ecord and display the volume of present and total filing (either volume or sale). Finally, the oil was measured and flowed out of nozzle via solenoid valve and oil indicator. The operator conducts the starting, close and control flow-rate; oil indicator is device used for air and foam check through eyes. Solenoid valve is mounted for preventing in presetting fuel from affecting accuracy due to the inertial of fuel. Fuel dispenser with submersible pump to delivery oil together, its motor and pump is operated by the nozzle or starting key. Submersible pump delivers pressured oil to many fuel dispensers, in this kind of fuel dispenser delivered through positive pressure dot need to install built-in oil �air separator, pump and motor, but the rest of components is similar to suction pump fuel dispenser. Fuel dispenser’s design, manufacture, appraisal standard and certification Fuel dispenser belongs to one kind of legislative commercial measurements, which should be compulsorily appraised and managed through technology supervision departments at state and all levels. The design, manufacture and appraisal of fuel dispenser is in accordance with the relevant national provisions, standard and regulations, namely, National Standard GB/T9081-2001 Fuel Dispenser for Vehicle; National Standard GB3836-2000 electric Apparatus for explosion gas atmosphere; procedure of measurement appraisal for fuel dis fuel dispenser penser JJG443-1998; Measurement technology regulations JJF1060-1999 Appraisal outline of tax-supervision fuel dispenser. Appraised fuel dispenser should obtain the manufacture licensing for measurement instrument issued by the state quality inspect fuel dispenser ion administration; whole frame and components including explosion-proof parts should achieve the certificate of explosion-proof; domestic fuel dispenser employed in commercial filling station should attain the certificate of taxation function issued by the State Taxation Administration.

o squabble over space disagree about why there are more species in the tropics than anywhere else. To them, the tropics are either where species are more often born (cradles of diversity) or where they tend not to die (museums of diversity). By contrast, biologists concerned with patterns in time tenaciously debate whether new species come into being in a smooth and gradual manner, or whether the history of life is actually a series of bursts of change that are interspersed with periods when nothing much happens. Two papers just published in Science have cast light on these questions, and their findings, if not necessarily resulting in compromise, do show the value of taking leaves out of other people s books. The “space biologists�have looked into time, namely the fossil record over the past 11m years. Meanwhile the “time biologists�have looked at the here and now and found evidence in living species for periods of rapid evolution in their genes. Biological spacetime The space biologists have the advantage that they agree about the pattern they are trying to explain. Almost all groups of life that have been studied—be they fungi, plants, vertebrates or invertebrates, and no matter whether they occur in forests, streams or seas—seem to have more species the closer they are to the equator. To decide whether the tropics are a cradle or a museum, though, involves picking t fuel dispenser his pattern apart with statistics. And statistics work best when you have more than one sample. That is the reason for reaching into the past. David Jablonski, of the University of Chicago, and his colleagues created their samples by dividing t fuel dispenser he past 11m years into three periods. For simplicity s sake, they also chopped the Earth s surface into two tropical regions and everywhere else, which they called the “extratropics� To avoid sampling bias, they restricted their analysis to one group of animals—the bivalve molluscs—that fossilise well. This allowed them to follow 431 “lineages? fuel dispenser
