Get to Know the Fuel Quantity Indicator

The indicator for a resistive fuel quantity system is typically a very simple instrument consisting mainly of a meter movement housed within a standard 3-1/8” case. On occasion the indicator may have some signal conditioning element within it, however that is quite rare and when it does occur even that will be a very simple voltage divider or a single stage amplifier.
