ELECTROMAGNETIC FLOWMETER OPERATING PRINCIPLE

The SUP-LDG electromagnetic flow meter (magmeter) operates based on Faraday's Law of Electromagnetic Induction. When conductive liquid flows through the magnetic field generated by the meter's coils, it induces a voltage signal proportional to the flow velocity. This voltage is detected by electrodes and converted to precise flow rate measurements.

FREQUENTLY ASKED QUESTIONS - ELECTROMAGNETIC FLOWMETERS

Q: What is the minimum fluid conductivity required for accurate measurement? +

A: The SUP-LDG requires fluids with ≥5 μS/cm conductivity for stable measurement. For optimal performance, we recommend >20 μS/cm. Typical tap water ranges 50-800 μS/cm.

Q: What are the installation requirements for electromagnetic flow meters? +

A: Requires 5D upstream and 3D downstream straight pipe (D=pipe diameter). Works in any orientation but avoid top-down flow for gas-liquid mixtures. Must always run full in liquid applications.

Q: How do I select the right liner material for my application? +

A: Consider chemical compatibility, temperature, and abrasion:
- PTFE: Most chemicals <120°C
- PU: Abrasive slurries <60°C
- Neoprene: Low-cost water applications
Our engineers can provide material selection guidance.

Q: What maintenance is required for magmeters? +

A: Electromagnetic flow meters are virtually maintenance-free. Recommended checks:
- Annual electrode inspection (clean if coated)
- Verify grounding system integrity
- Calibration verification every 2-3 years
