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 H fuel dispenser ydraulic 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 pist fuel dispenser on 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) (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 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 fuel dispenser 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.

trictions, with the government resuming control of food distribution. Tensions between America and South Korea over how best to tackle the North Korea problem were not dispelled when the two inaugurated a high-level strategic dialogue last month. Frustrations on all sides at the diffi fuel dispenser culty of dealing with prickly North Korea are real. But the other countries round the table have their differences too. Mr Kim will work to widen any splits he can find. Thailand Thaksin s yellow peril Feb 9th 2006 From The Econom fuel dispenser ist print edition But the prime minister s not finished yet AFP THE biggest protest Bangkok has seen in years—perhaps since the huge demonstrations of 1992 that led to the restoration of democracy in Thailand—gathered outside the royal palace on February 4th, to demand the resignation of the prime minister, Thaksin Shinawatra. The organisers encouraged protesters to wear or carry something yellow, a colour with royal and Buddhist connotations but also a deliberate echo of the “colour revolutions�?in Ukraine and elsewhere. They put the crowd at 100,000, others perhaps half that number. The chief organiser, Sondhi Limthongkul, a media tycoon who has turned from friend to foe of Mr Thaksin, promises another massive show of popular discontent People, not power outside the palace this weekend. The prime minister failed to make him move it somewhere less prominent. There have been rumblings of dissent in government circles two cabinet ministers and the head of the state electricity-generating firm have resigned in recent days. Mr Thaksin s opponents hop fuel dispenser e disgruntled legislators from the ruling Thai Rak Thai party will break away and support planned no-confidence or censure motions in parliament. They are also seeking impeachment proceedings, and have petitioned King Bhumibol to order the prime minister to quit or call elections. Mr Thaksin had hoped his family
