Electromagnetic flowmeters are based on Faraday's law of electromagnetic induction, calculating flow by measuring the induced electromotive force generated by conductive liquids in a magnetic field. Its core components include a sensor and a converter; the sensor is responsible for sensing the electromotive force, while the converter converts the electromotive force into readable flow data.

Data transmission plays a crucial role in the electromagnetic flowmeter system. Whether it is on-site monitoring, remote control, or data analysis, stable and reliable data transmission is the foundation for ensuring the normal operation of the system. Once data transmission malfunctions, it may lead to measurement errors, production interruptions, or even safety accidents.
