    erance not exceed ±0.3%,repeated measuring no more than 0.15% as fuel dispenser is operated within the flow range between maximum flow-rate (Qmax) and minimum flow-rate (Qmin). Flux scope is also called measurable range --- between minimum measured value and maximum flow-rate within basic tolerance. The ratio of maximum flow rate to minimum flow rate is called measurable ratio. In model testing the value is 10 to 1. Accuracy testing is conducted at six flow points within the measurable range so as to get their tolerances. This relation between tolerance and flux is called the tolerance nature of flow meter. The less flow tolerance the better. Measurable range ratio is 10 to 1 as fuel disp fuel dispenser enser being left factory, testing three flux points, that is, Qmax, 0.4 Qmax, 0.1 Qmax . However, the ratio in operation place is 5 to 1, only testing two flow points -- Qmax , 0.2 Qmax . Minimum measured volume testing Testing purpose is to assess indicative tolerance when refueling by minimum measured value. Relevant regulations stipulate that the minimum flow rate don’t surplus 5L as for a fuel dispenser with maximum flow rate no more than 60L. Its maximum tolerance in terms of minimum measured value don’t exceed ±0.5%, measurable repeatability no more than ±0.25%. Flow stoppage testing The testing is conducted in order to define the possible tolerance range that generated in refueling progress in which hydraulic flow stop sudde fuel dispenser nly due to some accidents like power cut. Vapor separator performance testing It is conducted to value the capacity of vapor separator how much vapor would be divided from oil. Vapor separator’s function is to ensure that media passing over flow meter should be in single direction without any foam or bubble. Otherwise, flow meter can’t get right value of measurement. Volume fluctuation testing The test is aimed at defining the hose’s inner cubage variability of fuel dispenser under maximum pressure condition. According to fuel dispenser’s working principal, hose always fuel dispenser

    he law may well be ineffective. -holders may step in at Apple s behest and prevent their music being played on rival devices. If it has any effect, the law may backfire. For Apple, France is a dispensable nation. The company could quit the country altogether rather than allow its competitors to take advantage of its music store. As a result, the law may leave France s digital music- lovers with less choice, not more. Put these practical difficulties aside, and ask whether France s policymakers identified a real problem. Are they right to worry about the inseparability of Apple s store and its player? Such controversies normally turn on the analogy chosen to illuminate them is fuel dispenser the iPod like a CD or cassette player, or an inkjet printer? Since it appeared in 2001, the iPod has become this decade s answer to the Sony Walkman. Supporters of the French law point out that if you buy a music cassette at a shop, you can listen to it on any cassette player that takes your fancy. You do not have to play it on a Walkman. Why then can customers not listen to songs from Apple s music store on whatever player they like? Surely Apple is guilty of exploiting the popularity of its store to stifle rivals to its iPod? The law s opponents reach for different analogies. They compare the iPod not to the Walkman, but to printers, games consoles and razors. Buy an inkjet printer, for example, and you must buy the manufacture fuel dispenser r s cartridges to be sure that it will work properly. (Although French parliamentarians will not come to your rescue, European regulators might.) Indeed, manufacturers make much of their money from the cartridges, not the printer itself, which is often sold cheaply. Economists explain this business model as a clever way for companies to “meter?their customers, charging them according to use. If they could not tie their customers to their cartridges, they would charge more for the printer itself, and the kind of person who now uses his printer rarely would not buy one at all.
