<p>An apparatus for detecting the condition of the flow of liquid metal in or from a teeming vessel includes a sensor for detecting vibration caused by a flow of liquid metal in or from the teeming vessel and for outputting a sensor signal corresponding to an amount of vibration detected by the sensor. A signal processor receives the sensor signal and compares the sensor signal to a reference signal and outputs a comparison signal. A logic unit receives the comparison signal and outputs a status signal indicative of the condition of the flow of the liquid metal in or from the teeming vessel.</p> |
