The presence of a vortex in stream allows a changes in flow velocity and direction, such as occured in the pump suction where the influence of pump impeller rotation has a significant impact to influence the direction of fluid flow inside. Changes of flow direction in turbomachinery is directly related to the work exchange. To understand about two dimensional flow velocity and direction, it’s then will be investigated in testing process by using direction-sensing probes method’s. A measuring devices, flow angle tubes, which consist of two impact tubes are fed by an incompressible fluid that in this case is water. The testing process is conducted at several flow velocity and angle of attack variation on the flow angle tube. All the test result then compared to theoritical calculation on the same condition. The data that we can be obtained is pressure difference between two tubes. This pressure difference enable us to know flow velocity and it’s direction. From this experiment result, we can obtain flow velocity and direction from flow angle tube and then the influence of angle of attack and tube’s diameter on the measurement accuracy. This result will be the subject for futher consideration about flow velocity and it’s direction phenomenon, their application and a better flow measurement device selection to perform this testing. Data from this testing process still has many weakness too, so that expected development and improvement are still needed for the next experiment.
