bolt is first step as measurement accuracy beyond scope. If it doesn’t work, consider other so fuel dispenser lutions. Some oil is easily full of colloid due to not in accordance with national standard or exposing to air in long storage. Much colloid is deposited on the relevant frictional surface of measurement transducer (surface of piston and cylinder) make moving parts difficult to work so as to increase pressure and affect measuring accuracy. The inlet pressure of measurement transducer usually is little under small flow rate. However, piston resistance is increased due to extensive colloid, even easily appear the phenomenon of refueling without measurement related. In this case, fuel dispenser delivery more oil than flow measured. Oil full of colloid is also affected the norm fuel dispenser al operation of vehicle motor. The cardinal solution to this problem is to control the quality and storage time of oil. Carefully clean the colloid on relative frictional surface of measurement transducer as occur the problem, and especially pay much attention to the friction surface so as not to damage mechanical parts. 1-Outlet elbow 2-End cover 3-Piston 4-Frame 5-Connecting sheet 6-Lower connecting rod 7-Upper connecting rod 8-Cylinder bushing 9-Adjusting bolt 10-Cap nut 11-Regualting piston 12-Driving elbow 13-Brass bushing 14-O-ring 15-Output shaft 16-Nylon wheel Diagram 2-19: Structural drawing of another kind of metal piston measurement transducer Accuracy decline and leakage caused by mechanical failure. The extensive mechanical abrasion of relevant friction surface of measurement transducer is main reason of causing accuracy beyond limitation. These parts abrasi fuel dispenser on result in accuracy decline, such as connecting board, bushing, small brass bushing used as adjusting piston, regulative piston, nylon wheel, etc. The O-rings between connecting rod and piston and on driving elbow tend to expansion to affect accuracy. Generally, disassemble and inspect all components, problem will be solved by changing extensive abrasion or damaged parts.

option, were so reluctant to embrace texting. But now they have adopted the technology fuel dispenser with enthusiasm. What happened? America s apathy towards texting was easy to explain. Voice calls on mobile phones are cheaper than in other countries, which gives cost- conscious users less incentive to send texts instead; several different and incompatible wireless technologies are in use, which made sending messages from one network to another unreliable or impossible; and texting was often an additional service that subscribers had to sign up for. As a result, the number of messages sent per subscriber per month was just over seven in December 2002, compared with a global average fuel dispenser of around 30. But things have since changed, with that figure rising to 13 in December 2003, 26 in December 2004, and 38 in June 2005, the most recent date for which figures are available from the Cellular Telecommunications Industry Association, an industry body. So America has now overtaken Germany, Italy and France in its enthusiasm for texting. There are several reasons for this. “We ve had that penetration of the youth market,�says Brian Modoff, an analyst at Deutsche Bank. “We didn t have that until a couple of years ago.�Family calling plans and other new tariffs have put phones in the hands of more young people, who are more likely to adopt texting. There have also been technical changes GSM, the text-friendly wireless technology used in Europe, has become far more widespread in Amer fuel dispenser ica as operators have switched customers to it from older technologies, notes John Tysoe of The Mobile World, a consultancy. Interconnections between networks have improved too. But perhaps the most surprising factor is the role of reality television—and in particular, “American Idol� a talent show in which viewers phone in to vote f
