Bulus özellikle, yakit deposunda bulunan yakit ölçümünün, samandira kullanilmadan yapilmasini saglayan yakit deposu seviye sistemi ile ilgilidir. Teknigin Bilinen Durumunun Açiklanmasi Araçlarda, kamyonlarda yakit deposu seviyesinin ölçüldügü samandira sistemleri kullanilir. Yakit miktarinin sürücü tarafindan bilinmesi önemlidir. Uzun sürüslerde yanlis yakit seviyesi yolda kalinmasina neden olabilmektedir. Ayrica yakit tankinda tüm yakitin bitmesi durumunda tank dibindeki partiküller samandira sistemine zara vererek zamanla bozulmasina neden olabilmektedir. Ayrica yakit alinirken alinan miktar kadar depoda yakit olup olmadigi kontrol edilememektedir. Eksik veya fazla yakit verildiginin kontrolü mümkün olamamaktadir. Ayrica, bir yakit kaçagi veya yakit hirsizligi durumunda bunun fark edilmesi zor olmaktadir. Araçlarda yakit depolarinin içerisinde yakit samandirasi bulunur. Yakitin miktarini belirlenmesi samandira sistemi ile saglanir. Sistem mekanik olarak çalismaktadir. Samandira mekanik hareketten aldigi degeri elektriksel olarak degistirerek kombi göstergeye gönderir ve sürücü yakit miktarini görür. Bu sistemde mekanik oldugu için zamanla parça hasarlanmalari yasanir, yakit ölçümü için kullanilan samandira bidonu delinerek ölçümü yanlis göstermesine neden olabilmektedir. Mekanik samandira sisteminin kullanilmadigi ve yakit istasyonlarinda kaç litre yakit aldiginin sürücü tarafindan yakit sisteminden bilindigi, eksik veya fazla yakit verilirse farkinda olmasinin saglandigi yeni teknik gelistirmelere ihtiyaç duyulmaktadir.

TR TR TR TR TR TR TR TRDESCRIPTION FUEL TANK LEVEL Technical Field The present invention relates to fuel tank level systems in vehicles and trucks. Specifically, the invention relates to a fuel tank level system that allows the fuel level in the fuel tank to be measured without the use of a float. Description of the State of the Art: Float systems are used in vehicles and trucks to measure the fuel tank level. It is important for the driver to know the fuel level. Inaccurate fuel level can lead to stranded driving on long drives. Furthermore, if the fuel tank is completely empty, particles at the bottom of the tank can damage the float system, causing it to deteriorate over time. Furthermore, when refueling, it is impossible to verify whether the tank contains the same amount of fuel as before. It is impossible to verify whether too little or too much fuel has been dispensed. Furthermore, it is difficult to detect a fuel leak or fuel theft. Vehicles have fuel floats inside their fuel tanks. Fuel level determination is achieved through a float system. The system operates mechanically. The float converts the value obtained from the mechanical movement into electrical data and transmits it to the instrument cluster, allowing the driver to see the fuel level. Because this system is mechanical, parts can become damaged over time, and the float canister used for fuel measurement can become punctured, causing inaccurate readings. New technical developments are needed that eliminate the use of a mechanical float system and allow drivers to know the number of liters of fuel they have consumed at fuel stations from the fuel system, ensuring they are aware of any inadequate or excessive fuel levels. Application TR 2017/19844 describes a fuel tank level control and anti-sloshing system. The parallel-positioned level control plate, the float containing the level-detection arm that moves along the channel as the level control plate moves up and down, and the support element that acts as a guide and increases the strength of the fuel tank are described. However, the system uses a float, and the system using a level control plate is discussed. A new fuel level system is needed that can determine the number of liters of fuel consumed and fuel leaks without the use of a float. Consequently, the development of new fuel tank level systems that do not require a mechanical float system is becoming necessary. Explanation of the Invention's Purposes: Based on the state of the art, the invention aims to develop a fuel tank leveling system that eliminates the drawbacks of existing structures and allows fuel level measurement in the fuel tank without the use of a float. Another purpose of the invention is to enable drivers to be aware of how many liters of fuel they have purchased at fuel stations without the use of a mechanical float, and to be aware of any intentional under- or over-fueling. Another purpose of the invention is to develop a fuel tank leveling system that allows drivers to detect a fuel leak or theft. Another purpose of the invention is to develop a fuel tank leveling system that allows drivers to detect how many liters of fuel have been purchased at a fuel station and whether the amount is insufficient or excessive. Another aim of the invention is to develop a fuel tank level system that allows the driver to see the fuel level accurately from the indicator without using a buoy mechanical system. In order to achieve the aforementioned objectives, a fuel tank level system that provides significant technical advantages has been developed. Explanation of the Figures Figure-1 is a drawing of a representative application of the invention.
