[0002] Electromagnetic flowmeter is a commonly used flow measurement instrument with many excellent characteristics. Its working principle is mainly based on Faraday's law of electromagnetic induction for flow measurement. It has the characteristics of stable and reliable measurement, small pressure loss, low power consumption, multiple communication signal output and self-test and self-diagnosis functions.
