[0021] A fixing mechanism for fixing the liquid level meter is provided in the placement frame 11 . The fixing mechanism includes a plurality of bolts 18 arranged on a plurality of side walls of the placement frame 11 . A knob is provided on the bolts 18 .

[0022] In the utility model, a protective cover 12 is fixedly connected to the lower end of the top plate 1, and a mounting plate 6 is fixedly connected to the lower end of the protective cover 12. The mounting plate 6 can be installed on the top of the deoxidation tower, and the mounting plate 6 can be installed on the top of the deoxidation tower without the need for the mounting plate 6, so that the distance between the lifting plate 9 and the deoxidation tower can be smaller, so that the liquid level meter can detect higher noble liquids.

[0023] In the utility model, a mounting ring 7 is fixedly connected to the lower end of the mounting plate 6, a laser rangefinder 15 and a wireless module 14 are installed on the side wall of the mounting ring 7 through a mounting rod, a receiver 10 is provided at the upper end of the lifting plate 9, and a controller 13 is provided on the top plate 1. The position of the lifting plate 9 can be detected by the laser rangefinder 15, so that the descending position of the lifting plate 9 is more accurate.

[0024] In the utility model, the upper end of the lifting plate 9 is fixedly connected with a mounting frame 16, and a camera 17 (with its own light source) is installed at the bottom of the mounting frame 16. The corrosion condition of the interception block can be observed through the camera 17, which is convenient for timely replacement.

[0025] In the utility model, a protective pad 19 is provided at the other end of the bolt 18 to avoid pinching the intercepting block of the displacement meter.
