    Abstract: A system for measuring a fuel-oxidant equivalence ratio includes at least one wall defining a gas volume including fuel and air. A gas ionization source is configured to cause a formation of ions in the gas. A power supply is configured to output a time-varying voltage. A first electrode is disposed in the gas volume, operatively coupled to the power supply, and configured to carry the time-varying voltage. A second electrode is arranged to operatively couple to a signal output by the first electrode after the signal passes through the gas volume. Characteristics of the received signal indicate the fuel-oxidant equivalence ratio.
