A sealing device of a level meter is acid-and-alkali-resistant and pressure-resistant, and has a flexible outer tube, a plug, a female union connector and a male union connector. The flexible outer tube has an expansion neck formed on a bottom end thereof. The plug is mounted in the expansion neck. The female union connector is mounted around the expansion neck. The male union connector engages the female union connector by means of threaded engagement. The male union connector has a through hole for tying a weight such that the flexible outer tube is stretched along a force of a gravitational force of the weight. As being wholly and uniformly subjected to the gravitational force of the weight, the male union connector is less damage-prone. Accordingly, the tensile strength of the level meter is effectively increased, and a life duration of the level meter therefore prolongs.
