How to wire the electromagnetic flowmeter The wiring of the electromagnetic flowmeter is divided into two parts, internal wiring and external wiring. The internal wiring is generally 5 wires. The connection between the sensor and the conversion amplifier. XY, ACB, are the two wires of the magnetic field coil, XY, the electrode wireACB, two are electrode wiring AB, and one is grounding C. External wiring is generally the power input terminal. Second line, signal output line:Six, generally two 4-20MA output lines, two RS232 communication lines, and two RS485 communication lines. There is also a ground terminal wire on the cylinder.When buying the product and installing it, generally just open the meter cover and follow the instructions for external wiring, which is not complicated. But if the pipe is all plastic pipe and does not conduct electricity,It is necessary to properly ground to avoid flow inaccuracy or drift.
