What do you think of gac gonow automobile fuel meter?

There are two English letters on the fuel gauge of gac gonow automobile, e stands for out of fuel and f stands for full fuel. There are two coils in the fuel gauge, one on the F side and the other on the E side. The sensor is a variable resistor controlled by the height of the float. The change of resistance determines the strength of the magnetic field lines of the two coils, which also determines the deflection direction of the pointer. Water thermometer and fuel meter are also indicated by indicator lights. The water temperature indicator light indicates that the water temperature is high, and the fuel indicator light indicates that the fuel is near the low point as an auxiliary reminder.

the function of fuel gauge

the fuel gauge is used to indicate the fuel quantity in the fuel tank of an automobile, which can be displayed by a pointer or a number. The fuel gauge consists of a fuel level indicator with a voltage regulator and a fuel level height sensor. The function of the low fuel level alarm device is to give an alarm immediately when the fuel quantity in the fuel tank is less than a specified value to attract the driver's attention.

don't wait for the alarm light to come on before refueling, because the gasoline pump is in the oil tank, and it is cooled and lubricated by gasoline. Too little oil will not be conducive to the normal operation of the oil pump and reduce its service life.

It is not recommended to fill it up when refueling, because gasoline expands when heated and volatilizes into gasoline vapor at high temperature in summer, which requires space to contain it. If there is no space for filling it up too much, gasoline vapor and even liquid gasoline will enter the carbon canister for storage, and the carbon canister will escape into the air when it is full, which not only wastes but also pollutes the environment.
