摘要

设计了一种用InSb-In共晶体薄膜磁阻元件制作而成的液体流量计

该流量计中的转动涡轮由磁钢材料制作

当转动的涡轮叶片靠近InSb-In共晶体薄膜磁阻元件时引起其阻值的变化

进而产生交变信号。经过对信号的处理

单片机进行计数

可以得到瞬时流量和累积流量。本流量计采用6 mm管径设计

实验中采用自来水作为被测液体

每脉冲代表液体流量为0.877 6 mL

其有效测量量程为0.05

.5m3/h

测量误差在±0.4%左右

能满足低流速测量工业现场的使用要求

并能降低制造成本。

Abstract

A flowmeter made from InSb-In eutectic film magneto resistor is designed.InSb-In eutectic film magneto resistor will change correspondently.At the same time

the AC signals can be achieved.Then them are sent to a microprocessor.the instantaneous delivery and integrated flux can be achieved.The diameter of this flowmeter is 6mm and its flux for per pulse is about 0.8776mL.In addition

the range of its effective quantifier is 0.05～0.5m3/h and its measurement error is about ±0.4%.The design requtiement can be fully met

and cost of the factry is reduced.
