abstract

Measurement accuracy of flow velocity by phased array UVP method was confirmed in order to develop a basic telemetry system for detections of leakage points. The basic telemetry system which consists of a robot arm for moving ultrasonic sensor and a phased array sensor for wide range area measurement of flow velocity was developed. Additionally, flow mapping of water flow around imitated leakage was conducted by the developed system and PIV method. As a result, the velocities by both methods were in agreement with 20 %. The possibility of measuring two-dimensional velocity of flow near the leakage point by the developed telemetry system was verified. Consequently, the basic telemetry system for the detection of the leakage was established.
