Abstract
An apparatus and method for detecting the condition of the flow of liquid metal in or from a teeming vessel includes one or more sensors for detecting vibration caused by a flow of liquid metal in or from the teeming vessel and for outputting a sensor signal corresponding to mechanical and acoustic vibrations detected by the sensor. A signal processor receives the sensor signal and compares the sensor signal to a reference calibration 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 which can be used to stop the flow of metal. The calibration signal can be static or may be dynamically updated.
