ct before switching on suction pump. After oil being sucked up carefully inspect all connection and sealed sections whether exists leakage. Scrutinize the working states of measurement transducer, pump and vapor separator after starting operation. As for new filing station, clean waster and water in pipeline. Preset unit price according to oil price. It is regulative to twice PPU presetting for each fuel dispenser per day. Appraise each nozzle flow rate in accordance with fuel dispenser’s metrological regulation and procedure, indicating value error no more than ±0.3%, repeatability error no more than ±0.15%. Regulate the adjusting bolt of overflow valve to change flow rate, increasing or reducing it. It must switch off power supply to maintain failure in debugging progress. It is strictly pro fuel dispenser hibited to debug as explosion-proof junction box being open. Debug personnel should clearly tell all operating functions and me fuel dispenser thods of fuel dispensers to station staff, and make report to station owner and get authorization. Chapter VI Metrological approval of fuel dispenser As commercial measure instrument, fuel dispenser is used for calculating the volume of commercial-used fuel. Thus, its accuracy directly correlates the customer’s economical benefits. That is the reason why fuel dispenser in China should be conducted a compulsory appraisal in accordance with State’s law on metrology. Metrology aims at ensuring exactitude on basis of united unit. The metrological appraisal for fuel dispenser refers to the work that to appraise measurement performance and to inspect whether or not abiding by legal requirements. The metrological regulation on fuel dispenser JJG 443-98 (hereinafter called JJG443-98) promulgated in Aug 1, 1998, is a legal tool to appraise metering of fuel dispenser, which introduces the international metrological technology regulation and global practice. JJG 443-98 emphasized that flow meter is core component in fuel dispenser, enhances metrological requirement, increasing the cont fuel dispenser

itain in 1956 to end the Suez venture. Jimmy Carter punished the Soviet Union after its invasion of Afghanistan in 1980 with a wheat embargo and an Olympic boycott. Ronald Reagan imposed them in protest at martial law in Poland. Congress, too, came to see sanctions as an easy, cheap way of expressing ire. In 1996, for example, Belize, Colombia, Costa Rica, Italy, Japan, Mexico, Panama, Vanuatu and Venezuela were all under American embargo for beastliness to whales or dolphins. In the next five years America imposed 85 new sanctions on foreign states. Sanctions may feel better than nothing they are less feeble than scolding an ambassador and less bloody than sending in the marines. They provide a frisson of moral satisfaction. And sometimes they work—ending Britain s Suez foray, for example. fuel dispenser The threat of penalties by city and state officials in America in 1998 forced a group of Swiss banks to cough up $1.25 billion f fuel dispenser or some Holocaust survivors. Libya s return to respectability may have owed something to sanctions. They played a part in ending white rule in South Africa too. Spotting the failures is easier. The League of Nations sanctions did not protect Abyssinia against fascist Italy. The United Nations did no better with Saddam Hussein s Iraq. Harsh regimes are still in place in Iran (under American embargo since 1979), Myanmar (since 1997), Sudan (since 1996), never mind Cuba (1962). Regime change may not be sanctions aim; behaviour change may suffice. Even so, snags abound. The morality of punishing poor people who live in a boycotted autocracy is dubious. It may make the regime more popular or powerful. Mr Hussein easily ensured that sanctions hurt chiefly the innocent. Scarcity provides an excuse for rationing, permits and licences, creating corruption, favouritism and a black market which the regime can control. In Slobodan Milosevic s Yugoslavia, sanctions virtually fused the state with the criminal class. Sanctions may have other results too. Arms embargoes turned fuel dispenser Sout
