电磁流量计工作原理是基于法拉第电磁感应定律。即：导电液体在磁场中作切割磁力线运动时，在垂直于流速向量和磁场向量的方向上就会产生感应电动势，感应电动势与流量成正比，经过处理运算后，进行瞬时流量和累积流量的计量。
应用领域：
• 水及污水处理：进水管路、出水管路、污泥管路等
-
- 4-electrode measurement system: Measuring electrode, reference electrode, and empty pipe detection electrode.
- No moving parts or pressure loss in the measuring tube.
- Measurement results are independent of physical parameters such as liquid density, viscosity, temperature, pressure, and conductivity (not less than 5 μS/cm).
- Bidirectional measurement system with three built-in calculators: forward total, reverse total, and difference total.
- Available with different linings and electrode materials for excellent wear resistance or corrosion resistance.
- Unique anti-interference filter circuit and processor ensure stable output.
- Fast response speed with multi-range settings.
- Highly integrated converter with multiple functions, including fault alarms, self-diagnostics, and low-signal cut-off.
- Adjustable pulse output width.
- Equipped with a grounding electrode.
- Rich and vivid LCD display shows extensive information, including instantaneous flow and cumulative flow. The measurement system is designed with vibration and electromagnetic interference resistance.
- Optional communication protocols: HART, RS485 (MODBUS), Profibus DP, and more.
