How to Check the Remaining Fuel Level in the Tank?
2 Answers
The method to check the remaining fuel level is to locate the pointer on the right side of the dashboard, which is the fuel gauge. It is marked with 'e' and 'f'. When the pointer is close to 'f', it indicates sufficient fuel, while approaching 'e' means low fuel level. When the pointer reaches 'e', the fuel warning light will illuminate, reminding the driver to refuel. The fuel gauge consists of a voltage-stabilized fuel level indicator and a fuel level height sensor. The working principle of the fuel gauge involves current flowing from the sender through a resistor, which is wound around a bimetallic strip. The bimetallic strip is connected to the pointer of the fuel gauge via a linkage. As the resistance increases, the current through the heating coil decreases, causing the bimetallic strip to cool down. As the strip cools, it straightens, moving the fuel gauge pointer from 'full' towards 'empty'.
Every day when I commute by car, I check the remaining fuel level by looking at the fuel gauge on the dashboard. It usually has a small bar or needle indicating the scale from 'full' to 'empty'. If the car has a digital display, it might directly show a percentage or the remaining kilometers, which is straightforward. After starting the car, the reading becomes more accurate, so I take a quick glance to get an idea. Don’t wait until the warning light comes on to refuel—that means the fuel is too low and could lead to a breakdown. I make it a habit to refill when the tank is half empty, which is both convenient and safe. Some older models may only have a basic gauge, while newer cars with smart features allow you to adjust the display via steering wheel buttons to see the estimated range. Remember to check the sensors during maintenance to avoid inaccurate readings. For long trips, I always estimate the fuel consumption in advance to avoid rushing to find a gas station on the road, saving both hassle and time.
