1. General survey about [url=http://www.sankichina.com]Fuel Dispenser[/url]’s designation

1. [url=http://www.sankichina.com]Fuel Dispenser[/url]

      The full name is [url=http://www.sankichina.com]Fuel Dispenser[/url] for motor vehicles, used for measuring fuel of vehicles. It consists of meter for volumes of liquids, additional devices, and ancillary devices.
2. Liquid-volume meter

      Liquid-volume meter is a meter measuring liquid volume accumulatively, which consists of measurement transducer, calculator and indicator devices.
When measuring liquid flow past the measured transducer, its mechanical measuring components divide flowing liquid into volume unit, then flow out together. At the same time it transforms the volume unit into relative position change value, indicating the total flowing volume by calculator and indicator devices. Measurement transducer once is called meter, which is the key parts in flow meter.
3. Additional devices

      Additional devices are apparatus aiming at ensure the accuracy of [url=http://www.sankichina.com]Fuel Dispenser[/url], such as pump, oil-air separator, nozzle, solenoid valve, filter, oil indicator, pipeline, etc.
4. Ancillary devices

2. [url=http://www.sankichina.com]Fuel Dispenser[/url]’s development history

      Ancillary devices are adapted to realize other special functions of [url=http://www.sankichina.com]Fuel Dispenser[/url], such as payment indicator, pre-setting, oil-air recovery, taxation interface, IC card read, amount indicator, zero-clear, etc.[url=http://www.sankichina.com]Fuel Dispenser[/url] is created and developed along with the development of automotive industry, petrol industry, and transportation industry.
The first [url=http://www.sankichina.com]Fuel Dispenser[/url] in world, manufactured in the early of 20 century, is made of manual suction pump, transparent cylinder with scales, and switch (see the 1-1 diagram). The certain volume fuels flow into the vehicle’s tank by means of gravity, controlled by switch. The paid volume is decided by the operator eye-measuring the scales. Manual pump is replaced by motor pump until in 1920s, and the transparent cylinder by flow meter with scales. In 1940s, indicative handle calculator developed as wheel calculator, function having changed from indicator volume only into measuring volume, money, and unit price adjustment as well.
       The development of electronic technique in the 1970s promotes the evolution of indicator operation and control management of [url=http://www.sankichina.com]Fuel Dispenser[/url]. The end of 20th century witnesses rapidly development of [url=http://www.sankichina.com]Fuel Dispenser[/url] and relevant system, such as various electronic display mode, presetting refueling devices, hanged [url=http://www.sankichina.com]Fuel Dispenser[/url] system without island, submersible pump filling system, [url=http://www.sankichina.com]Fuel Dispenser[/url] mounted vapor recovery devices, multi-nozzles [url=http://www.sankichina.com]Fuel Dispenser[/url], changeable oil label dispenser, and [url=http://www.sankichina.com]Fuel Dispenser[/url] installed IC card. Meanwhile , some techniques correlative filling station management were developed consequently, including the Centre manager controlling multi-dispensers, monitor system for storage tank, station’s payment, safety alarm and services system, network transmission technique among relative departments, inter-station, and internal station, as well as customer self-operate refueling station system—no staff filling station.
