The authors attempt to understand the complicated flow inside a suction sump in the vertical-wet-pit-pump configuration. A three-dimensional particle tracking velocimetry (3D-PTV) technique is appropriate for this kind of flow. However, this technique includes more unknown factors in reliability and accuracy than other well-established measuring techniques. So, the authors examine the simultaneous measurement using both of the 3D-PTV and an ultrasonic velocity profiler with common tracer particles. As a result, the authors have successfully found out the suitable condition for the simultaneous measurement with high accuracy. Then, under this condition, the authors have revealed the time-mean and instantaneous velocity vectors of the flow inside the suction sump.
