APPARATUS AND METHOD FOR MOLTEN METAL DEPTH DETECTION
摘要
Apparatus and method for determining when the depth of molten (18) poured into a vessel (12) has reached a selected level. A conduit (22) connected to a source of pressurized gas and having an orifice (43) at its distal end (38) restricts the flow of gas out of the conduit which is positioned at a selected level in the vessel. A drop in pressure in the conduit (22) resulting from escape of compressed gas when the distal end (38) is melted by the rising molten metal is detected and signalled to a visible, audible indicator or directly to an electronic controller to discontinue pouring of metal (18) into the vessel (12).
