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. fuel dispenser 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 v fuel dispenser 2�?,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 fuel dispenser 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.

verywhere; growing concern about eating too much fat and salt; and the industrialisation of the meat industry, whose ersatz sausages and hams can be sold more cheaply than the real thing. Yet the taste remains. Given the simplicity of the ingredients—meat, salt, air and time, with smoke, seasonings and water as optional extras—it is not surprising that the art of salting and curing was perfected in many cultures long before the chemical ratio fuel dispenser nale for it was discovered. Briefly, salting preserves animal proteins by inhibiting microbial growth; it does this by dehydrating both the flesh itself and cells in the moulds and bacteria that feed on it, either ending or drastically slowing their growth, which unchecked would cause the meat to spoil. Salt fuel dispenser can be rubbed into the meat, as advised by Cato, or the meat can be submerged in a brine in which the salt has been dissolved. Brined or pickled meat often has to be cooked or soaked, because wet cures permeate the flesh more thoroughly and the meat would otherwise be too salty to eat. The meat is then hung up to dry, either in fresh air or in smoke, which is itself a complex material made up of hundreds of components, including carcinogens, which inhibit microbial growth; phenolics, which retard fat oxidation; and an array of sugars, acids and particulates that colour and flavour the meat. Unfortunately what is bad for microbes can be harmful to humans too excessive consumption o fuel dispenser f smoked and cured meats has been linked to several types of cancer, though unconscionable amounts would have to be eaten to pose much of a risk. Traditionally, western Europeans smoked meat over alderwood, though oak and beech are becoming more prevalent. North Americans tend to use hickory, mesquite, pecan, apple or cherry. Woods with heavy concentrations of resin, such as pine and fir, are unsuitable for smoking, because the resin tends to flare and produce too much soot and tar. There also is a distinction between hot-smoking, in which meat is, in effect, c
