摘要
本文介绍了一种动态跟踪反馈控制极化电压的实现方法,并分析推导了该方法的测量原理。设计出低功耗测量电路,编写基于Microchip单片机的软件程序。通过和已经标定好的电磁流量计进行比对测量,从理论和实验两方面都证实了电磁流量计采用恒磁励磁的方法的可行性。
A controlling method of polarization voltage using dynamic tracking feedback method is introduced in this paper. The measuring principle is analyzed A low power consumption measuring circuit and software program based on Micriochip single-chip microcomputer were designed. The feasibility of the method for electromagnetic flowmeter is proved with theory and experiment by being contrasted with the electromagnetic flowmeter calibrated
