Fuel Gauge Measurements

In this article we ll learn why our fuel gauges behave the way they do.

Fuel gauge measurements.

This measurement determines the length of the sending unit s float arm. The metallic ruler will be wet with fuel from its tip to a certain measurement such as 3 feet. Many large transport aircraft use a different fuel gauge design principle. 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 also ensures that the gauge reads properly. First measure tank depth from the top of the tank near the sending unit to the bottom. Calculate the level of fuel in the tank by dividing the measurement taken on the metallic ruler by the total height of the tank. This type of system can be used to measure the amount of gasoline or some other type of liquid.

A fuel gauge is a device inside of a car or other vehicle that measures the amount of fuel still in the vehicle. The sender which measures the level of fuel in the tank and the gauge which displays that level to the driver. First let s see how a typical sender works.
