电磁水表是近些年新兴的智能水表2.0的全电子水表产品,是从电磁流量计技术发展而来,但电磁水表功耗要求更低、测量范围更宽,因而磁场发生方法和磁场分布至关重要。采用霍尔元件阵列对电磁水表内部的磁场分布进行检测,设计了相应的软硬件方案,实现了磁场分布的检测。
Electromagnetic water meter in recent years, the new smart meter 2.0 full electronic meter products, is derived from the electromagnetic flowmeter technology, but the electromagnetic meter power requirements lower, wider measurement range, and thus the magnetic field generated magnetic field distribution and distribution important. The Hall element array is used to detect the magnetic field distribution in the electromagnetic water meter. Corresponding hardware and software solutions are designed to realize the detection of the magnetic field distribution.
