oil, so as to reduce the volume of drained oil. Turn adjusting bolt clockwise to reduce discharge, anticlockwise to increase discharge. Therefore, changing the position of bolt enable discharge approach academic volume and reach fuel dispenser the requirements on measurement transducer of national appraisal regulations. As two regulative bolts access to adjusting piston, the adjusting discharge in a circulation per bolt can be calculated in the following formula: △V = 1/2πd12 nt (2--4 ) △V ── adjusting value in per circulation; D1 ── diameter of regulative piston; n ── turning number of adjusting bolt; t ── screw- pitch of adjusting bolt. There is another metal piston measurement transducer in current market. See the Diagram 2-19. Regulative piston is singularly installed in piston rather than connect with rod in this mo fuel dispenser del. Its adjusting value in terms of per adjusting bolt is: △V = 1/4πd2 nt (2--5 ) Common failure and Troubleshooting Metal piston measurement transducer has the two common failures --- accuracy decline and mechanical trouble. Measure accuracy beyond scope The allowed measurement accuracy of fuel dispenser is ±0.3 %, repeated tolerance no more than 0.15 % according to the stipulation of JJG443-98 Fuel dispenser. The maximum allowed tolerance of min. measured valve don’t exceed ±0.5 %，its repeated tolerance no more than 0.25 %. The ratio of maximum flow (Q max.) to minimum flow (Q min.) is 10 to 1. as fuel disp fuel dispenser enser leave factory. The ratio should not be less than 5: 1 in inspecting at operation locale. All of exceeded tolerance is regarded as beyond measurement accuracy. There are many elements and reasons resulting in measurement accuracy beyond scope, including unstable hydraulic system (extensive pressure fluctuation), electric system failure, thick colloid in frictional interface, measurement transducer abrasion, etc. The last two reasons will mainly be introduced in this article. Regulating adjusting

n. Bayer, which has offered to buy Schering for �7 billion, so acting as a white knight to fend off a hostile rival bid from Merck, also engaged in some vigorous buying of Schering s shares. The tactics of both firms took watc fuel dispenser hers of Germany s normally phlegmatic pharmaceuticals sector by surprise. See article Mirant, a power generator, withdrew its nearly $8 billion bid to buy NRG Energy. The offer had been promptly rejected by NRG when it was made in late May, but since then some of Mirant s larger investors, including Pirate Capital, a hedge fund, had also voiced strong opposition to the deal. A trade commission in the United States is to investigate whether Apple Computer s iPod infringes a patent held by Creative Technology, which makes a rival music-player. The news comes shortly after three Nordic countries said they would investigate co fuel dispenser mplaints that the pricing policy of Apple s iTunes online music store is anti-competitive. LG.Philips, the world s biggest maker of large LCD panels, saw its share price fall by 13% on June 13th after it cut its earnings forecast by half for the quarter. Its profits, like those of other flat-panel manufacturers, are being hurt by a sharp decline in the price of big-screen TVs, but the company also said that sales in the run-up to the World Cup were much lower than expected. More concern from economists that China s economy is overheating. Despite official efforts to cool expansion, industrial production rose by 17.9% in the year fuel dispenser to May. Meanwhile, China s central bank reported rapid growth in money supply and told banks to “pay close attention�to the risks of lending too much. All come tumbling down Stockmarkets around the world fell, primarily over concerns about inflation in America, which increased more sharply than expected in May, and more uncertainty over interest-rate rises. Asian stockmarkets saw some of the biggest losses, as investors worried about the effect of a potential slowdown on exports. As nervousness spread,
