Fuel Gauge Measurements

This type of system can be used to measure the amount of gasoline or some other type of liquid.

Fuel gauge measurements.

First let s see how a typical sender works. 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. A fuel gauge is a device inside of a car or other vehicle that measures the amount of fuel still in the vehicle.

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. In this article we ll learn why our fuel gauges behave the way they do. The length of the sender arm may have to be modified to fit the dimensions of your fuel tank.

This measurement is not meaningful however until you compare it to the tank s capacity. 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.
