ispenser is operated simply, putting down nozzle to start system, and nozzle automatically closed when tank is full. Other operation can be conducted on the operating keyboard, such as presetting, starting, close, inquiry and various denotations. Main components and functions Main components A fuel dispenser composed of pump, oil-air separator, flow meter (measurement transducer and counter display part), nozzle, electric system (control, transmission, operation, and display system), electric section, pipeline, oil indicator, bracket, covering, etc. Need to special explanation that fuel dispenser is a kind of delivery equipment used in flammable and combustible circumstance, thus, the electric and electrical components and their connection should be manufactured and certificated in conformance with the national explosion-proof standards so as to ensure the product security. In addition, China had stipulated that fuel dispenser from February, 1990 that the commercial fuel dispenser should have the function of tax-supervision, in accordance with the national taxation requirement so as to safeguard the reliability and security of taxation data. The key components and main principle of fuel dispenser as followed: 1-Motor 2-Pump 3-Vappor fuel dispenser separator 4-Measurement transducer 5-Sensor 6-Mechanicle/electronic counter device 7-Oil indicator 8-Nozzle Diagram 1- 20: Major components and working flow of fuel dispenser 2.2 Main components functions When the fuel dispenser’s starting component work (e.g. take off nozzle or push starting button) motor is operated and drive pump. The oil is sucked into pump chamber from underground tank, being be pressured in pump body, and flow into oil-air separator in where air was segregated from oil. The air-free oil flow into measurement transducer and impel the calculating piston move, the position movement of output axis sign corresponding to fuel filled was transmitted and converted into electric pulse sign through sensor. The pulse sign transmit to electrical counter device that r fuel dispenser

adherence to the convention is a condition of EU membership. The difficulty with this approach is that the Human Rights Act simply incorporates in British law rights laid down in a convention that Britain signed more than half a century ago. It creates no new rights. Nor does it give judges, as some have claimed, the right to strike down or annul acts of Parliament. The courts can only declare a law to be “incompatible�?with the convention, and it is then up to Parliament to decide if and how to change it. The convention itself, far from being a foreign set of principles imposed on the unwilling British, was drafted mainly by British lawyers and officials with the aim of extending to the rest of Europe the largely unwritten body of rights and liberties built up in Britain since the Magna Carta in 1215. In fact, the act s main impact has been to allow anyone in Britain—not just British citizens—to raise h fuel dispenser uman-rights issues in domestic courts rather than having to trek off to the European Court of Human Rights in Strasbourg. Mr Cameron s plan to repeal the act while staying in the ECHR would make it more difficult and costly for British residents to challenge violations of their rights, but far from impossible. M fuel dispenser r Cameron suggests that his proposed bill of rights would avoid the pitfalls of the present act by defining rights a little differently. It is hard to see how. If the bill does not provide the same rights and privileges as the ECHR does, it will be subject to an automatic challenge in Strasbourg. If, on the other hand, it extends civil liberties—which is surely not Mr Cameron s intention—then it would risk exacerbating the very imbalance between individual and collective rights that he wants to correct. The Tory leader is particularly exercised about the European court s ruling in the Chahal case in 1996. This banned Britain on human-rights grounds from deporting to India a Sikh militant, deemed a security risk in Britain. Mr Cameron claims that the Human Rights A fuel dispenser
