A Magnetic Flow Meter (Mag Meter) is a volumetric flow meter that uses Faraday’s Law of Induction to measure conductive liquids (water, acids, slurries).
Because they have no moving parts and a full-bore design, they are the industry standard for Wastewater, Palm Oil Effluent (POME), and Chemical Dosing.
Installation Rules (5D/3D) Mag meters require a calm flow profile.
- Upstream: Minimum 5x Diameter straight pipe.
- Downstream: Minimum 2x Diameter straight pipe.
- Position: Always install on a vertical pipe flowing UP (to ensure the pipe is full) or a horizontal pipe at the lowest point.
To get an accurate reading, the fluid must be grounded.
Metal Pipes: You can usually ground the meter to the pipe flanges directly.
Plastic / Lined Pipes: You MUST use Grounding Rings or a Grounding Electrode. Without this, your reading will be unstable.
💡 Expert Tip: For Chemical applications, always use Hastelloy C electrodes. For standard Water, 316 Stainless Steel is sufficient.
For General Water: Yokogawa ADMAG AXG Series (The industry standard).
For Chemical/Sanitary: Anderson-Negele IZMAG (For Food & Pharma).
For Remote Areas: [Battery Powered Mag Meter] (Perfect for irrigation).
