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 a fuel dispenser nd 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+Eo fuel dispenser E·dδ ( partial v2�?,t≤T) (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 δ── pipe thickness l ── diffused distance of shock wave a ── diffused speed of shock wave The above formulae illustrate four kinds of stoc fuel dispenser k 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.

Though a　　mechanism exists for unlocking transactions in this situation it is not possible for other　　Controller Devices or the device to determine if the fuel dispenser Controller Device that locked the　　transaction has failed. The following method should be used to determine if a Controller　　Device is off-line.　　If a Heartbeat is not received within 3 Heartbeat Intervals from the Controller Device that　　locked the transaction the device should unlock the transaction locked by that Controller　　Device.　　The Heartbeat Interval for Controller Devices should be set to the default value (10 seconds)　　and not changed.　　In practical terms this means if the device does not receive a Heartbeat from the Controller　　Device that locked the transaction in 30 seconds then the device

nment does. If it accepts the three benchmarks and releases Gilad Shalit the soldier captured in June by Palestinian militants that will be a very positive step.�? But could Hamas make thi fuel dispenser s concession? Its stubborn line has, up to now, played well to Palestinian suspicions of Israel s intentions. “To date, Israel has not recognised the 1967 lines as its legal border,�? Ahmad Yousuf, a Hamas spokesman, told an Israeli newspaper. “When it does so, I will tell you whether we recognise Israel.�?It is a common Palestinian belief that the three Quartet conditions are designed not to encourage Hamas to change its stance, but to provide an excuse never to have to deal with it. Indeed, for Palestinians, the main purpose of a unity governm fuel dispenser ent has always been to reduce the factional infighting that has rendered the West Bank and Gaza ungovernable, rather than as a sop to Israeli demands. Conversely, among Israeli Jews, the distrust of Hamas is almost universal. Even Zehava Gal-On, arguably Israel s most left-wing Jewish parliamentarian, says she would find it very hard to talk to the group, though she acknowledges that it will eventually become inevitable. Yet both the Palestinian and the Israeli leaderships are under growing pressure to find a new course. Hamas has been facing massive strikes by PA workers, in despair after mo fuel dispenser nths without wages; the al- Najah poll gave Fatah nearly twice as many votes as Hamas if a new parliamentary election were held. The Israeli government led by Ehud Olmert is scrabbling for a toe-hold after the failure of its campaign against Hizbullah in Lebanon. Even before that war, Mr Olmert had said he would negotiate with a Hamas-led government if it accepted the Quartet s conditions. The day after the Palestinian unity government was announced an Israeli military court ordered the release of 18 Hamas legislators and ministers arrested in recent weeks. That could become the first step in an exchange of Palestinian prisoners for Corporal Shalit. Both Israel
