As described above, according to the present invention, since the interface of the pulse column is detected by the settler provided outside the pulse column, stable interface detection can be performed without being affected by vibrations caused by pulses applied to the pulse column. Since there is no back pressure due to the height of the liquid level in the column, the measurement differential pressure ratio increases and detection accuracy can be improved.In addition, the interface detector can be inserted from the top. , the detection device can be easily maintained and replaced without affecting the interface. In addition, because the interface is controlled in a separate settler, there is little change in pressure on the interface due to changes in liquid density, and the interface is stable, making interface control easier. By attaching the column, interfacial products can be easily removed continuously without affecting the operation of the pulse column.
