RIVER FLOW MEASUREMENT USING ULTRASONIC DOPPLER METHOD

Abstract

In this paper the study on the application of ultrasonic Doppler method to a river flow is reported. This method uses a pulsed ultrasonic echography together with detected instantaneous Doppler shift frequency to form a velocity profile. Velocity profiles measured by this method and the Electromagnetic Current Meter were compared, and similar profiles were obtained. And a software which can calculate a river flow rate by using velocity profiles from some ultrasonic transducers has been made, then a real river flow rate were obtained from this software.
