The l fuel dispenser argest 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 error 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 indicating 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 12 fuel dispenser L/min, respectively. Testing result is listed in Table 6-1. Table 6-1 Appraisal Results Article IV Important notices in appraisal Indicating value appraisal is crucial part of fuel dispenser’s testing items, which is direct foundation to determine the accuracy and qualification of fuel dispenser. The appraisal method and data processing introduced in Article III is based upon JJG443-98. Filling station should consult the above procedure and conduct self appraisal in accordance with relative requirements o

ld take novel solar cells closer to becoming a commercial reality. And that would be a very good thing. Production of solar cells has increased by 32% a year, on average, for the past decade and jumped by 45% in 2005. That sounds impressive, but it has been achieved largely by subsidies from the governments of Germany, Japan and California. Only in places unconnected to an electricity grid, such as much of rural Africa an fuel dispenser d rural Asia, are solar cells truly commercially viable. But if the price were to come down because efficient cells could be made from cheap fuel dispenser materials, that could change quickly. The rest of the world would then be able to join the poor of Africa and the rich of California, and generate solar power for itself. © 2006 .  About sponsorship Geothermal energy Blowing hot and cold Sep 14th 2006 | REYKJAVIK From The Economist print edition Geologists are getting more juice out of the ground GOLDILOCKS, the fussy, blonde, larcenous heroine of an English children s story, liked her porridge neither too hot, nor too cold, but just right. Most engineers looking for underground sources of steam to generate geothermal power have similar tastes. If the steam is much colder than 150°C, it will start to condense into water before it can be used to turn a turbine. On the other hand, steam hotter than 400°C, although richer in energy, is harder to find and to handle. Two new p fuel dispenser rojects, however, aim to push back both these limits. Geothermal power stations tap aquifers heated by contact with hot rocks in volcanic regions—or, in hot but dry spots, they pump water past such rocks to heat it up. The temperature of the steam produced varies, depending on how hot the source is and how much heat it loses on its way to the surface. Not all geothermal activity is hot enough to bring water to the boil. The Chena hot springs, in Alaska, for example, are just right for bathers, at a porridge-like 43°C, but n
