| 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。本流量计采用西6mm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0．8776mL，其有效测量量程为0．05—0．5m^3／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. |
