A method and apparatus for measuring wetness of a gas flow within a conduit is provided that includes a first pressure sensor, a second pressure sensor, a sonar based flowmeter, and a processing device. The first pressure sensor is operable to sense the pressure of the gas flow within the conduit at a first position. The second pressure sensor is operable to sense the pressure of the gas flow within the conduit at a second position. The second position is located downstream of the first position an amount sufficient that the gas flow experiences a pressure drop. The sonar based flowmeter is configured to determine a volumetric flow rate of the gas flow. The processing device is in communication with the first and second pressure sensors and the sonar based flowmeter. The processing device is adapted to determine a difference in the pressure sensed by the first and second pressure sensors, and to determine the wetness of the gas flow using the difference in pressure and the volumetric flow rate.
