Abrégé
(EN)
PURPOSE: A fuel level detection instrument of vehicle is provided to improve the accuracy of the gas fuel level. CONSTITUTION: A fuel level detection instrument of vehicle comprises a pressure regulator. The pressure regulator includes a fuel shut-off valve(31) which supplies the fuel of the fuel tank to be the fuel distribution, a fuel pressure sensor(33) measuring FPS of the fuel line, a fuel temperature sensor(35) measuring the temperature of fuel of the fuel line, a regulator(32) reducing FPS of the fuel line to the set critical value, a control device(60) which calculates and indicates the gas fuel level. ©KIPO 2009
