TR TR DESCRIPTION FUEL TANK LEVEL Technical Field Present invention; It is related to fuel tank level systems in vehicles and trucks. The invention is especially related to the fuel tank level system, which allows fuel measurement in the fuel tank to be made without using a float. Description of the State of the Art Buoy systems are used in vehicles and trucks to measure the fuel tank level. It is important for the driver to know the amount of fuel. On long drives, the wrong fuel level may cause stranding on the road. Additionally, if all the fuel in the fuel tank runs out, the particles at the bottom of the tank may damage the float system and cause it to deteriorate over time. Additionally, when purchasing fuel, it is not possible to check whether there is enough fuel in the tank to match the amount purchased. It is not possible to control whether too much or too little fuel is given. Additionally, in case of a fuel leak or fuel theft, it is difficult to detect. There are fuel floats inside the fuel tanks of vehicles. Determination of the amount of fuel is provided by the float system. The system works mechanically. The buoy electrically changes the value it receives from the mechanical movement and sends it to the combi display, and the driver sees the fuel amount. Since this system is mechanical, parts may become damaged over time, and the float canister used for fuel measurement may be punctured, causing the measurement to be displayed incorrectly. There is a need for new technical developments where the mechanical float system is not used and the driver knows how many liters of fuel he has received at the fuel stations from the fuel system and is aware of whether he is given too much or too little fuel. In the application numbered TR 2017/19844, the fuel tank level control and turbulence prevention system is explained. The parallel positioned level control plate, the float containing the level detection arm that determines the fuel level by moving on the channel while the level control plate moves up and down, and the support element that acts as a guide by providing the up and down movement of the level control plate and increases the strength of the fuel tank are explained. However, it is a system using a float and a system using a level control plate is mentioned. A new fuel level system is needed, which can tell how many liters of fuel the driver has consumed and fuel leaks without using a float. In conclusion; It becomes necessary to develop new fuel tank level systems created without a mechanical float system. Explanation of the Purposes of the Invention Based on the known state of the technique, the purpose of the invention is to develop a fuel tank level system that eliminates the drawbacks in existing structures and allows fuel measurement in the fuel tank to be carried out without using a float. Another purpose of the invention is to ensure that the driver is aware of insufficient or excess fuel without using a mechanical float and by knowing how many liters of fuel he has purchased at fuel stations. Another purpose of the invention is to develop a fuel tank level system that allows the driver to notice this in case of a fuel leak or fuel theft. Another purpose of the invention is to develop a fuel tank level system that allows the driver to detect how many liters of fuel are purchased from the fuel station and whether the fuel consumed is insufficient or excessive. Another purpose of the invention is to develop a fuel tank level system in which the driver can accurately see the fuel level from the indicator without using a float mechanical system. In order to achieve the mentioned objectives, a fuel tank level system that provides significant technical advantages has been developed. Explanation of Figures Figure-1; It is a drawing of a representative application of the invention.
