The largest value of Error Ev in testing is regarded as the basic error of fuel dispenser according to the regulation of JJG443-98. The larger value of Repeatability of measurement En in two flow rate testing presents the repeatability of fuel dispenser. Error Ev should be 0.3%, repeatability of measurement no more than 0.15%, if beyond these scopes testing would be determined as unqualified. The contents of money indication and money er fuel dispenser ror are not regulated in the approval procedure of JJG443-98. There would exist a little error after long refueling because usually the calculation of paid money adapts the round –mode. Example of indi fuel dispenser cating valve appraisal Take an appraisal of fuel dispenser 6~60L/min for example, it is usually adapted non-presetting mode in filing station. Setting unit price as 2.75�L and preparing metal standard measurer of 100L, conduct 3 tests as maximum flow rate 60L/min and minimum flow rate 12L/min, respectively. Testing result is listed in Table 6-1.

ped up, and several nightclubs have opened. Just a few blocks away stands the restored, and highly successful, Fox Theatre. Around 50 new businesses and 600 new housing units may not seem much in booming cities like New York or Chicago. In Detroit, though, the revival is something of a miracle. Coleman Young, who was mayor for five terms in the 1970s and 1980s, tried hard to rebuild the once-grand downtown, but many of his efforts were frustrated. Potential residents didn t want to move to the inner city without shops, restaurants and entertainment; businessmen didn t want to set up shop without a nearby base of potential customers. The 1988 reopening of the Fox began to change that equation, but the biggest boon was the 2003 relocation of Compuware, a huge computer-services company, from the suburbs to a space on Woodward near the river. Compuware has added just enough critical mass to spur a visible resurgence downtown. New housing is now moving up the wide boulevard, and even fuel dispenser a long- abandoned neighbourhood of Victorian townhouses is suddenly being rebuilt from little more than rubble.

Rather desperately, city officials are now busi fuel dispenser ly redecorating many of the still-empty shopfronts, so that things look a little better for the big weekend. For behind all the signs of revival, bad news persists. Carmaking is in a deep slump; even in the elegant suburb of West Bloomfield, the deep job cuts under way at Ford and General Motors have made it hard to sell a house. That decline hits the city of Detroit especially hard, since it depends disproportionately on income-tax revenues from workers at places like the Renaissance Centre, the riverfront headquarters of GM. Across the city the tax base is shrinking, even as the current mayor, Kwame Kilpatrick, struggles to balance his budget by slashing the number of police and firemen and lopping off other city services. Despite the new downtown housing in places like Woodward Avenue, the census shows that arou fuel dispenser
