Overview of Resistive Type Fuel Qty. Measuring System


The Resistive Type Fuel Quantity measuring system utilizes a variable resistive element in order to vary a precise electrical DC voltage based on the quantity of fuel in the fuel tank. The varying electrical signal, in turn, is used to drive the pointer on a fuel quantity indicator in a manner which is proportional to the amount of fuel in the tank, thereby visibly indicating remaining fuel quantity to the pilot.

The typical components in this type of system include the following:

a) Regulated DC Power Source
b) Tank Unit (Fuel Qty Sender, Fuel Probe)
c)  Indicator
