Existing flow measurement methods calculate flow under the assumption that the movement of fluid is symmetrically distributed. However, the velocity distribution of the actual site displays turbulence, indicating that the velocity is irregular and asymmetrical. Accordingly, existing measurement methods pose accuracy problems, displaying a considerable difference with the actual flow value. Especially, they cannot be installed in partially filled pipes, or they display a rapid increase in errors. In order to resolve these problems, this thesis removed turbulence by installing a straightener and explained the results of developing the flow measurement device that displays excellent performance with no relation to the use of the fully filled pipe, through the ADCP(Acoustic Doppler Current Profiler) that uses the principle of the ultrasonic Doppler in the end part. The experiment was carried out a total of three times at a nationally recognized calibration agency, and the results confirmed a significant improvement in accuracy, compared to the flowmeter currently installed and operated on site, by displaying an error rate of 0.56%~2.68% on the rectangular open channel and 0.09%~1.49% on the partially filled circular pipe channel. Accordingly, the results are deemed useful in water measurement under the restricted conditions of partially filled pipes and the occurrence of turbulence.
