Abstract
The multi-hole probes are less expensive and accurate devices for measurement of velocity in three-dimensional flow field. In order to measure absolute velocity and its inclination with reference direction at the inlet and outlet of water turbine runner two five-hole angle tube probes were designed, fabricated and calibrated with low expenditure. The yaw-pitch calibration device was designed to set the probe tip at different angles in yaw and pitch planes. The calibration data was prepared and graphs plotted by using MATLAB R12014. The correction factor for each probe was found out to give real values of velocities measured by probes. The range of flow angularity in yaw and pitch planes is between −30 and +30°. During application flow angles, total and static pressure at probe tip, velocity and its components can be computed from measured values of pressures at five ports and calibration data.
