Research and Test of Liquid Level Detection Based on LNG Natural Vibration Frequency

With the shortage of fossil energy and the popularization and application of new energy sources, more and more LNG vehicles appear in people's lives, however, the dynamic liquid level monitoring of LNG tank with energy storage has become a difficult problem. In this study, a new method of monitoring the height of liquid surface by LNG natural frequency is proposed, and the algorithm of natural frequency based on elastic foundation is compiled, and compared with the test results, and verify the correctness of the method, and provides a new method for liquid level monitoring, it will have very important significance for popularization.
