[0030] By setting the marking component 3, the driving motor 303 drives the lead screw 304 to rotate, thereby driving the slider 305 to move up and down, and then driving the marking arc piece 301 to move up and down. The height of the marking arc piece 301 is read in cooperation with the scale line 307. When the height rises to 0%, 25%, 50%, 75% and 100%, the electric push rod 309 drives the marking arc piece 301 to move to the right, so that the ink-absorbing strip 302 on the inner wall of the marking arc piece 301 fits against the outer wall of the float level gauge main body 201, and the five height points are marked with the ink on the ink-absorbing strip 302. There is no need for the operator to climb to a high place for five-point marking, which saves manpower and has higher operation safety. At other times, the electric push rod 309 drives the marking arc piece 301 to move to the left and does not fit against the outer wall of the float level gauge main body 201.
