ABSTRACT:
This invention relates to an apparatus and method for directly measuring the bottom pour flow rate from heated ceramic crucible, hearth/tundish combinations used in metals refining/processing industry, plasma arc melting process (PAM), a cold hearth process or other similar processes such as for pouring ingots. Such structures of this type generally allow the bottom pour flow rate to be accurately measured in relative real time without adversely affecting the flow while withstanding the hostile surroundings typically associate with a heated crucible, tundishes, PAM, cold hearth process or other similar processes.
