영문 초록

The flow meter detects the vortex made by the bluff body which is inside of the pipe that has flowing fluids and calculate the velocity of the fluid. The sensor was manufactured using sensor body and piezo ceramics as the result of the creative design in engineering. The preexistence was analyzed and considered manufacture process and experiment. The sensor body was made after modifying sensor housing and transmitter. Using an elastic tape, copper foil and electric wire, first experiment was conducted. After holding with a vise, impulse was given to the transmitter and signal was captured. Scale is the 100㎳/dev for horizontal direction, 100㎷/dev for vertical direction. And the signal of the preexistence and proto-type was similar with its amplitude and period. Also, through frequency analysis, piezo ceramics’ thickness was selected and it can reduce the cost and error from development step. The experiments include impulse and periodic impulse test.
