Microwave type hot metal level meter in a torpedo car was developed by Kawasaki Steel. One point of development is an improvement in gain and directivity of the antenna by the use of parabola type, and the other is an improvement in signal processing by microprocessor. It achieved the measuring accuracy ±50 mm.
This level meter was installed at Chiba No. 6 blast furnace for practical use and has been working satisfactorily. It has contributed to lightening the operators' load for watching and increase in efficiency of hot metal transportation.
