摘要
本文根据节水科学管理的要求 ,介绍一种采用双喷嘴侧射流测量机构和磁电转换的流量测量原理 ,利用隔膜阀控制机构和防窃水结构 ,由 IC卡和单片机系统组成的一体化 IC卡水表。该一体化 IC卡水表体积小巧 ,功能完备 ,安全可靠 ,水电安全隔离 ,实现了用户凭卡购水、凭卡用水的科学管理 。
According to the requirement of scientific management in saving water, this paper introduces a kind of principle of flow measurement that adopts siding structure efflux with double. Spray nozzle and magneto electric transformation, which uses diaphragm valve and water steelingproof to compose integration of IC card water current meter by IC card and monolithic processor.It is characterized by small volume perfect function reliable safety and complete separation between water and electricity,and realizes scientific management through which the users purchase and consume water by IC card. It deserves vigorously popularizing and applying in the work of scientific management in saving water.
