摘　　要：基于近年来磁阻传感器的技术发展,提出了一种利用磁阻传感器在电子式水表、气表中应用的设计思路,克服了水表、气表中干簧管作为脉冲发讯装置在计量过程中可靠性低、响应速度慢、功耗大等缺点,最终实现了水表、气表计量输出精确,整机降低功耗低的目的。The reed switch is adopted as pulse output device for metering in water meter and gas meter. To overcome the disadvantages of low reliability, slow response speed, and high power dissipation, we present a design of magneto-resistive sensor application based on the technique development of magneto-resistive sensor, which realizes the accurate metering and low power dissipation in water meter and gas meter.
