The outer wall 34 and the inner wall 35 are integrally formed, and a chamber 37 created by them is filled with a piece of iron 39 as a weight and a burst of polystyrene foam 40 below. Thereby, the float part 33 can be slightly submerged in the liquid surface 41 and float. A screw 42 is cut from the upper entrance of the inner wall 35, and the sensor section 1 is accommodated by the screw 43 of the mounting section 36. The mounting part 36 is also cylindrical, and a screw 44 is cut in the lower part of the inner wall of the mounting part 36, and is engaged with the peripheral edge 12 of the upper part 9 of the lead-out part 3 of the sensor part 1 with the screw. In this way, the sensor part 1 is attached, but the lower part of the inner wall 35 protrudes inward,
The protruding portion 45 supports the protective portion 5 of the sensor portion 1. Therefore, the protective portion 4 is arranged such that the lower surface 25 of the sensor 4 forms a spherical surface together with the outer wall 34.
The protruding portion 45 engages with the protruding portion 45 .

Reference numeral 55 is a stand, which is erected on the liquid level.
Two support rods 56A and 56B are erected from 5. This support rod 56 includes a rod 5 that protrudes toward the front in the figure.
There are six 7's. The range of movement of the arm 50 is also determined by the height of the rod 57. Furthermore, as shown by the broken line, it absorbs fluctuations in the liquid level 41 and assists in maintenance and inspection.

With the above configuration, for example, on the water surface, the fixture 51 is attached to the top bar 57 of the support bar 56A as shown in FIG. tighten. Then, the float portion 33 floats due to fluctuations in the liquid level 41 or due to bubbles sent into the water to increase the oxygen concentration. At this time, the float part 33
The bottom surface of the sensor 4 is the lower surface 25 of the sensor 4, and forms part of a spherical surface, as shown in FIGS. 1 and 2. Therefore, the lower surface 25 of the sensor 4 is constantly being washed with water flow. Furthermore, since it is not flat and floats due to the action of the fixture 51, it is easy to clean.

As described above, according to the present invention, since the sensor section is embedded in the float section and the sensor is easily cleaned with a stream of water or bubbles, it is possible to provide a self-cleaning function very easily. Therefore, it is possible to prevent the device from becoming more complicated, larger, and more costly, and is extremely convenient.

In addition, the measurement of dissolved oxygen concentration in the present invention is as follows:
The current obtained from the sensor 4 is guided by a cable 6 through the sensor section 1 and the arm 50 to an amplifier (not shown). Thereafter, the current is amplified, and the concentration is output as a voltage, for example, from a comparison with the saturation concentration, which is normally performed, and a meter is oscillated by this.
