How to Read the Car Fuel Gauge?

[DiVincent]

Here are the methods to read the car fuel gauge: 1. The pointer-type fuel gauge indicates the amount of fuel through the position of the pointer. The gauge is marked with two letters, E and F, where F stands for full and E for empty. 2. The digital-type fuel gauge shows the remaining fuel through the number of illuminated bars. More illuminated bars indicate sufficient fuel, while only 1 to 2 bars mean the fuel level is low and needs to be replenished promptly. Below is how the fuel gauge works: Generally, there is a fuel pump in the fuel tank. The computer controls the extraction of fuel and transports it to the engine. A float is installed on this fuel pump, which is connected to a sliding resistor. As the float moves up and down in the gasoline, the change in liquid level alters the resistance, sending different electrical signals to the engine computer.
