Electromagnetic Water
Flow Meters
Overview
Our electromagnetic flow meters utilize advanced technology for precise fluid measurement in various industrial applications. These meters offer reliable performance with no moving parts and minimal maintenance requirements.
Measuring Principle: Based on Faraday's Law of electromagnetic induction, these meters are ideal for conductive water-based liquids but not suitable for oils, distilled water, or pure alcohol.
M9xx Series Features
- Faraday's Law: Based on electromagnetic induction where conductive fluid flowing through a magnetic field induces proportional voltage
- No Moving Parts: Design eliminates mechanical restrictions, resulting in minimal pressure drop and maintenance
- Robust Construction: High-quality, corrosion-resistant materials for harsh environments like mining sites and coastal installations
