ことを目的とする。In the above-mentioned conventional ultrasonic type detecting device and magnet-level switch type detecting device, the boundary surface level can be measured only at the fixed position as described above, and the boundary surface level in real time can be measured. Is impossible to measure. In addition, since the ultrasonic detection device has different characteristics for the ultrasonic wave of the substance, it requires a dedicated level meter for liquid and solid, and the detector itself is expensive, so high-cost measurement is possible. There is a problem that it becomes a device. In addition, the magnet-level switch type detection device has a problem in that the probability of failure is high because the mechanical part is housed in a container. It is an object of the present invention to provide an optical boundary surface measuring device that solves such problems.
