1. A method of indicating the presence of liquid moisture in an airflow, comprising:

  • sensing mass flow rate data of an airflow;

    sensing a first heat removed from a first heated temperature sensor, the first heat removed including heat removed by the airflow from which liquid moisture has not been removed;

    coupling the sensed mass flow rate data and the first sensed heat removed to a computer; and

    computing in the computer, as a function of the mass flow rate data and the first sensed heat removed, the presence of liquid moisture in the airflow.
