Why Use an Electromagnetic Flow Meter?

If only life was simple we would be able to measure the flow of any material in any situation using just one technology. In the real world we have to choose between a number of methods, each with advantages in certain applications but, equally, each with limitations which make it totally unsuitable in particular cases. However, of all those technologies, the electromagnetic flow meter can justifiably claim to be the most universally applicable.

Judged in terms of the number of applications and industries in which it has been successfully used, and the level of accuracy it achieves, the electromagnetic flow meter, or magmeter, is as close to being the universal answer as we have seen yet. It is estimated that around a fifth of all flow meters sold in the world are electromagnetic flow meters.

As well as their obvious applications in relation to water, from the perfectly clean to the dirtiest of wastewater, they can be found in use within the food and drink manufacturing, chemical processing and production, pharmaceutical and mineral extraction industries, to name but a few. They can measure flows of everything from weak solutions to the heaviest of slurries.

In many cases electromagnetic flow meters are specifically designed to cope with the particular demands of the industry and its materials. For example, special liners are used to prevent damage by corrosive or abrasive flows.

One huge advantage of magnetic flow meters is that their principle works on almost any diameter of pipeline, from half an inch (or even less) to 78 inches (or even more). I challenge you to find a flow rate method to equal that!

Electromagnetic flow meters are also very hard to beat when it comes to accuracy.

Last but not least, you should bear in mind that an electromagnetic flow meter is essentially very simple in structure, without moving parts, so once it’s installed you can expect it to continue working with little or no need for maintenance.
