Measuring the bedload transport rate is utmost interest to understand and quantify all sediment transport related phenomena. Three existing bedload measuring systems are 1) the hydrophone, 2) the geophone, and 3) the plate microphone as their modified system. All systems estimate transport rate based on sediment impact, whereas each has respective disadvantages. In this paper, as the other improved system, plate-type vibration sensor is discussed. Calibration experiment is conducted and the system is compared with the other plate hydrophone. In the experiments, impact data is perceived as both vibration pressure and vibration pulse, and analyzed the same as plate microphone. Although it has been clarified that fine sediments lower than 10 mm are not detectable with plate hydrophone, plate-type vibration sensor detected vibration pulses of them clearly. Moreover, detection rate can be linked to the sediment bulk density and the gravel jump length.
