本发明解决技术问题采取的技术方案是，对照附图，进行说明，图1、图2中本发明是由铜轴电缆1、铜管2、不锈钢外壳3、极性检测体4、永磁体5、磁场检测线圈6、正负电极7、导线板8、屏蔽板9、线圈支架10、塑料件11、智能部分12组成，其中正负电极7固定在导线板8上，套在铜管2里的铜轴电缆1也固定在导线板8上，屏蔽板9在导线板8的上侧，支架10在永磁体5和磁场检测线圈6间，塑料件11紧靠永磁体5，极性检测体4在所述一种插入式永磁流量变送器的上端一侧，不锈钢外壳3在外侧，所述的一种插入式永磁流量变送器，其特征在于，永磁体5是“E”形状(见附图2)，其外侧两极的形状均与水平成45度角。
本发明与现有技术相比，本发明的有益效果是：采用永磁体，可使功耗小，可电池供电，水质要求较低，可以长期使用，永磁体的“E”形，使磁体的磁泄露大大减少，精度高，磨损小，结构简单，成本低，从多方面起到积极的效果。
附图说明
下面结合附图对本发明的具体实施方式作进一步详细的说明。
图1是本发明产品安装示意图。
图2是本发明产品A-A剖面示意图。
图中1.铜轴电缆，2.铜管，3.不锈钢外壳，4.极性检测体，5.永磁体，6.磁场检测线圈，7.正负电极，8.导线板，9.屏蔽板，10.支架，11.塑料件。
具体实施方式
正负电极7固定在导线板8上，套在铜管2里的铜轴电缆1也固定在导线板8上，屏蔽板9在导线板8的上侧，支架10在永磁体5和磁场检测线圈6间，塑料件11紧靠永磁体5，检测极性体4在所述一种插入式永磁流量变送器的上端一侧，不锈钢外壳3在外侧，所述一种插入式永磁流量变送器，其特征在于，永磁体5是“E”形状，其外侧两极的形状均与水平成45度角。
当永磁体5产生磁场，正负电极7检测到水中极性时，产生电动势，通过固定在导线板8上的铜轴电缆1将相应信号传到智能部分12，磁场检测线圈6检测永磁体5磁性情况，通过导线接到智能部分12，从而根据永磁体5的磁性变化情况更改智能部分12的计算参数，起到准确测量的目的，极性检测体4检测正负电极7极性情况，通过导线接到智能部分12，从而根据正负电极7极性变化更改智能部分参数的设置，起到准确测量的目的。
