A study on a Characteristics of Eddy current Flow meter

In this paper, the eddy current flowmeter with 4-coil is designed and made on the basis of theory, and its characteristics is considered through dry test and flow experiments. The biggest output signal varied with wave wave form frequency, and 900Hz in rectangular wave, 27.12kHz in sine wave. The conductivity is bigger, the output signal is bigger and has a linearity between both relation, and also The Magnetic Reynolds Number and output characteristics The flow faster and the output signal is bigger.
