Electromagnetic Flow Meters

Electromagnetic flow meters, often referred to as simply magnetic flow meters or even mag meters, are devices that are used in a wide range of applications in order to determine the rate of flow of a substance.

Electromagnetic flow meters fall under the volumetric category of flow meters and are ideal for applications that contain dirty liquids that are conductive and are water based.

They are often seen as the third most common type of flowmeter thanks to the fact that they have no moving parts, providing a longer lifespan, and they are able to work with a wide range of fluids.Read More…Request for Quote

These flow meters operate using quite a simple concept. A magnetic field is applied to the metering tube, creating a potential different which is proportional to the velocity of the flow of the liquid within the tube. The operation of these meters can be explained through the use of Faraday’s Law which states that the voltage induced across a conductor as it moves at right angles through a magnetic field is proportional to the velocity of that conductor.

So to put it in terms that relate to flow meters, electromagnetic flow meters utilize signal voltage in order to determine the velocity, and thus the rate of flow, of the conductor, in this case the fluid. This is why it is so important that the fluid is conductive and water based. There are quite a few questions to ask yourself about your application before purchasing an electromagnetic flow meter such as: is the fluid in my application conductive? Is the fluid abrasive? What is the minimum and maximum flow rate of my application? Is my pipe always full?

There are many other questions that play an important part in finding the right magnetic flow meter for your application. This is why it is a great idea to consult with a knowledgeable flow meter manufacturer.

They can help assess your application and provide a solution that fit the unique specifications and needs of your applications. Having the right flow meter is important, as purchasing a flow meter that is not ideal to your application can result in a loss in efficiency, loss of time and most importantly a loss in finances.
