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) (2-12) Δρ= 12lv11+EoE·dδ ·Tt (partial v2� fuel dispenser ?,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 fuel dispenser 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 prolo fuel dispenser ng 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.

ment. Against that background, the quiet word in the ear was tried at Vodafone and failed, mainly because both board and shareholders were divided. Some investors did speak privately with its chairman, Lord MacLaurin, but got little joy. Lord MacLaurin was on his way out and happy to leave the decisions on Mr Sarin s future to his successor, Sir John Bond, the former head of HSBC who took over this week. Nor were powerful shareholders united. Vodafone s problems are well known—the company announced a £22 billion ($41.2 billion) annual loss in May—but solutions to them are less clear. Institutions such as Legal & General, an insurer that owns 3.7%, argued that it would be unwise to change the chief executive and chairman at the same time. In the event, the rebels failed to carry the day in open confrontation to fuel dispenser o. But then, they had not expected to. “The purpose wasn t to oust Arun Sarin then and there,�?says Anita Skipper of Morley. “The purpose was to say to John Bond that there are concerns. The change in tone and tactics at Vodafone suggests that relations between British companies and their owners may become more testy in coming years. Whether this will lead to better performance remains to be seen. But it bodes ill for the quality of the sandwiches they serve. © 2006 . fuel dispenser  About sponsorship Northern Ireland Rough justice Jul 27th 2006 | BELFAST From The Economist print edition One obstacle to restoring devolved government is crumbling BRITAIN s MPs go on holiday this week with their return-to-work dates in their diaries.
