Research on the Measurement Techniques of Terrain and Velocity in the Model Experiment with Hyper-concentrated Flow
This paper focuses on the measurement techniques of terrain and velocity in the model experiment with hyper-concentrated flow.During the measurement of the terrain,it can adjust the transmission frequency of the ultrasound terrain equipment to adapt to the variation of the sediment concentration.To reducing the interference from the electromagnetic,an electromagnetic damper has been used to measure the speed of the flow through the high-frequency sampling techniques.Meanwhile,the measurement and control system has been developed,including hardware such as the measuring bridge,surveying vehicles and other equipment equipped with the terrain meter and flow meter,and software which can achieve the terrain model experiment and automatic measurement of the flow speed through setting the parameters of the measuring section and the measurement model.
