Abstract:
    A pipeline sound wave velocity detecting device consists of a transmitter, a receiver 1 and a receiver 2. The sound transmitter transmits sound wave pulses; the sound receiver 1 receives sound wave pulses transmitted by the sound transmitter through the pipeline; a wireless transmitter transmits the initial arriving time of the sound wave pulses to the receiver 1 transmitted by the sound transmitter through the pipeline to a receiver 2 after the interference being eliminated by the delay circuit; at the same time, the receiver 2 receives sound pulses transmitted by the sound transmitter through the pipeline and records the initial arriving time of the sound pulses to the receiver 2 transmitted by the sound transmitter after the interference being eliminated by the delay circuit. Thus, the sound wave velocity detecting is realized and is displayed on the liquid crystal of the receiver 2. The pipeline sound wave velocity detecting device has a high speed detecting precision and can be used for detecting the pipeline sound wave detecting, pipeline length detecting and pipeline leakage detecting etc.
