wing measuring requirements: Instrument of measurement should have a certain tension and not easily be deformed so as to affect the inner cubage volume. Foam and vapor that dissolved in fuel measured are able fuel dispenser to be discharged completely when pouring into instrument of measurement. Liquid measured should be discharged after measu fuel dispenser rement, only a bit being left in container. Valve of instrument of measurement should have reliable sealability without leakage phenomenon as being full of oil. Indicating pipe on measurer should be made of glass without defect on inner diameter so as to hinder observation. Connection between measuring neck and scale should be fixed in order to keep stably relative position. The line on indicating glass should be legible and clear, width being no more than 0.25mm. The inner of measuring neck is depended upon measurer’s accuracy. As for Class II metal standard measurer, the ratio of corresponding liquid volume of per millimeter to measurable volume of measurer is no more than 5×10�. Discharge time of measurer relies on the diameter of bottom valve. It is leaned from experiment that the longer time of unload the less residual liquid left, better promoting measurement accuracy, and vice versa. Thereby, in order to control the tolerance occurred by discharge velocity and time and residual volume during approval progress, discharge condition and pouring-out time is regulated generally that op fuel dispenser ening fully bottom valve start to count two minutes from liquid dropping, then close bottom valve; or fully open bottom valve and close it after 3 minutes. Indicated value generally read out as showed at the bottom of curve in indicating glass. Apart from standard measurer applied in fuel dispenser inspection and approval, there is thermometer or temperature sensor, measured range �0�to �0� minimum value 0.2� which used to measure temperatures of liquid that passed over nozzle vent and in standard measurer. One of purpose to measure temperature is to make modification of

bars entry to the site, however, and some pitches have barbed wire around their perimeters. Grattan Puxon, a member of the Gypsy Council, says the residents feel besieged and it is easy to see why. But so d fuel dispenser o some of their non-travelling neighbours. Basildon District Council, which is responsible for the Dale Farm site, voted fuel dispenser last year to evict its illegal residents, at a cost of £1.9m. Malcolm Buckley, who leads the Conservative council, says that Basildon provides more pitches than most local authorities do, but the district is now full. Yet Richie Sheridan, a spokesman for those at Dale Farm, says that many very old, very young and very sick people live at the site and have nowhere else to go. The travellers are now awaiting judicial review of the council s decision to evict them, which could come as early as May. The Commission for Racial Equality is intervening in the proceedings to make sure the court takes into account the council s legal obligation to promote good race relations. A much publicised ruling by the House of Lords in March that another group of travellers was not entitled, under human rights law, to remain on land they had occupied illegally is reckoned too different in its particulars to affect the outcome of this review. These cases are only two of many. In 1994 the government abolished the statutory requirement that local authorities provide sites for gypsies, and the number of s fuel dispenser ites duly fell. The Office of the Deputy Prime Minister (ODPM) estimates that only 74% of the 16,000 traveller caravans in Britain are on authorised sites. Some 13% of the rest are on sites like Dale Farm, where the travellers own the land but do not have planning permission to live on it, and the remaining 13% camp illegally on other people s property. The ODPM reckons that another 4,000 pitches are needed. Last month, the ODPM told local authorities that they should provide sites, even though they were not strictly required in law to do so. Dale Farm residents, together with others r
