情２内の液面検出作用が行われるのである。Operation of the air valve 9 (by supplying air from the extrusion air supply path 8a to the rear part of the piston 1o, the Shirorad 6 is extruded and the outer peripheral surface of the IL1 electrode rod 6 slides along the lip 4. The brimmed air chamber 7 is led out, and the flanged tip 6
b is introduced into the liquid tank 2 at the same time. In this state, the liquid level detection function in Lust 2 is performed.

ーによる汚泥や汚物等の排除作用が有効に行われる。If a layer of sludge, filth, etc. forms on the outer circumferential surface of the electrode rod 6,
When the air valve 9 is operated, air is sent from the air intake path 8b to the front part of the piston 1o, and the rod 6 is moved back. By doing so, the outer circumferential surface of the electrode rod 3 will slide along the lip 4 and be introduced into the gas reservoir 7, so that the electrode rod 3
The sludge, filth, etc. that had adhered to the outer peripheral surface of the tube are scraped off by the lip 4 and collected on the back surface of the flanged tip 5b. Since the air is being supplied to the air retention chamber 7, the air in the air retention chamber 7 leaks from the sliding part 11, and the scraped sludge, filth, etc. are removed. If the tip portion 6b of the electrode rod 6 is formed into a brim shape, the action of removing sludge, filth, etc. by air can be effectively performed.

せ得るのである。Moreover, since the cleaning operation and the operation of restoring the electrode rod 3 to its original position after cleaning are performed at the same time by operating the air switching pulp 9, it is difficult to clean the electrode rod 6. If there is no need to stop the drive of the device and the liquid level does not reach the rising or falling limits,
The electrode rod 6 can be cleaned while the suction and discharge action continues.
