| Abstract: | This paper designed the part of hardware circuit of secondary instrument of capacitive vortex flow meter. Signal conditioning circuit was designed including a preamplifier circuit, filter circuit, and smith shaping circuit. The button interface circuit and LCD display interface circuit were designed by MSP430F149 as the core and the power circuit of secondary instrument was designed. Practice proves that the circuit can realize the signal control and processing of capacitive vortex flow. |
