One way to understand the way that electromagnetic flow meters work is by considering Faraday’s Law of electromagnetic induction. Faraday’s Law states that, as it moves at right angles through a magnetic field, the voltage produced by a conductor is proportional to its (the conductor’s) velocity. Read More…

These flow meters only work with conductive and water-based fluids. They’re ideal for measuring flow rate of dirty liquids. However, they can work with a wide range of fluids; in fact, they are widely considered the third most common type of flowmeter. This is largely due to the fact that they have no moving parts, which means that they require less maintenance, and tend to last longer.
Because electromagnetic flow meters can only be used with conductive, water-based fluids, before making the decision to purchase one, ask yourself the following questions about your application: Does my application used conductive fluid? Is my application fluid abrasive? What is the minimum and maximum flow rate of my application? Is my pipe always full?
Even if you ask yourself all the right questions, the only way to know without a doubt that this type of flow meter is right for you is by talking over your application with an experienced flow meter manufacturer. In fact, a good manufacturer, like one of those we have listed on this site, will be able to provide you with a custom flow meter, if you wish.
