涡轮式流量计(传感器)

FR70系列

原理,结构                                                                                     

涡轮流量传感器由主体、前支撑、涡轮、磁电接近式传感器、后支撑、导流器、轴承等组成。磁电接近式传感器内设置有永久磁铁,感应线圈和放大单元,当被测流体经过流量计时,推动涡轮旋转,涡轮周期性地改变磁路的磁阻值,使通过线圈的磁通量发生周期性变化,从而在线圈内感应出脉动电信号,经放大和处理后传送至二次仪表,或就地作现场显示,以实现流量积算。          

特点                                                                                          

不锈钢材质,*式安装,测量范围广(0.6800m3/h),*小的压力损失,良好的重复性及测量精度,机械部分与电子部分*隔离。适用于多种管径(2mm300mm)        

应用

液体配送系统,循环水测量,过滤系统,化工生产,泵保护, 适用于液体
