The CANTY Molten Glass Level system consists of a high temperature surveillance camera, mounted to view the surface of the molten glass through an opening in the wall. On the wall directly opposite the camera, a reference point is created, often by simply removing a brick from the wall, or boring a hole though it. The position of the reflection of this reference point on the surface of the glass relative to the fixed mount camera, is directly related to the molten glass level. CantyVision™ software is configured to track the position of this reflection with accuracy to 0.001” (0.025mm). A cross-hair is displayed on the operator screen image at all times, to allow the user to visually verify what point is begin tracked by the software. Control outputs are available to the DCS via OPC, 4-20mA and Modbus TCP/IP.
