ine bad effects of accuracy. 2. Pipeline noise Noise and tremble are not generated by pipe itself but hydraulic shock, pipe resonance and pressure pulse. Here explain, combining operation and maintenance of fuel dispense, these reason for noise and tremble 2.1 Hydraulic collision Hydraulic collision refers to the phenomenon in which oil pressure in pipeline is increased quickly as pipe switch open or close or liquid changing flow direction. Hydraulic collision could lead to pipeline noise, which are result from piston changing direction of measurement transducer and witching on or off pipe valve. Δρ= 12lv11+EoE·dδ (v2=0,t≤T) (2-10) Δρ= 12lv11+EoE·dδ ·Tt (v2=0,t≤T) (2-11) Δρ= 12lv11+EoE·dδ ( partial v2�?,t≤T) fuel disp fuel dispenser enser (2-12) Δρ= 12lv11+EoE·dδ ·Tt (partial v2�?,t≤T) (2-13) In above formulae: Δρ── increasing pressure value; υ1── previous velocity of flow υ2── latter velocity of flow T ── time that start from collision to reflect T=2la T ── changing time of velocity of flow fromυtoυ2 E0 ── elastic volume of fluid cubage E ── elastic modulus of pipeline d ── inner diameter of pipe fuel dispenser δ── pipe thickness l ── diffused distance of shock wave a ── diffused speed of shock wave The above formulae illustrate four kinds of stock pressure on pipe in corresponding operations in which switching on or off nozzle quickly or slowly. They also explain that slowly switch on and off nozzle generating less collision pressure than that of rapidly under a certain parameter of pipeline system of fuel dispenser. Similarly, it is applicable to stock noise. Therefore, user shall slowly turn on and off nozzle in operation so as to reduce hydraulic stock and noise, and prolong fuel life service of fuel dispenser. Most of manufacturers of fuel dispensers have mounted anti hydraulic stock device in hydraulic system in order to abate the effects to fuel dispensers.

awaited consolidation, in which four or five big players come to dominate the entire European energy utility market. Since E.ON was created in 2000 through the merger of Veba and Viag, two German energy firms, the group has hoovered up companies big and small. It bought Britain s Powergen in 2002 and Ruhrgas, Germany s leading gas company, the year after that, as well as a host of smaller companies in northern and central Europe. After talks with Scottish Power broke down last November because the British energy group rejected E.ON s takeover offer, Wulf Bernotat, boss of E.ON, started to plot his big coup a takeover of Endesa, which would make E.ON the world s largest electricity and gas firm, with more than 50m customers in more than 30 countries. He approached fuel disp fuel dispenser enser Endesa for the first time on December 1st. Mr Bernotat s all-cash offer for Endesa is bigger and better than an earlier ¬21 billion cash-and-shares offer by Gas Natural, another Spanish utility. E.ON can afford such a splash. On the day of the bid s launch the firm reported a 71% jump in net profit from ¬4.3 billion to ¬7.4 billion. Yet Endesa s bosses reacted coolly to their German suitor they think their compan fuel dispenser y is worth more. The Spanish government is even less happy about a bid it sees as unwelcome. It had backed Gas Natural s offer, despite its rejection by Spanish antitrust authorities, in the hope of creating a national energy champion. Mr Bernotat knows that he is stepping into a political hornets nest, involving bitter political and regional rivalries within Spain. “We don t want to get involved in politics and we expect market rules to be applied,�?he says. The Spanish government could use its shares in Endesa to block the German bid. But it will probably refrain. Spain would lose many friends within Europe by acting that way, at a time when Spanish companies are launching big cross-border raids, such as the bid by Ferrovial, a Spanish construction company, to buy BAA, owner of Heathrow, Europe s busiest airp
