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 fuel dispenser flow rate testing presents the repeatability of fuel dispenser. Error Ev should be 0.3%, repeatability of measurement no more than 0 fuel dispenser . fuel dispenser 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 12L/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

calmer days Apr 20th 2006 From The Economist print edition Uncertainty looks a bigger problem than high prices HOW high can the oil price go? It is striking that so many people are even asking the question—let alone answering it, in some cases, with frightening triple-digit numbers. For most of the 1980s and 1990s, the oil price rarely strayed far from $20 a barrel. With the exception of a brief interlude following Iraq s invasion of Kuwait in 1990, the world grew used to the joys of cheap oil. But over the past four years, the price has more than tripled, to more than $70 a barrel. It is still climbing and prices in the futures market imply that oil will remain dear for several years to come. Clearly, investors believe tha fuel dispenser t some comfortable old certainties have gone out of the window. Chief among them is the idea that Saudi Arabia will always act t fuel dispenser o fuel dispenser cap prices. The Saudis have many decades-worth of oil left in the ground, and so have an incentive to keep the stuff cheap enough to ward off conservation or substitution. To this end—and to help its protectors in Washington, DC—the kingdom used to maintain spare pumping capacity of a few million barrels a day, enough to deal with an unexpected surge in demand or a sudden cut in supply. During the first Gulf war, for example, Saudi Arabia turned on the taps to compensate for the loss of Iraq and Kuwait s normal output. But as demand has grown over the past few years, particularly from booming places like China, supply has not kept pace, so Saudi Arabia s buffer has gradually worn through. For the first time in more than two decades demand is straining at capacity. A freer oil market is no bad thing. In time, higher prices will lead to conservation—a bonus in a world worried about global warming (though one better achieved through taxes). In addition, oil firms should respond to higher prices by redoubling their efforts to procure more of the stuff. And so they are by one estimate, 15m barrels of new capacity should c
