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 regulativ fuel dispenser e 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 s fuel dispenser ingularly 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.) to minimum flow (Q min.) is 10 to 1. as fuel dispenser leave factory. The ratio should not be less than 5: 1 in inspecting at operation locale. All of exceeded tolerance fuel dispenser 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.

roduction shot up a staggering 77m tonnes last year, but Mr Mittal reckons “with the combined force, we will be able to accelerate our presence in Asia.� Whether the deal succeeds or not may take months to become clear. Arcelor s board immediately rejected the offer. And Mr Dollé has had some success in stoking the political reaction in Europe. But Mr Mittal is confident. After a meeting with French officials, he insisted that “they have not shut the door, in fact they are looking to open a window.�He roundly rejected the idea that his firm lacks Arcelor s “European� fuel dispenser values “We are European,�he insists, pointing to Mittal Steel s London headquarters and Rotterdam tax registration. He has offered to move the firm s head office to Luxembourg. He also vows that there will be no jo fuel dispenser b losses at Arcelor “as a result of this merger� He thinks the deal can be finalised by June. Arcelor may try some sort of “poison pill�to ward off Mittal. One option is a tie-up with another big steel firm (Mr Dollé was due to meet the boss of Japan s Nippon Steel this week), to ward off this unwelcome advance. If Arcelor tries some such manoeuvre, Mr Mittal might sweeten his offer in weeks to come. Mr Dollé is also trying to make corporate governance an issue, denouncing his rival s plans to retain family control over the combined firm. This looks to be the biggest chink in Mr Mittal s armour. When pressed about the wisdom of installing his 30-year-old son as president and chief financial officer, the steelman appeared to jib. His son Aditya “earned�his position, Mr Mittal insisted, and is “a genius� Pe fuel dispenser rhaps. But the appearance of nepotism will not help his cause. Whatever happens with this particular deal, the trend towards global consolidation now seems unstoppable. Roger Agnelli, boss of CVRD, a Brazilian firm that is the world s biggest supplier of iron ore, declares that steel will now become a “game of giants� “Everybody is now in play,�says Dick
