| Abstract: | Based on the behavior of ultrasonic propagation in water flow containing air bubbles, a new equipment for the measurement of concentration of entrained air in water flow is development. It has advantages in operation, installation, real time measurement and Dn line read out of concentration of entrained air, and thus can be an effcient equipment for field measurement and indoor model research in hydraulic engineering. |
