A magnetic flow meter, also referred to as mag flow meter or magmeter, is a volumetric flow meter that measures liquids or liquid slurries that have a minimum conductivity of 5 µS/cm.
Magnetic flow meters will typically not work with hydrocarbons, distilled water, non-aqueous solutions and non-conductive solutions.
Typical Industries Where Magnetic Flow Meters are Used
- Water / Wastewater Industry
- Food and Beverage
- Metals
- Brewing, Distilling, and Wine makening
- HVAC
- Chemical
- Pulp and Paper
- Pharmaceutical
- Mining, Mineral Processing
Application area
1. Drinking water supply, water supply, reservoir and pumping station etc.
2. Chemical acid, lye, conductive solution, cooling fluid, additives etc.
3. Drink water, beer, wine, alcohol, milk, yogurt, fruit juice, syrup, blood etc.
4. Refrigeration / air conditioning and refrigeration thermal measurement, or heat energy.
5. Sewage, industrial sewage discharge, sewage etc.
6.Control of metal industrial pump,cooling water and the flow of water.
7. The textile industry of water, pigments, chemicals, bleaching chemicals etc.
Magnetic flow meters require a minimum medium conductivity for the technology to measure flow. This chart provides a general guideline on conductivity of common media
