    ine bad effects of accu fuel dispenser racy. 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?,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 sp fuel dispenser eed 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 i fuel dispenser n order to abate the effects to fuel dispensers.

    write the recipient ad fuel dispenser dress table  - add one recipient address in the table  - remove one recipient address from the table.  Add_Recipient_Addr and Remove_Recipient_Addr are the only Write Messages that can be  used by devices to update the table safely.  Devices should only add themselves logical devices they are physically hosting.  Implementation Guideline  To enable a site controller to configure the recipient address tables of each node on the  network it must know both the logical and physical addresses of each node. This can only be  done when a heartbeat message has been transmitted from a node since it is only then that the  site controller receives the physical address.  For example consider the case of a site controller (PNA 21 LNA 21) that wants to configure  a dispenser (PNA 11 LNA 11) to send its unsolicited messages to a tank gauge (PNA 91  LNA 91). It cannot do this unless it knows the physical node address of the tank gauge since  the Write Recipient Address Table command only contains a logical address field. Once a  heartbeat command has been received from the tank gauge then its physical address can be  obtained and added to a Physical Address Table within the site controller.  Note also that each su fuel dispenser bnetnode address must be unique within an IFSFLON network.

    lation there. Most of t fuel dispenser hem are ruled by their tribal code, the notable exception being where the rival Islamist code, of the stringent Saudi variety which is preached by the Taliban and quite new to Afghanistan, is strong. Islamism has rivalled Pushtunwali for centuries; it has often gained prominence, as currently, in time of war. More typically, the two competing ways have cross-fertilised in Afghanistan, each subtly influencing the other. Pushtunwali s principles have not changed in centuries—certainly not since they were recorded by Victorian ethnographers, middle-class soldiers and civil servants players of the Great Game. Most lionised the fierce tribesmen, who periodically murdered them. Some even swallowed a delicious Pushtun claim to be descended from a lost tribe of Israel. But not all Westerners fell for the Pushtun. As a reporter for the Daily Telegraph, attached to the Malakand Field Force, Winston Churchill wrote “Their system of ethics, which regards treachery and violence as virtues rather than vices, has produced a code of honour so strange and inconsistent that it is incomprehensible to a logical mind.? Pushtun amateur genealogists (that is, most Pushtun men) say Pushtunwali is 5,000 years old. But as Pushtu was first written less tha fuel dispenser n 500 years ago, the theory is hard to test. The code s sine qua non is honour, or nang, a word which, according to Sir Olaf Caroe, an imperial scholar of the Pushtuns, contains a mythical sense of chastity. According to Khusal Khan Khattak, a great 17th-century Pushtun poet, credited with 45,000 poems “I despise the man who does not guide his life by nang, the very word nang drives me mad!?In dusty Pushtun villages today, few bearded men would not nod approvingly at this. “Any man who loses his honour must be completely ostracised,?said Sandaygul, a long-beard of the Mangal tribe in Afghanistan s south-eastern Paktia province. “No o fuel dispenser ne would congratulate him on the birth of child. No one would marry his daughter. No one w
