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.
