 note = {application/pdf, In order to measure the flow in a centrifugal pump for low specific speed, a new system of PTV method is developed. This system uses the massproduced and cheap digital camera and LED(Light Emitting Diode) lamps. The tracer particles, which are lighted by red and green LED flash, are exposed into one picture image, and divided in the post process. There is no inner-clock, so this system can synchronize the rotation of impeller with good accuracy. Also the interval time between red and green flash can be changed freely. Using the blue markings for calibration in the flow area, we can distinguish these markings from particles during the measurement. Though the intensity of light must be improved a little more, the array of highbrighted LED can generate enough light to trace the moving particle.},
