摘要
传统电磁流量计在消除微分干扰时大多数采用在硬件电路上消除或者避开微分干扰时段进行采样,很少研究影响干扰的原因。基于真实电极情况,建立电极回路测量模型并基于模型进行电极信号仿真,研究了传感器参数和电极参数变化对微分干扰的影响。结果表明,当参数取值不同时尖峰干扰也不相同,从而为研究和消除干扰减小测量误差提供理论依据。
Based on the real electrode condition,the electrode loop measurement model is established and the electrode signal simulation is carried out based on the model.The effects of different sensor parameters and electrode parameters on differential interference are studied in this paper.The simulation results show that the peak interference is different when the values of the parameters are different,which provides a theoretical basis for studying the differential interference and eliminating the interference to reduce the measurement error.
