測定装置。In a molten steel level measuring device that measures the level of molten steel in a mold by magnetic interaction between the mold wall or the molten steel itself and a coil, the amplifier for amplifying the signal obtained from the coil is a variable gain amplifier, and A means for giving a gain change command to the amplifier at an arbitrary molten steel surface level, and a comparator operated by the gain change command signal to compare a fixed reference value with the measured value are provided, and the output of this comparator is used to change the above mentioned variable. A molten steel level measuring device that adjusts the gain of a gain amplifier and is equipped with a zero suppression circuit to remove unnecessary signals.
