Disc-shaped perforated plates 051 to 05n each having a large number of micropores formed in the column bodies of the upper B chamber 02 and the lower chamber 06 of the extraction column 01 are arranged in parallel to each other at predetermined intervals, for example, in 10 to 50 stages. ing. In the extraction tower 01, the heavy liquid phase and the light liquid phase pass through the perforated plates 051 to 05n, so that the heavy liquid phase and the light liquid phase come into contact with each other and the extraction action is promoted. In order to further promote the extraction action, a pulsed pressure wave is applied to the lower chamber 06 by a pulsating wave generator 08 to bring the N liquid phase and the light liquid into dynamic contact. The mixed two phases are dispersed in the upper chamber and the lower chamber, and the light liquid phase is transferred from the light liquid pipe outlet 04, and the light liquid phase is transferred from the light liquid pipe outlet 04 to the heavy liquid pipe outlet 0.
The heavy liquid phase is taken off from 10 in each case. For example, uranium and plutonium are extracted into the light liquid phase, and fission products remain in the heavy liquid phase.

Now, it is necessary to take out only the heavy liquid phase from the heavy liquid outlet pipe 010, but this requires constant monitoring of the interface 017.

Measurement chamber 12 is placed across the target interface position in advance.
The ultrasonic waves emitted from the array-type transducer 14 installed inside the coupling liquid 13 pass through the wall of the lower chamber 6, enter the light liquid phase and the heavy liquid phase, and hit the opposite wall. It is reflected and comes back in the original direction. This situation is illustrated in Figure 2 (a).
, K as shown in (b). Further, the signals obtained from the array type transducer 14 in the vertical direction of the interface are as shown in FIG. In FIG. 3, the sound velocity in the heavy liquid phase below the interface is faster than in the light liquid phase, so the propagation time of the ultrasonic wave is [light liquid phase propagation time>heavy liquid phase propagation time]. Therefore, for example, the interface position can be determined by counting the number of arrays in the portion where the propagation time is short, using the point of the array type transducer 14 as a reference, and multiplying the number by the array pitch.
