me meter is a meter measuring liquid volume accumulatively, which consists of measurement transducer, fuel dispenser 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 veh fuel dispenser icle’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 i fuel dispenser ndicator 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

ouble. The Muslim Brotherhood captured 88 seats, a record for the opposition in Egypt, and would cer fuel dispenser tainly have gained more without blunt government obstruction of the polling. Still officially illegal, the group continues to be hounded by serial detention of its activists. Recent arrests have included dozens of student An angered Copt knows whom to leaders, as well as five publishers sympathetic to the blame Brotherhood, who were rounded up in advance of voting in a publishers trade organisation. Oddly enough, the regime has also squashed opposition parties with far less organisational strength or popular appeal than the Brotherhood. Earlier this month, a state-appointed court rejected applications to form political parties filed by mild Islamists and by secular Arab nationalists. Many observers blame government manipulation for the bitter leadership struggle that has crippled the Wafd Party, a traditional voice for liberal secularism. On April 1st, followers of one faction stormed the party headquarters, sparking a shoot-out. Several dozen were injured. The opposition s weakness has led many reform-minded Egyptians to pin hopes on more narrowly focused pressure groups from outside the formal political system. Several such groups have emerged in recent years, including unions of university teachers protesting against the interference of security agen fuel dispenser cies in academia, and journalists demanding an end to the imposition of harsh prison terms for libel. Despite constant coercion from the ministry of justice, Egypt s 9,000 judges are pressing for the adoption of a law establishing full judicial independence. Having stalled on the issue for over a decade, the ministry recently ordered two of the fuel dispenser country s most senior judges to appear before a disciplinary board. Although no formal charges have been aired, the pair s apparent crime is to have protested against blatant, government-sponsored fraud during the parliamentary elections, which were ostensibly monit
