erally is mounted centrifugal pump installed in tank. The inlet pressure of fuel dispenser with submersible pump is higher than atmospheric pressure. Submersible pump consists of pump, connecting pipeline and controller. The appearance of submersible pump and its position in tank is showed in diagram 2-10. Diagram 2-10: Submersible pump position and figure Submersible pump is composed of motor and centrifugal pump. Pump motor includes electromotor, wiring panel, overheat protector and pipeline; centrifugal pump has the elements of filter, anti-static subassembly, impeller and pump axis. Diagram 2-11: Main structure of submersible pump Connecting pipeline has two types of fixed and stretched. The former type consists of oil pipe, vapor-recovery pipe, lead pipe and wire. The later type is formed by oil pipe, vapor-recovery pipe, adjusting nut, lead pipe and motor wire. Controller is divided as two parts, upper and lower. Upper part have these components junction box, electric bridge, capacitor, exhausting plug, check valve, pressure adjustor, testing interface of exhaustion and pressure, leakage monitor of pipe. However, lower part is constituted by pipe jointer, lead terminals, pump holder, etc. By function, submersible pump is classified as four categories, namely, standard type, enhanced type, changing-frequency type fuel dispenser and large flow type. The standard type access to general requirements, but the enhanced type not only increase flux than standard type, but also available to mix liquid of gasoline with alcohol. The changing- frequency submersible pump adopt pipe pressure to judge flux. Given a situation in inefficient flux and low pressure the electric frequency of motor would tune high through computer, so as to e fuel dispenser levate rotate speed and increase flux. Contrarily, to reduce electric frequency and rotate speed as pipe pressure being low, adjusting appropriate flowage. The large flow type is adapted in filing station in where needs quickly operation. Some submersible pump has the flow speed of more fuel dispenser

of a POS transaction and is an implicit way to link these message pairs belonging to the same　　 transaction. This linking becomes explicit with the adding of the Split flag for split tenders.　　IFSF POSEPS ImplementationGuidelines - Revision - 20060510　　 10052006 Page 73 of 105　　 Confidential　　 b. The TerminalID TerminalBatch STAN and optionally TimeStamp fields in the OriginalTransaction　　 structure which identify a previous successful payment or loyalty transaction.　　 c.
