Abstract

The invention discloses a liquid level measuring method of a pressure vessel for the aluminum oxide industry, a medium in the aluminum oxide pressure vessel can generate sound waves in the flowing process, the frequency of the sound waves is related to the liquid level of the medium in the vessel, and a sound sensing element is arranged at the bottom of the pressure vessel to receive the sound waves; conversion is carried out according to a formulated sound wave frequency-liquid level height characteristic relation formula, and non-intrusive liquid level real-time monitoring of media in the container is achieved during production and operation. Non-intrusive liquid level measurement is achieved according to the characteristic relation between sound waves generated in the flowing process of a medium in the pressure container and the liquid level of the medium in the container, and the problem that the liquid level of the pressure container is difficult to measure under the severe working conditions of high temperature, high pressure, strong acid, strong alkali and the like in the aluminum oxide production process is solved; the influence of the working environment on liquid level measurement is greatly reduced, the liquid level measurement cost can be remarkably reduced, operation is easy, use is convenient, no additional energy consumption exists in the operation process, and liquid level measurement is more efficient, reliable, energy-saving and safe.
