where air being exhausted out and oil being left. When oil level reaching a certain height, oil is controlled by floater and returned low pressure chamber. The inlet and outlet pressure disappear after fuel dispenser stopping work, check valve is closed controlled by spring. Thereby the upper oil of check valve can’t flow into high pressure chamber. Meanwhile, the taper va fuel dispenser lve on floater plug the hole at check valve seat, check valve also shut down under spring function. Under normal working situation of vapor separator, the oil flowed i fuel dispenser nto separate chamber and returned back low pressure chamber should have an equivalent volume so as to ensure the normal working of vapor separator. If the former oil volume is lower than that of latter, the exhausting pipe would flow out oil. If the oil volume in separate chamber is less than the discharge of check valve, check valve would be opened or closed, so that the accuracy of fuel dispenser will be affected due to pump’s fluctuation. If install check valve, the separate function don’t be affected, reducing flow resistance. If don’t mount check valve , However, returned oil would flow out exhausting pipe after stopping fuel dispenser, and appear cavitation in the down stream of vapor separator and pipeline so that affect next measure accuracy. Therefore, mounting a check valve is necessary to fuel dispenser’s normal operation. Some training books call check valve as outlet valve, but in this manual adapts check valve for facilitating understand. Check valve plays role to release the suddenly high pressure so as to protect hydraulic system. 3. Maintenance and troubleshooting Regularly cleaning filter is principal sector of maintenance during operation. New filling station always full of dirty and waste in tank and pipeline, fuel dispenser thus, the normal operation of fuel dispensers are affected. Thus, paying much attention to check and clean of filter. As the manufacturers made this kind of vapor separator are many, the processing method and product understanding to

a, Italy and Germany pay almost twice as much each year to transact with their banks, according to a 2005 study by Capgemini, a consulting firm. It may seem counter-intuitive, but the biggest winners from the demise of free banking may be the poor.  © 2006 .  About sponsorship Water metering Soggy politics Nov 23rd 2 fuel dispenser 006 From The Economist print edition Plans to reform water charges do not go far enough SHORTLY after Labour won power in 1997 John Prescott, the deputy pr fuel dispenser ime minister, held a “water summit�to crack down on leaks and to help deal with rising demand. Little came of it. Nine years later much of England has been in the grip of a drought, to which the response has been hose bans and ministerial exhortations to use less water. Even if a rainy winter were to refill the underground aquifers, future shortages would still be likely because of increasing population density in the south, the driest part of the country. The problem is made worse by a pricing regime that encourages households to waste water. At present most Britons pay a flat annual fee linked to the value of their homes, rather than metered charges based on how much water they use. On November 20th the government took a small step in the right direction by saying it would hold talks next year on making meters compulsory for homes in especially dry parts of Britain. The reform is overdue. Ofwat, the unattractively named water regulator, says that consumption typically declines by 5-10% in metered households. The benefits of universal metering would be widespread. The regulator reckons that two-thirds of customers would see their bills fall and that only the biggest or most extravagant families would end up having fuel dispenser to pay more. In some areas—generally the drier ones—vigorous advertising by water firms has already persuaded many people to accept meters voluntarily (see chart). But there are limits to what campaigns can achieve, and the third of
