Applicable Liquid Metal Signal-Stabilized DC Electromagnetic Flowmeter
DC electromagnetic flowmeter refers to an electromagnetic flowmeter that excites the excitation coil with a constant DC current or a unidirectional pulse current.
| Characteristics | (Pure) DC excitation flowmeter | Modern low-frequency rectangular wave excitation flowmeter |
|---|---|---|
| Excitation waveform | Constant DC or unidirectional long pulse. | Alternating positive and negative rectangular waves (typical frequencies such as 6.25Hz, 12.5Hz). |
| Applicable medium | Non-electrolyte: mainly liquid metals. | Electrolyte: water, acid, alkali, slurry, and all conventional conductive fluids. |
| Polarization effect | No effect on liquid metals. | Effective elimination of polarization voltage influence through rapid magnetic field reversal. |
| Zero stability | Poor, complex compensation required. | Excellent, modern intelligent transmitters can achieve automatic zero tracking and correction. |
| Resistance to power frequency interference | Immune by nature. | Effective suppression through techniques such as synchronous sampling. |
| Main application fields | Nuclear industry, advanced metallurgy. | All common industrial processes (water treatment, chemical, food, etc.). |
DC electromagnetic flowmeters represent the origin of electromagnetic flowmeter technology and a special technical path. For conventional industrial measurements, they have long been replaced by more advanced technologies suchs as low-frequency rectangular wave excitation due to their inability to overcome the fundamental obstacle of "polarization effect".
