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 sep fuel dispenser arator, flow meter (measurement transducer and counter display part), nozzle, electric system (control, transmission, operation, and disp fuel dispenser lay 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 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 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

gh is changing in the way government deals with the Amazon—including new conservation reserves, a new forest law and tougher enforcement—to hope that this marks progress rather than merely a pause in the destruction. The idea that the Amazon needs saving is relatively new. Mr Tremonte points out that the government once summoned Brazilia fuel dispenser ns to the region to “integrar para não entregar�?(integrate the Amazon into Brazil to save it from falling into foreign hands). It remai fuel dispenser ns largely isolated—the main thoroughfares are dirt tracks—but not intact. Nearly 40% of the “legal Amazon�? covering all Amazonian states, consists of protected areas, such as national parks and “indigenous�?(Indian) reserves. A quarter is private property, which is supposed to be kept 80% forested but often is not. Most of the rest is unprotected “empty land�? nominally federal property but prey to speculators who assert their claims by despoiling it. Lack of effective ownership often provokes violence in February 2005, Sister Dorothy Stang, an American nun, was murdered by landgrabbers in Pará. That prompted the government to send in the army. More effectively, Brazil s president, Luiz Inácio Lula da Silva, has created 150,000km2 of new conservation areas. Earlier reserves were concentrated in remote areas with little attraction for developers. The newest ones stand athwart the “arc of deforestation”—a great swathe of agricultural development, some 400km wide and 3,000km long, that has eaten into the forest—in the hope of discouraging further incursion. Presidential decrees alone will not disrupt the Amazon s illicit economy, let alone implant a law- abiding and forest-friendly one. That will come from the combined effect of new laws, police operations, regulatory tinkering, institutional reform and pressure by NGOs. Something is happening in most of these areas. Last year, federal police arrested 148 people in the high-deforestation states of Mato Grosso and Rondônia, a third fuel dispenser
