[0021] Such as figure 1 and Figure 4 As shown, the magnetic-inductive liquid level measuring device includes a buoyancy mechanism 10 , an induction mechanism 20 and a display mechanism 30 .
[0022] The buoyancy mechanism 10 comprises a track 11 and a buoyant member 12, the track 11 is fixed inside the container 100, and the lower end of the track 11 is connected with the bottom of the container 100, and the upper end of the track 11 is connected with the top of the container 100; the buoyant member 12 is connected with the track 11, and It can float along the longitudinal direction of the track 11 under the action of buoyancy. The buoyancy member 12 is magnetic, and its outer surface is made of non-metallic material.
[0023] The sensing mechanism 20 is not in contact with the liquid in the container. The sensing mechanism 20 includes a body 21 and a plurality of circuits 22. The body 21 is connected to the container 100 and is close to the track 11. The two ends of the bod...

[0035] Such as figure 2As shown, in this embodiment, the container 100 is a double-layer container, and the wall of the container 100 includes a sleeved inner wall 110 and an outer wall 120 , and the sensing mechanism 20 and the display mechanism 30 are located outside the container. The track 11 is disposed on the inner wall 110 , and the body 21 of the sensing mechanism 20 is disposed on the outer wall 120 . The body 21 covers part of the outer wall 120 and has the same shape as the covered part of the outer wall. Two ends of the track 11 are connected to the inner wall 110 and cover part of the inner wall 110 , and have the same shape as the covered part of the inner wall 110 . The buoyant member 12 can float between the track 11 and the inner wall 110 . In this embodiment, the cross sections of the inner wall and the outer wall are both circular, and the cross sections of the body 21 and the track 11 are both semicircular. However, the shape of the above structure is no...

[0038] image 3 is a schematic diagram of the third embodiment of the magnetic-inductive liquid level measuring device according to the present invention. The difference between this embodiment and the second embodiment is that the track 11 is perpendicular to the container 100 , and the buoyant element 12 is sheathed on the outer periphery of the track 12 . The buoyant element 12 can be an annular cylindrical foam with built-in natural magnet.
