ABSTRACT:
A moisture indicating apparatus for indicating the presence of moisture in a vapor flow confined within a conduit. Sonic energy generated within the conduit is detected at predetermined locations along the conduit by non-intrusively mounted detection devices. The sonic energy is converted into an electrical signal and the magnitude of the electrical signal from each detection device and the time difference therebetween are compared to predetermined magnitude and time-difference standards. If the electrical signals indicate the presence of moisture, responsive action is initiated by a suitable control arrangement connected to the apparatus. In addition to indicating moisture presence, the quality of moisture with the vapor flow is detectable.
