China Hongyang Group, is an integrated enterprise with the research & development, production and marketing of Fuel Dispenser and related accessories as well as service station concerning equipments. It concentrates on the relative manufacture & services of filling station such as Hongyang tax control Fuel dispenser, IC Card fuel dispenser, manage system of network for stations, submerge pump and liquid level devise. China Hongyang Group, designed supplier of SinoPec and PetrolChina, our HONGYANG products have been sold to over 50 countries in South-east Asia, Mid-east, Africa, Europe and well received in their markets.

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 rega fuel dispenser rded 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 main introduce the double-nozzle fuel dispenser. Measuring main board is the core in fuel dispenser’s electric control system, which is reason why some fuel dispenser 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 fuel dispenser 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

be real-time automatic dubbing, which will let people watch foreign films or television programmes in their native languages, and search engines that will enable users to trawl through multilingual archives of documents, videos and audio files. And, eventually, there may even be e fuel dispenser lectronic devices that work like Babel fish, whispering translations in your ear as someone speaks to you in a foreign tongue. This may sound fanciful, but already a system has been developed that can translate speeches or lectures from one language into another, in real time and regardless of the subject matter. The system required no programming of grammatical rules or syntax. Instead it was given a vast number of speeches, and their accurate translations (performed by humans) into a second language, fuel dispenser for statistical analysis. One of the reasons it works so well is that these speeches came from the United Nations and the European Parliament, where a broad range of topics are discussed. “The linguistic knowledge is automatically extracted from these huge data resources,�says Dr Waibel. Statistical translation encompasses a range of techniques, but what they all have in fuel dispenser “Most of the time, common is the use of statistical analysis, rather than rigid rules, to convert text from the languages that one language into another. Most systems start with a large bilingual corpus of text. By translation analysing the frequency with which clusters of words appear in close proximity in the researchers deal two languages, it is possible to work out which words correspond to each other in the
