An apparatus for detecting an anomaly in a flowing stream includes a set of blades rotatably suspended in the flowing stream and aligned with a normal flow direction of the flowing stream. The blades are configured to rotate at one rate when the anomaly is present in the flowing stream and to rotate at a different rate when the anomaly is absent from the flowing stream. A device is prescribed for measuring rate of rotation and rotation direction of the blades.
