Coconut Creek (Florida), ISSN 0749-0208.Ultrasonic transducers are widely used in liquid sound velocity measurement. Acquisition of time-of-flight (TOF) is the key technology of high precision measurement of sound velocity.In this paper, to measure TOF with high precision, a Multi-strategy Measurement technique is proposed, which is able to locate the region of interest of the signals received echo waveform, and the wavelet denoising is carried out. To evaluate the proposed method, in an identified environment, the experiments were performed under defined the distance between transmitter and receiver in pure water at 30°C. The experiments were performed that, in the sound velocity measurement, the method has a high adaptability, which can achieve the goal of removing noise and improving detection accuracy. Although this paper focus on sound velocity in pure water, the method described may also find application in air.
