Understanding The Magnetic Flow Meter Theory

Technology is a wonderful aspect as it develops machines that assist man in his daily activities. In industries, measurements need to be put in place. For this reason, individuals have to take control and manipulate such situations. Fortunately, the magnetic flow meter theory was developed to create meters that play a great role in many service industries.

The meters work using a number of principles. On the other hand, before highlighting them, there is a need to know what these gadgets do and what they are. A magnetic flow meter is volumetric and compact. This means that it has no moving parts that require lubrication or constant servicing. It is useful in water, chemical and other sectors that facilitate the flow of conductive fluids. Generally, hydrocarbon components, water that has been distilled and non-aqueous solutions do not work. These devices are economical due to low maintenance fee and useful in areas where pressure fluctuations are common.

Operation principle

The theories behind creation of the magnetic meters rely entirely on physics. Actually, the Faradays law is the main pillar. It states that, the velocity of a conductor is directly proportional to a voltage induced to the conductor moving at a right angle through a magnetic field.

This theory is supported by a mathematical formula:
E is directly proportional to D*V*B

E represents voltage in the conductor
V is the velocity of conductor
D is the length of conducting pipe
B represents the strength of magnetic field

However, a magnetic meter can only apply the above principle if the fluid being measured can conduct electricity.

Factors to consider before selecting ideal meters

In order to select ideal gadgets for measurements, the buyer should have some little knowledge on some characteristics. Foe example, the velocity of conductors is determined by the diameter of the pipe. Therefore, in cases where higher velocities and pressure are required, smaller diameters should be used.

The conductive fluid to be used should be known. If it is corrosive, then meters made from abrasion resistant materials are ideal. In addition, the meters should be sensitive and sense presence or absence of the fluid. This way, measurements can be taken throughout.

The magnetic flow meter theory has created room for more improvements. Based on this principle, manufacturers come up with better versions of these gadgets by improvising different concepts. In future, only the best meters will be in use.
