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 toleranc fuel dispenser es. This relation between tolerance and flux is called the tolerance nature of flo fuel dispenser w 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 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 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.

positions on everything under the sun—though he briefly stopped taking money from the NRA in the aftermath of the Columbine shootings, which took place a few blocks from his house. He started his political career in the Colorado statehouse as a member of a group called “The Crazies�because of their fervent opposition to taxes. He signed a pledge calling for the elimination of public schools, despite the fact that both he and his wife had once taught in them, suggested bombing Mecca in retaliation for terrorism, a fuel dispenser nd regularly voted against George Bush s “big government�legislation. But where fuel dispenser Mr Tancredo has really made his mark—where he puts his red-faced fervour on full display—is on the subject of immigration. Mr Tancredo has been furious about immigration since 1975, when he was a high-school social- studies teacher and the Colorado legislature passed the country s first bilingual education law. This liberal over-reach not only offended his heartfelt belief that immigration must be balanced by assimilation (Mr Tancredo is himself the grandson of Italian immigrants who came to America without being able to speak English). It provided him with a subject that has driven his political career. Mr Tancredo doesn t stop at building fences and opposing guest-workers. He opposes birth-right citizenship (whereby babies born in the United States automatically become American citizens). He wants to deploy American troops along the border with Mexico. And he regularly salutes the Minutemen who unofficially do the job now as “heroes...not vigilantes� Mr Tancredo s beliefs and behaviour at first consigned him to the margins of Washington life. His immigration caucus attracted only 16 members. He frequently found himself giving speeches on immigration to an empty chamber (though the ever-present C-Span camera made it worthwhile). Karl Rove, Mr Bush s chief adviser, was so angry about his anti-immigration stance that he told him fuel dispenser that he would never “darken the doorstep of the Wh
