All aircraft fuel sensors must have some form of fuel quantity indicator. These devices vary widely depending on the complexity of the fuel system and the aircraft on which they are installed.
Simple indicators requiring no electrical power were the earliest type of quantity indicators and are still in use today.
The use of these direct reading indicators is possible only on light aircraft in which the fuel tanks are in close proximity to the cockpit. Other light aircraft and larger aircraft require electric indicators or electronic capacitance type indicators.
A sight glass is a clear glass or plastic tube open to the fuel tank that fills with fuel to the same level as the fuel in the tank. It can be calibrated in gallons or fractions of a full tank that can be read by the pilot.
Another type of sight gauge makes use of a float with an indicating rod attached to it. As the float moves up and down with the fuel level in the tank, the portion of the rod that extends through the fuel cap indicates the quantity of fuel in the tank.
More sophisticated mechanical fuel quantity gauges are common. A float that follows the fuel level remains the primary sensing element, but a mechanical linkage is connected to move a pointer across the dial face of an instrument.

Honeywell Launches Disruptive Research on Hydrogen Fuel Cells for Aircraft A consortium led by Honeywell met recently to launch a European Clean Aviation project that will develop a new generation of hydrogen fuel cells for the aviation industry.
Project NEWBORN will involve multidisciplinary collaboration between 18 partners from 10 European countries to develop an aerospace-qualified megawatt-class fuel cell propulsion system powered by hydrogen.
Green hydrogen, the term given to hydrogen produced by splitting water into hydrogen and oxygen using renewable electricity, is an extremely clean power source that can be used to propel future aircraft, which makes it appealing as the aerospace sector works to reduce carbon emissions.
The megawatt-class fuel cell propulsion system delivered by NEWBORN will give birth to future, sustainable aviation beyond a megawatt. The final demonstrator will be integrated and tested by Pipistrel Vertical Solutions, a Slovene-based disruptive general aviation manufacturer.
