1. A method for measuring gas flow in a meter, comprising:

  • directing gas through the meter at various flow rates;

    detecting a gas flow of the gas with a first sensor when the gas is directed at a low flow rate;

    detecting an oscillation frequency of the gas with a second sensor when the gas is directed at a rate to produce an oscillating fluid jet of gas; and

    determining a flow rate based on outputs of at least one of the first sensor and the second sensor.
