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 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 model. 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.) t fuel dispenser o minimum flow (Q min.) is 10 to 1. as fuel dispenser leave factory. The ra fuel dispenser tio 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.

an ex-prime and foreign minister still thought to wield influence, says its historically good relations with the Palestinians, Syrians and others give Russia “special opportunities�in the Middle East. Mr Primakov says he is sure the Hamas initiative was quietly agreed with America and other parties, even though they squawked in public. Actually, says that American official, “we were very, very unhappy.�The decision to fund the Hamas-led PA has taken Russia even further from the previously agreed line. The Hamas poll win—a “great blow�to American policy, crowed Mr Putin—seems to have created a perfect, if temporary, match. As Avinoam Idan, formerly an Israeli diplomat in Moscow, puts it, Hamas was looking for recognition; the Kremlin was looking for a chance to demonstrate its independence. And rather than the considered wiliness for which Mr Primakov was once renowned, the Hamas invitation announced by Mr Putin looks like evidence of a different trend the Kremlin s tightening grip on policymaking. Americans say that Russia s foreign ministry was as surprised by the move as they were. Divining who in the Kremlin has the president s ear is tricky; but among them, says Mr Mirsky, are some who are schooled to befriend “any thug in the world who declared himself anti-American� There are some, says Mr Simes, who feel Mr Putin and his predecessor, Boris Yeltsin, were too obliging to America over Kosovo, Iraq and America s inc fuel dispenser ursions in Central Asia. Many top officials regard America s promotion of fuel dispenser pro-western forces in the former Soviet states as a provocation, and the stalling of Russian efforts to join the World Trade Organisation as deliberate American sabotage. Russians become doubly suspicious when they see signs of a link, however tenuous, between America s cultivation of new friends in the ex-Soviet world, and its broader Middle East policy� take, for example, the fact that Georgia recently raised its contribution to the American-led coalition in Iraq. � fuel dispenser
