  • Apparatus for measuring distribution of flow rates of flowable medium
    Patent number: 6687626
    Abstract: A flux distribution measuring apparatus measures distribution of flow rates of a flowable medium. The measuring apparatus includes thin metal wire(s) for scanning a flowable medium and lead wires connected to the thin metal wire(s), wherein a voltage difference is detected between adjacent lead wires while the measuring apparatus scans the flowable medium in the direction perpendicular to a flow path of the flowable medium. The voltage differences are generated due to temperature changes in the thin metal wire(s) while scanning the flowable medium having different flow rates. The measuring apparatus visualizes the distribution of flow rates of a flowable medium using a computer which receives and processes the voltage differences detected.
