Abstract
In order to improve the measurement lower limit and anti-interference ability of the swirlmeter, the internal voltage-variable crystal acquisition circuit of the swirlmeter is given. A detection circuit composed of three Instrumentation amplifier and a voltage-parallel negative feedback circuit is adopted here to eliminate the effect of power-frequency noise interference, the input impedance is increased and the lower limit of the range is expanded, The experimental results show that the swirlmeter designed by the improved circuit has a wide range and anti-jamming performance, the accuracy can reach 1% in the measurement range.
