Working Principle
Based on Faraday's law of electromagnetic induction, the flowmeter operates by detecting electrodes installed perpendicular to both the tube axis and magnetic lines. As conductive liquid flows through the measurement tube, it cuts magnetic lines, generating an induced electromotive force proportional to flow velocity.
E = KBVD
Where:
E - Induced electromotive force
K - Magnetic field distribution coefficient
B - Magnetic induction strength
V - Average liquid velocity
D - Electrode distance (tube diameter)
Where:

B - Magnetic induction strength
V - Average liquid velocity
D - Electrode distance (tube diameter)
Key Features
- Simple sensor structure with no moving parts for unobstructed fluid flow
- Capable of measuring dirty, corrosive, and suspended solid-liquid media
- Accuracy unaffected by temperature, viscosity, density, or conductivity variations
- Output proportional only to average velocity, independent of flow profile
- Fast response with no mechanical inertia, suitable for pulsating flow
- Bidirectional flow measurement capability
- Wide size range from DN3 to DN3000mm
Applications
Water supply systems, chemical processing, coal industry, environmental protection, light industry, metallurgy, paper manufacturing, and other industries requiring precise conductive liquid flow measurement.
