me 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 uni fuel dispenser t 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 fuel dispenser ’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 developed 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

For　　 non-armoured cables this shall be reduced to a maximum radius of 100 mm.　　4.7.3 Cable Flame Retardant Certification　　 IEC 332 defines a number of tests to certify the flame-retardant behaviour of cables.　　 The designation after the number e.g. IEC 332-1 and IEC 332-3 defines which test has　　 been performed. Obviously the class 3 test is much more severe than that for class 1.　　 Many statutory bodies in Europe stipulate IEC 332-3 cable for its flame-retardant　　 specification. It is also required that the cable be labelled with the text IEC 332-3 or　　 IEC 332-1 as required. Please note that most cables are self-certified by the　　 manufacturer and not by an independent third party organisation.　　4.7.4 Use of Common Ducting　　 fuel dispenser There are obvious commercial benefits if it is possible to use the same ducts for both　　 power and data cables. European wiring regulations (CENELEC HD 384) permit such　　 use of common ducts for power cables and data cables but not for fire alarm or　　 emergency lighting cables provided that the data cables are insulated to the same　　 standard as the corresponding power cables or are separated from power cables by an　　 earthed metallic screen.

eover, net outflows from Japan of investment in fixed-income bonds have actually declined this year—especially in the past few months. Mr Jen has an alternative explanation for why the yen is so feeble against the euro the “global funnelling hypothesis� This focuses on the net trade and capital flows of Asian and oil-exporting coun fuel dispenser tries, which could run a combined current-account surplus of around $900 billion this year. In simple terms, the world buys from these countries and they then invest the net proceeds in financial markets. Most international trade is settled in dollars or euros, so importers have to sell their local currencies in order to buy from abroad. Mr Jen calls these “upstream currency flows� “Downstream flows� in contrast, are what Asia and oil exporters do with their accumulated reserves. The currency compositions of the two flows do not necessarily match. Because Asian countries trade a lot with each other, the bulk of upstream flows involves the selling of yen and other Asian currencies. In contrast, most downstream flows go into dollars and euros. Central banks prefer to put money into well-developed financial markets, so the liquid and secure markets of America, the euro area and Britain attract more capital. This causes a funnelling from Asian currencies into dollars and euros. Emerging economies rising foreign reserves therefore push the yen down against t fuel dispenser he euro, regardless of fair-value calculations. This also explains the strength of the pound. Recent figures show that it has knocked the yen off its perch as the world s third most popular reserve currency. If correct, this theory suggests that the yen could remain weak for longer than many analysts expect. In the long term, however, the yen s huge undervaluation means that it will eventually bounce back. Last week was the 21st birthday of the G7 s Plaza Accord, which triggered a huge rise in the yen. The yen is much more undervalued today than it was then. © fuel dispenser
