Fuel Gauge Measurements

Many large transport aircraft use a different fuel gauge design principle.

Fuel gauge measurements.

This type of system can be used to measure the amount of gasoline or some other type of liquid. In this article we ll learn why our fuel gauges behave the way they do. Calculate the level of fuel in the tank by dividing the measurement taken on the metallic ruler by the total height of the tank. A fuel gauge is a device inside of a car or other vehicle that measures the amount of fuel still in the vehicle.

The length of the sender arm may have to be modified to fit the dimensions of your fuel tank. Systems that measure large fuel tanks including underground storage tanks may use the same electro mechanical principle or may make use of a pressure sensor sometimes connected to a mercury manometer. This measurement determines the length of the sending unit s float arm. First let s see how a typical sender works.

This also ensures that the gauge reads properly. The sender which measures the level of fuel in the tank and the gauge which displays that level to the driver. There are two main parts to a fuel gauge.
