bolt is first step as measurement accuracy beyond scope. If it doesn’t work, consider other solutions. 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 measur fuel dispenser ing 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 cas fuel dispenser e, fuel dispenser delivery more oil than flow measured. Oil full of colloid is also affected the normal 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 measuremen fuel dispenser t 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 abrasion 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.

on fears whipping through global markets. Inflationary expectations, measured by the difference between index-linked and coupon-bearing bonds, fell from mid- May until this week, even after Mr Bernanke issued a stern warning that increases in core inflation were “unwelcome developments� Gold prices, which are often a hedge against inflation, also fell. There have been other curiosities about the performance of fina fuel dispenser ncial markets that have made it difficult to gauge the seriousness of the sell-off. Stockmarket investors have expressed concern that the Fed, anxious to prove its inflation-fighting credentials, may tighten a notch or two too far, just as its prior fuel dispenser moves over the past two years begin to take a toll on economic growth. Already, there are indications that the housing market and consumer spending are cooling. Yet concerns about a sharp slowdown in growth are not fully reflected in other markets. Corporate bonds, for example, have outpe fuel dispenser rformed shares, giving few indications that economic hardship will raise default rates. Thomson Financial, a data compiler, says that upgrades to corporate-earnings forecasts are still exceeding downgrades in every big stockmarket except Britain s, which hardly indicates pessimism about the world economy. Earnings yields, too, are attractive compared with bond yields, says Peter Oppenheimer, a strategist at Goldman Sachs. “If you look at the numbers, you wonder why people are as worried as they are.� A look at the markets long-term performance provides further pause for thought. For some investors, the short-term pain is indeed intense. The sufferers include funds that have borrowed a lot and bought shares and commodities shortly before their prices began to tumble. They also include those who sold derivatives offering insurance against falling prices when the sell-off began. Analysts say the selling of derivatives, as much as any other factor, exacerbated the drop in share prices early this week. On June 13th the Dow Jones Industrial A
