rmance, and full-category. Article III Basic function and category Basic functions of fuel dispenser Refueling oil to vehicle and measuring the oil fueled is the basic function of fuel dispenser. Oil or fuel referrers to light fuel, such as automotive light kerosene, vehicle gasoline. Fuel dispenser, of course, also can be used to refuel other oil like above that relative to viscosity and physical and chemical capacity. Its measurement is in conforma fuel dispenser nce wi fuel dispenser th the requirement on measuring accuracy. The whole working process of fuel dispenser should be ensured because the operation medium mainly is flammable liquid, and working circumstance has combustible substance. It is obvious that delivery fuel, measurement and work safety are the basic requirements and functions to fuel dispenser. Apart from the above functions fuel dispen fuel dispenser ser has other ancillary functions, such as environmental function and oil-air recovery function. Chinese fuel dispenses have many functions, including taxation data record, memory and investigation, readout IC card, presetting fuel, communicating with upper network, or subject to upper control, receipt print, etc. with the evolution of dispensing method, the ancillary function undertake many variety, which mirrors the major improvement of fuel dispenser. fuel dispenser’s category Fuel dispenser can be divided into various categories according to its configuration and function. It is divided into mechanical fuel dispenser (Diagram 1-3, 1-14), and electronic fuel dispenser (displayed and operated by electronic components) according to counter indicator and operation configuration. Owing to the inherent defects of mechanical counter and operation, mechanical fuel dispenser has rapidly been replaced by the electronic one, commercial fuel dispenser in particular. There are the general fuel dispenser�40-60L/min. and large flowage fuel dispenser with 80-90L/min in terms of delivery capacity. By the number of fuel unit and nozzle mounted, fuel dispenser include single nozzle

police raids, arrests and the investigation into allegations that at least �00m ($265m) was siphoned out of secret bank accounts in Liechtenstein, Austria and Switzerland. A page-turning airport thriller? No, the 20-F filing submitted by Siemens, a German conglomerate, to the Securities and Exchange Commission in Washington, DC on December 11th. At the same time, the firm restated its earnings to take account of uncertainties over transactions being inv fuel dispenser estiga fuel dispenser ted by state prosecutors in at least three countries. The purpose of these murky dealings remains unclear was it a case of self-enrichment by crooked employees or something more sinister—carefully laundered bribes to win Siemens business in some of the 190 countries in which it operates? Siemens insists that it was a victim of crime not an accessory to it. It is investigat fuel dispenser ing �20m of suspicious payments to consultants over the past seven years. Meanwhile, six present and former employees, including one former board member arrested on December 12th, are in custody. In the flow of adverse publicity since police raided 30 of its offices a month ago, Siemens has tried to show that it is taking appropriate action. It announced the formation of a “task force�to clarify and standardise its employees business practices. It also appointed an ombudsman to encourage internal whistleblowing. But for Transparency International (TI), an anti-corruption campaign group, this was not enough. It had already suspended Siemens s membership of its German chapter in 2004 because of the company s reluctance to be transparent about an unresolved bribery case in Italy. (The case was settled last month without admission of guilt.) Siemens s sluggish reaction to investigations in Liechtenstein triggered a letter last month from TI warning that the firm s membership would be liable for termination after December 15th. At an emergency board meeting this week Siemens announced new measures to show how determined it is to change its culture. It appoi
