Background Technology:

     Flow groove is a functional refractory material used to transport molten aluminum water in aluminum deep processing industry, it has the key role of carrying, guiding, shunting, transportation, classification control, liquid level refers to the liquid level of the liquid medium in the container height, in industrial production, liquid level is a very important parameter, by the liquid level combined with other parameters can be calculated the volume of the liquid medium, quality and other information, In the process of storage and transportation of liquid media, it is also necessary to monitor the liquid level at all times to determine whether there is overflow or leakage and other accidents. The existing technology generally adopts liquid level detection rod to detect the aluminum water quantity in the holding furnace. However, with the increase of process requirements, the temperature of aluminum water needs to reach 900°c, and aluminum water is provided continuously. The flow trough is adopted to flow aluminum water, and the liquid level detection rod is not suitable for detecting the aluminum water in the flow trough. MIDEKER has proposed a laser sensor for aluminum water level measurement.
