motor and solenoid valve, with larger power. it also have the type of double-nozzle fuel dispenser mounted with total two sets of system, however, most manufacturers don’t install this type in order to reduce cost. With more than four nozzles, this fuel dispenser is able to be regarded as multi-nozzle type. At recent, most of multi-nozzle fuel dispensers made by domestic manufacturers are rebuilt from double fuel dispenser, which actually mounted two pieces of double fuel dispensers to one frame, in the same way 3 piece to six-nozzle. Therefore, learning the structure of double fuel dispenser is able to know multi-nozzle type. Here ma fuel dispenser in introduce the double-nozzle fuel dispenser. Measuring main fuel dispenser board is the core in fuel dispenser’s electric control system, which is reason why some people called this kind as ‘computer fuel dispenser� These operation including starting or stop, calculation, count, data generation and dialogue with machine also are conducted under the control of measuring main board. Display screen, keyboard and fuel dispenser’s switch are the main interface between operator and machine. The staff’s control command to fuel dispenser is mainly conducted through keyboard and nozzle switch, but report information and data are showed in display screen. The function of flow pulse converter, widely called as sensor, is to convert influx into electric pulse so that measuring main board process data. Motor is momentum of rotation of pump; solenoid valve used for presetting filling; power supply board is resource of electric system, which is used for converting alternative current into stable and clean directive current fuel dispenser needed. 2. Parts structure 2.1 Main board structure Measuring CPU: a core of fuel dispenser, responsible for obtaining operation information ---- lift up or put down nozzle, starting or stopping motor and solenoid valve through control circuit (small flow is open before large flow in starting process, vice versa in stopping process ), collecting fl fuel dispenser

Please note that the 2 pin　　Weidm ller BLZ (or equal) connectors and receptacles are recommended for connecting　　IFSF FTT-10 devices.　　The LON uses a P-Persistence CSMA protocol (similar to Ethernet) and so no master is　　required on the bus.　　The LON chip uses 3 processors and so the communications on the bus (managed by 2 of　　them) never interferes with the transfer of messages with the application (managed by the　　third).　　The forecourt communication expects to use a LON component for layer 1 to 6 using　　Explicit Messages.　　The length of such messages is set by the Max_Block_Length communication data element　　(see chapter 4.5 Communication Service Database). The range for the block length is 32 to　　228. To allow messages longer than this value a Block number BL is included in the　　message (for details see chapter 4.4 Block Cutting).　　2.2 Application Communication Basics　　To avoid fuel dispenser

down and, reflected, feel yourself, as Ms Horn puts it, “falling right into it, encountering a twilight zone, somewhere beyond� The same idea lies behind another haunting piece called “Twilight Transit� In a dark room nine black human skulls on stands, each lit from below by bright lights, are aligned with a round, mobile mirror on one side and a glass disc on the other. As the spectator looks into a mirror behind which sits a skull, the sense of the “beyond� of what lies after life, is distinct and powerful. Despite the seemingly ghoulish material, Ms Horn has clearly embraced a new serenity. She senses, however, that Berli fuel dispenser ners are more interested in her earlier experiments the feathe fuel dispenser rs, receptacles catapulting ink onto walls, the sexier stuff. Berliners, she claims, “do not get or do not want to get�the newer, more memory-tugging installations. She describes her show s final section as “melancholy� the rooms here are, indeed, touching, sombre and dark. Ms Horn feels that this work is for and about a city of such historical sadness. Then, reaching the last room, bathed in unexpected natural light, Ms Horn points through the window to a restored building outside, which used to lie behind the wall. “And there s Berlin,�she says. “Rebecca Horn Drawings, Sculptures, Installations, Films 1964-2006�is at the Martin-Gropius-Bau in Berlin until January 16th.
