MDR-3200-EMF 电磁流量计

MDR-3200-EMF 电磁流量计工作原理/Electromagnetic Flow Meter working principle：

MDR-3200-EMF 电磁流量计的核心原理基于法拉第电磁感应定律。当导电液体通过磁场时，会产生与流速成正比的感应电动势。电磁流量计通过测量这一电动势，即可计算出流体的流量。具体来说，电磁流量计由励磁线圈、测量电极、衬里和传感器等部分组成。励磁线圈产生交变磁场，流体中的导电颗粒在磁场作用下切割磁力线，从而在测量电极之间产生电压信号。通过对电压信号的采集和处理，可以计算出流体的瞬时流量和累积流量。

The core principle of the MDR - 3200 - EMF electromagnetic flowmeter is based on Faraday's law of electromagnetic induction. When a conductive liquid passes through a magnetic field, an induced electromotive force proportional to the flow velocity is generated. The electromagnetic flowmeter calculates the flow rate of the fluid by measuring this electromotive force. Specifically, the electromagnetic flowmeter consists of components such as an excitation coil, measuring electrodes, a liner, and a sensor. The excitation coil generates an alternating magnetic field. The conductive particles in the fluid cut the magnetic field lines under the action of the magnetic field, thus generating a voltage signal between the measuring electrodes. By collecting and processing the voltage signal, the instantaneous flow rate and cumulative flow rate of the fluid can be calculated
