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 ci fuel dispenser rcumstance, 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 rel fuel dispenser iability 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 ch fuel dispenser amber 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

the specification says it has a range of values from 32 to 228. Thus if a value　　 of 0 up to and including 31 is sent then the write is rejected with an MS_Ack　　 of 5 and Data_Ack of 1.

Texas. Some of these initiatives are spreading even to the citadels of binge working, such as investment banks. Lehman Brothers has just launched a programme called “Encore�which is aimed at easing back into the industry people who have spent time out of it (which still means mostly women). The scheme offers retraining and promises part-time work thereafter. Business schools are now climbing on the bandwagon, too. In October Tuck School at Dartmouth, New Hampshire, will start a course on returning to corporate life after an extended absence. Called “Back in Business� the 16-day, $12,000 re-entry programme is open only to students with “work experience in a fuel dispenser high-potential career� The majority will inevitably be mothers wanting to rejoin the workforce. But fathers are also asking for sabbaticals. Work-life balance “is not just a women s issue�any more, says Ted Childs, who is in charge of workforce diversity at IBM. “Men, too, are very concerned about it.� The demand is being stoked by the “Generation Y� the under-28s. They look sceptically at the idea of lifetime employme fuel dispenser nt within a single organisation and they are wary of the commitment they believe too often drove their parents to the divorce courts. Hay s Ms Murlis says that today s business-school graduates are “looking for a workstyle to go with their lifestyle� not the other way round. They are happy to binge-work for a while, but in return want extended sabbaticals in which to chill out. Many of the more imaginative schemes come from organisations that are not under pressure to report quarterly to Wall Stree fuel dispenser t. Wegmans and American Century Investments are family-controlled businesses and the big accounting firms and consultancies, such as Ernst & Young, KPMG, Bain and BAH, are partnerships. This allows them to take a longer-term view of growth and costs. To some extent, the proliferation of work-life-balance schemes is a function of today s labour market.
