The Ultimate Guide To ultrasonic distance transducer

Soil erosion includes the three processes of soil separation, it is sediment transport and sediment deposition. The study of the hydrodynamic conditions of ultrasonic distance sensor

is the development of hydrodynamic mechanisms and the mutual influence of each process, which is the basis for establishing the soil erosion process model. Slope flow depth is a commonly used for hydrodynamic parameter, and it is also the basis for calculating slope flow velocity, it is flow shear force, and water flow power. 

Therefore, accurate determination is the key to discuss the hydrodynamic mechanism of mounted outside ultrasonic transducer, especially in the erosion. Slope surface water depth is usually no more than a few centimeters, which is a typical thin layer of water flow. It is difficult to measure it directly. At the same time, the evolution of underlying surface morphology in erosion process increases the difficulty of water depth measurement. The commonly is used depth measurement methods in the indoor erosion static bed experiments include direct and indirect measurements. Direct measurement mostly uses rulers, vernier calipers and digital display stylus, because the2Mhz ultrasonic transducer on the slope surface is very small, and the direct measurement method has significant errors when the sediment concentration is high and the flow color changes. At the same time, it is multi-sectional measurement, It takes a long time and affects the test progress.The indirect measurement method is to reverse the depth of the slope flow by measuring the flow velocity. 

Commonly used for flow rate measurement methods includes dyeing method, it is salt solution method, hot film flow meter, etc., while the dyeing method of ultrasonic oil level sensor requires a second modification of the measured surface flow rate, and the result of the salt solution method is affected by the length of the measured flow area and the salt concentration distribution function. The hot film flow meter cannot measure the velocity of the flow containing sand, thus affecting the accuracy of the water depth calculation. The ultrasonic wave has good directionality and strong penetrating ability, and it is easy to obtain concentrated sound energy. The speed of ultrasonic oil tank sensor does not change with the frequency of sound waves, and the speed is constant in a uniform medium, which is suitable for distance measurement technology. Ultrasonic ranging transducer has been applied to surface roughness,it is river water level, flow rate, and flow velocity, but there are few reports on the application of surface water depth measurement.the system parameters is debugging and testing measurement system .the ultrasonic depth sensor is used for measuring the depth of erosion on static bed. 500khz ultrasonic transducers are carried out which is aiming to measure the flow depth of the eroded static bed slope surface quickly ,and to calculate the relevant hydrodynamic characteristics of the slope surface.
