WANG Shou-zhi. Design of electromagnetic flowmeter based on low-frequency sine waveform exciting mode[J]. 2011, 30(2): 119-121. DOI: 10.13873/j.1000-97872011.02.006.
A design method for electromagnetic flowmeter adopting low-frequency sine waveform exciting mode is proposed.A new method for signal processing which is more convenient and reliable than the traditional ones is adopted.The results show that low-frequency sine waveform exciting mode could reduce the influence of differential interference at the stage of low flow velocity
enhance stability of zero point and accuracy of the flowmeter.
