electromagnetic flow meter application

The connection method between the electromagnetic flowmeter and RS485: Connect the TXD and RXD of the flowmeter to the RX+ and RX- of the RS485. If the connected wire is relatively long, a matching resistor of 100-200 ohms can be added at the remote end, and then plug the RS485 into the serial port of the microcomputer. After the connection is completed, how do we know that the connection is correct and no errors have occurred? Test method for 485 communication of electromagnetic flowmeter

The structure of an electromagnetic flowmeter mainly consists of multiple key components, which work together to measure the flow of conductive liquids. The following are the main structural components and functions of the electromagnetic flowmeter:

Electromagnetic flowmeters are used to measure the volume flow of industrial liquids and there are many media in industrial liquids, electromagnetic flowmeters are often used to measure the flow of conductive media.
