Application Number: JP,2022-016348
Category (FI): G01F23/284
Stage: PROBLEM TO BE SOLVED: To accurately measure a liquid surface over 400 mm from the bottom of a casting mold to the liquid surface when measuring the liquid surface level of high-temperature liquid such as molten steel.SOLUTION: A level meter 1 comprises: a cylindrical guide pipe 10 that is disposed in parallel to a liquid surface 101 of high-temperature liquid 100 and propagates microwaves or millimeter waves in its internal space; an antenna 20 that is disposed opposite to one opening 10a of the guide pipe 10; transmission and reception means 30 for microwaves or millimeter waves that is connected with the antenna 20; and a reflecting plate 40 that is disposed opposite to the other opening 10b of the guide pipe 10, reflects the microwaves or millimeter waves transmitted from the antenna 20 toward the high-temperature liquid 100, and guides the reflected microwaves or reflected millimeter waves to the guide pipe 10. The pipe length L of the guide pipe 10 is adjusted to a length at which phase constants in a TE mode and a TM mode of the microwaves or millimeter waves match each other.SELECTED DRAWING: Figure 1 (Grant)
