摘要
本论文介绍了一种应用在热量表中的流量测量系统,该系统使用TI最新推出的MSP430FW42系列单片机内部集成的Scan IF模块和一种无磁非接触式传感器来实现热水流量的无磁测量。详细地说明流量测量原理和数据的处理,在此分析的基础上给出系统电路原理图。根据测得的数据分析验证该测量系统的可行性。
This paper introduces a system of measuring flux in heat meter.This system applies two important parts to realize measurement that without magnetism,One is integrated block of Scan IF within a series of MSP430FW42x singlechips,the other is a sensor that is without magnetism and touch.The theory of flux measurement and data process are expounded.Circuit diagram of the system is provided based on the unalysis.The feasibility of this system is proved by expounded gained data.
