1. Wiring diagram of split type sewage electromagnetic flowmeter

The wiring of split type sewage electromagnetic flowmeter is divided into two parts: internal wiring and external wiring. The following is a detailed explanation: The internal wiring is the connection between the sensor and the conversion amplifier, with a total of 5 wires, as follows: Excitation coil wiring: 2 wires, marked as XY, used to provide current to the excitation coil and generate a stable magnetic field. Electrode wiring: 2 wires, labeled AB, used to collect induced electromotive force signals generated by fluid flow. Grounding wire: 1, marked as C, used to connect the sensor housing to the ground, ensuring equipment safety and reducing interference. External wiring is mainly used for power input and signal output, as follows: Power input terminal: 2 wires, used to connect external power sources (usually 24V DC) to provide working power for the flowmeter. Signal output line: 6 wires, divided into the following three categories: 4-20mA output line: 2 wires, used for transmitting differential current signals proportional to flow rate, suitable for long-distance transmission and connection with PLC, DCS and other systems. RS232 communication cable: 2 wires, used for short distance serial communication, can be connected to a computer or upper computer for data acquisition and parameter setting. RS485 communication cables: 2, used for long-distance serial communication, supporting multi-point communication, suitable for distributed control systems in industrial sites. Grounding terminal wire: located on the cylinder, used to ground the flowmeter as a whole, ensuring equipment safety and reducing electromagnetic interference. Grounding preca

utions for wiring: If the pipeline is made of non-conductive plastic material, it must be properly grounded, otherwise it may cause inaccurate flow measurement or signal drift. The grounding resistance should be less than 10 Ω to ensure reliable grounding. Anti interference measures: The signal output line should be kept away from strong electromagnetic field sources (such as high-power motors, frequency converters, etc.), and shielded cables should be used and grounded at one end if necessary. Power supply stability: A stable power supply should be used at the power input end to avoid voltage fluctuations affecting measurement accuracy. Wiring sequence: First complete the internal wiring, then connect the external power and signal lines, and finally ground the potato skin. Installation steps: Open the flowmeter cover and connect the internal wiring (XY, AB, C) according to the instructions. Connect the external power line (24V DC) and signal output line (4-20mA, RS232

2, RS485). Ensure the grounding terminal wire on the cylinder is reliably grounded. Check if all wiring is securely damaged by hand and if there are no short circuits or open circuits. Power on test to confirm that the flowmeter is working properly. By following the above steps, the wiring and installation of the split type sewage electromagnetic flowmeter can be completed, ensuring its stable and accurate measurement of sewage flow rate.
