The main guide rod 7 arranged between the lower guide rod fixing block 5 and the upper guide rod fixing block 6 is used for the floating of the gear-shaped floating buoy 8. Utilizing the buoyancy of the liquid, the upper surface of the floating buoy 8 is always flush with the liquid surface. On the one hand, the actual liquid level can be observed from the outside. At the same time, an auxiliary guiding and sliding assembly 9 and a floating calibration and observation assembly 10 are also provided. Through the secondary calibration method, the reading of the liquid surface is achieved.
[0021] In one embodiment, please refer to the attached drawings of the specification Figure 2 As shown, an auxiliary guiding and sliding assembly 9 is embedded in the upper guide rod fixing block 6.
