Have you ever wondered what the third most common flow meter is? For instance, the one that is behind the differential pressure? Flow measurement is the quantification of bulk fluid movement. It can be measured in different ways.
One way is by a mag flow meter. It is also known as a mag meter. The physical principle at work is electromagnetic induction. It requires a conducting fluid, for example, water that contains ions, an electrical insulating pipe surface, like a rubber-lined steel tube.
