Device for hanging waterproof bead on wall of liquid level meter

The utility model discloses a water-proof bead wall-hanging device for a liquid level meter. The water-proof bead wall-hanging device comprises the liquid level meter, a wedge-shaped assembly, a supporting plate and a purging pipe, the supporting plate is fixedly connected with the inner wall of the container, a mounting hole is formed in the supporting plate, a liquid level meter is arranged in the mounting hole in a penetrating mode, and the liquid level meter is fixedly connected with the supporting plate through a wedge-shaped assembly; the liquid level meter has the advantages that the installation angle of the liquid level meter can be adjusted through the wedge-shaped assembly, so that the end face of the probe of the liquid level meter is obliquely arranged, large-particle condensed water drops attached to the probe can flow into a container along the inclination angle of the end face of the probe under the action of the gravity of the condensed water drops, and the problem that the water drops are at
