Abstract

The halon is usually stored in the sealed highpressure steel containers at liquid state, which can not be detected the liquid level by using the traditional contact-type method. In this paper ultrasonic is used to measure the liquid level which achieved the purpose of nondestructive testing, the model of residual ultrasonic waves in the container's wall was used to determine the liquid level. We choose the wavelet threshold denoising in the wavelet transform to remove the noise in the sampling signals, by comparing the envelope area in two different states that the transducer below or on the actual liquid level to judge the results. It has been proved after repeated tests that this method operates simply, and has a more accurate conclusion.
