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 mini fuel dispenser mum flow rate is called measurable ratio. In model testing the value is 10 to 1. Accuracy testing is conducted a fuel dispenser t 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 dispenser 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 surplu fuel dispenser s 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 suddenly 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

a new one. Thanks to the Poles, that will not now happen. Russia is still keen. It signed the present partnership agreement at a time when decision-makers in the Kremlin were talking of “a common European house� and both sides thought that common values and European norms could be the basis of their relationship. But the Russians no fuel dispenser longer accept this. Mr Putin is always banging on about Russia s specific form of democracy. This week he repe fuel dispenser ated that “it would be useless and wrong to try to force artificial standards on each other.�Rather like the hangdog American comedian, Rodney Dangerfield, he seems to be fretting that “I don t get no respect.� Many Europeans also want a new agreement, on the ground that it might help to overcome recent difficulties with Russia*. But the Poles disagree. They do not trust the Russians; they believe that toughness is the only language these people understand; and they do not want the EU to sign a treaty that could water down Europe s promotion of human rights and democracy. To its partners dismay, Poland this wee fuel dispenser k continued to withhold support for formal authority to negotiate a new partnership agreement. The notion of simply not bothering with a new treaty is far from absurd, especially now that Russia has reached agreement with its main partners (though not Moldova or Georgia, see article) on its entry into the World Trade Organisation. WTO membership would anchor it in the international trading system, with no need for special help from the EU. Russia and America do not have an overarching agreement, just a series of specific, security-related, accords. Many things that the Russians and the EU do together either do not need a comprehensive agreement or (as with security matters) would not be included anyway. Negotiations on a new comprehensive treaty would themselves be protracted and antagonistic, since they would inevitably bring into the open simmering differences over shared values, and would risk exposing Europe s own intern
