摘  要:电磁水表的励磁频率是影响计量性能的重要因素。因其采用电池供电的模式,厂家为延长水表使用寿命,通常选择降低励磁频率以降低功耗。探讨了一种基于霍尔效应原理设计的检测装置,能有效检测电磁水表励磁频率,从而评价电磁水表计量性能的可靠性。The excitation frequency of the electromagnetic water meter is an important factor affecting the measurement performance. Because of the battery-powered mode,manufacturers often choose to reduce the excitation frequency to reduce power consumption in order to prolong the service life of the water meter. This paper discusses a detection device based on the principle of Hall effect,which can effectively detect the excitation frequency of electromagnetic water meters,so as to evaluate the reliability of the measurement performance of electromagnetic water meters.
