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（0.6…800m3/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（2mm…300mm)。        

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
