Description

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.

Core Advantages
  • Stable signal without alternating interference: The output is direct current potential, and the signal processing circuit is relatively simple, not affected by power frequency interference.
  • No eddy current thermal effect: When measuring liquid metals, no heat is generated inside the metal pipe and fluid due to alternating magnetic fields, which is energy-saving and safe.
  • High-temperature and radiation-resistant design: Specifically designed for extreme working conditions, with a robust structure.
  • Can measure low-conductivity liquid metals: The requirement for conductivity is lower than that of the AC excitation method.
Comparison with modern mainstream excitation methods
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 For conventional industrial measurements, they have long been replaced by more advanced technologies suchs as low-frequency rectangular wave excitation due to their inability to overcome the fundamental obstacle of "polarization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".
