space can be sold or let. These obstacles explain why, in each skyscraper boom, many more designs are proposed than built. London, for example, has five towers over 200 metres (656 feet) tall that either have planning permission or are in the planning process, by which stage they must have completed designs and a willing developer. Yet only a couple of them are likely to be built. Francis Salway, fuel dispenser chief executive of Land Securities, a developer, predicts that “between one and three�will go up over the next decade. A lot has still to happen before a tower can metamorphose from a design with enthusia fuel dispenser
