摘要：
Most commercial slurries in hydrotransport pipelines usually contain some gas which can considerably degrade the pump performance, but this small amount of gas content can not be measured accurately online or continually using conventional methods. Based on analysis of effects of gas on pressure wave speed in slurries, an investigation was carried out to validate the feasibility of the method to determine gas content in slurries using sound speed. Moreover, its practical measuring methods were also discussed. It was found that the non-invasive measurement of the sound level noise spectrum across the pipeline should be a promising online measuring method of the slurry gas content.
