TECHNICAL FIELD

[0002] As an important flow measurement tool, electromagnetic water meters are widely used in industrial, agricultural and urban water supply systems. Traditional electromagnetic water meters usually use wire harness connection to realize electrical connection between various components. Although this connection method can meet the basic use requirements, it has some shortcomings in actual application.

[0003] Common wire harness connection methods mainly include hard wire harness connection and plug-in connection. Hard wire harness connection fixes the lead-out wires of various components together by welding or crimping. This method has the advantage of firm connection, but has the disadvantages of complex assembly, easy error and difficult maintenance. Plug-in connection realizes quick connection through special plugs and sockets. Although this method is simple to operate, the contact between the plug and the socket may be poor, resulting in unstable signal transmission. In addition, there are some simple binding connection methods, such as using insulating tape or buckles to fix the wire harness. This method is suitable for small devices, but for large electromagnetic water meters, the reliability is low and it is difficult to ensure long-term stable operation.

[0004] However, the above various wire harness connection methods generally have problems such as complex assembly, easy error, difficult maintenance and easy shaking, especially in situations requiring high precision and high consistency. CONTENT OF THE INVENTION

[0009] Optionally, the flexible flat cable structure and the flow guide pipe are connected through the signal electrode and the grounding electrode, and are locked and conducted through the nut.

[0010] By adopting the technical scheme, the grounding electrode effectively improves the signal stability, reduces external interference, the signal electrode accurately measures the induced electromotive force, and further improves the measurement performance of the water meter.
