Abstract(in English) | The goal of this study is to measure the residual volume of liquefied gas in a gas cylinder accurately by measuring the acoustic responses to a mechanical excitation applied on the outside of the gas cylinder. First, we investigated the vibration mode of cylinder through both measurements and finite element method. We analyzed the change in the resonance frequencies theoretically by assuming that liquid worked as loaded mass to the gas cylinder wall. The mass-loading effect is expressed by an analytical form and the water level can be calculated by the equation from the peak frequency. Then, it was shown experimentally that our method for residual volume estimation was valid for a 10.3ι gas cylinder with the error of less than 5.2%. It was also demonstrated that that the error was reduced by using the corrected vibration distributions. We confirmed that the method was valid also for glass bottle. |
