Capacitance-Type Fuel Quantity Indicator: Measurement of Fuel Quantity by Weight
Since the indication of fuel quantity can be affected by a change of fuel volume when
subjected to temperature variation, the fuel mass, which cannot be changed by external factors,
can provide a more accurate indication of fuel quantity.
However, it is quite easy to perform such task by relate the density to the relative permittivity
(K), and re-calibrate the indicator.
