    me fuel dispenser meter is a meter measuring liquid volume accumulatively, which consists of measurement transducer, calculator and indicator devices. When measuring liquid flow past the measured transducer, its mechanical measuring components divide flowing liquid into volume unit, then flow out together. At the same time it transforms the volume unit into relative position change value, indicating the total flowing volume by calculator and indicator devices. Measurement transducer once is called meter, which is the key parts in flow meter. 3. Additional devices Additional devices are apparatus aiming at ensure the accuracy of fuel dispenser, such as pump, oil-air separator, nozzle, solenoid valve, filter, oil indicator, pipeline, etc. 4. Ancillary devices Ancillary devices are adapted to realize other special functions of fuel dispenser, such as payment indicator, pre-setting, oil-air recovery, taxation interface, IC card read, amount indicator, zero-clear, etc. Article II Fuel dispenser’s development history Fuel dispenser is created and developed along with the development of automotive industry, petrol industry, and transportation industry. Diagram 1-1: Earlier fuel dispenser The first fuel dispenser in world, manufactured in the early of 20 century, is made of manual suction pump, transparent cylinder with scales, and switch (see the 1-1 diagram). The certain volume fuels flow into the vehicle’s tank by means of gravity, controlled by switch. The paid volume is decided by the operator eye-measuring the scales. Manual pump is replaced by motor pump until in 1920s, and the transparent cylinder by flow meter with scales (see Diagram 1-2). In 1940s, indicative handle calculator de fuel dispenser veloped as wheel calculator, function having changed from indicator volume only into measuring volume, money, and unit price adjustment as well (see Diagram 1-3). The development of electronic technique in the 1970s promotes the evolution of indicator operation and control management of fuel dispenser. The end of 20th cent fuel dispenser

    ies fuel dispenser    6.1.4.6.1 General   Any certified EEx d cable entry is accepted without further testing.   32       6.1.4.6.2 Test apparatus   An approximately cubic sealed vessel having a net volume in the range of 1 l to 10 l but not less than that of the   largest cable termination enclosure to be installed within the metering pump dispenser or remote pumping unit   with a number of holes in the side walls adapted to suit the entry devices under test or to permit blanking off if not   required. The vessel shall be equipped with gas entry and exit ports and with an ignition device to ignite the gas   centrally.   6.1.4.6.3 Test cables   If the tests are intended to cover only individual specific cablecable entry combinations the tests shall be carried   out on those particular combinations. If the tests are intended to apply to ranges of specified type of cable the   samples of cable used in the tests shall include:   � 3 cores of the largest cross-sectional area conductors that can be accommodated; and   � the largest number of the smallest cross-sectional area conductors that can be accommodated.   If the tests are intended to cover unspecified cables or cables where the cable cross section may be expected to   have gaps or leakage paths the test cable may be either as mentioned above or be a specially prepared test   sample as fuel dispenser described below whichever is considered by the testing authority to be the most onerous.   The test cable shall have at least 20 % of its cross-section unfilled and shall have a conductor configuration such   as to give the most unfavourable cond fuel dispenser

The local media say nothing that might embarrass the city authorities. A big part of the environmental problem arising from China s urban growth is that local governments and companies they associate with have little to restrain them as they rush to make money. This has encouraged the rapid outward expansion of cities, rather than the more efficient use of existing space. In name at least, rural land is collectively owned by village residents. But since unelected party officials still control most villages, it is easy for local governments to seize land and sell it to developers while giving peasants little compensation. Dongtan, as reclaimed land with no permanent population before SIIC took it over, is not tainted with such a history. And most Chongming islanders, long isolated from Shanghai s boom, doubtless welcome the government s decision to make the island s development a priority. But Shanghai s growth, and that of many other Chinese cities, has happened with little reference to public sentiment. Even as Shanghai s government plans a green haven on Chongming, it has been relocating tens of thousands of people from the city centre to make way for World Expo projects. The demand for cars is soaring as growing numbers are pushed into distant suburbs—a widespread phenomenon across China with cities rushing to build modern-looking business districts and erase Maoist-era housing. So, too, is the demand for better roads, resulting in a frenzy of construction across the country. According to Peter Head of Arup, the aim at Dongtan is to achie fuel dispenser ve an “ecological footprint�of two or less, meaning that two hectares of land would on average accommodate the consumption and waste of each person. Measuring ecological footprints is an imprecise and controversial science, but Mr Head says his target would bring Dongtan to roughly the level that would be required glo fuel dispenser
