Ultrasonic Measurement System About Vertical Distribution of Sediment Concentration

摘要

According to the theory of ultrasonic reflection measuring sediment concentration, the paper puts forward a method of ultrasonic reflection to measure vertical distribution of sediment concentration simultaneously, and introduces the measurement system about vertical distribution of sediment concentration. Practice has affirmed that the system can automatically measure the vertical distribution of sediment concentration in the low sediment concentration, and its precision has filled the requirement in fact.
