1. What are Electromagnetic Flow Meters?
Electromagnetic flow meters, also called mag meters or magnetic meters, are volumetric flow meters which do not have any moving parts to wear, reducing the need for maintenance or replacement. Accuracy over a wide flow range can be as good as ± 0.5% of flow rate or better.

They feature an obstruction-free design which eliminates flow impediment, and operate with electrodes embedded on opposite sides of the flow tube or sensor to pick up the signal. Mag meters perform extremely well in many municipal and processing applications, and have become the meter of choice for measuring conductive liquids such as water or slurry.

2. Advantages And Disadvantage Electromagnetic Flow Meters

There are numerous benefits to using electromagnetic flowmeters to perform fluid flow measurements. They are generally non-invasive and have no moving parts, reducing the risk of breakdowns and the frequency of repairs. A decrease in flowmeter pressure is also usually no greater than that of an equivalent pipe length, reducing the piping costs. Some of the other major advantages provided by magnetic flowmeters include:

• Power usage is relatively low, with electrical power requirements as low as 15 watts for some models.
• They are mechanically obstructionless and can be equipped with abrasion-resistant liners, making them effective for measuring slurries and other erosive fluids.
• They are capable of dealing with most kinds of acids and bases, as well as water and water-based solutions, due to lining materials that are both insulators and have corrosion resistance.
• Relatively small amounts of electrode metals are needed for magnetic flowmeters.
• They can measure both very low flows and very high volume flow rates, with a minimum diameter of roughly 0.125 inches and a maximum volume of up to 10 cubic feet.
• They can usually measure multidirectional flow, either upstream or downstream.

Despite these advantages, magnetic flowmeters also present certain difficulties for flow rate measurement. These flowmeters are only effective on conductive fluids, and materials such as unmixed hydrocarbons and gases cannot be measured. However, magnetic materials themselves may also present problems, as hydrodynamic effects can alter the normal flow pattern and disturb the velocity rate enough to interfere with operations. Depending on their size and capacity, magnetic flowmeters can be relatively heavy, and those with higher corrosion and abrasion resistance can be expensive.

3. How to select and install a magnetic flow meter?

The key questions which need to be answered before selecting a magnetic flow meter are:

• Is the fluid conductive or water based?
• Is the fluid or slurry abrasive?
• Do you require an integral display or remote display?
• Do you require an analog output?
• What is the minimum and maximum flow rate for the flow meter?
• What is the minimum and maximum process pressure?
• What is the minimum and maximum process temperature?
• Is the fluid chemically compatible with the flow meter wetted parts?
• What is the size of the pipe?
• Is the pipe always full?

4. In-Line Magnetic Flow Meters installation Considerations

In-line flow meters do not require as much straight pipe as the insertion styles. A minimum of 5 to 10 pipe diameters of straight run upstream and 1 to 2 diameters downstream is recommended. In vertical pipe runs, flow should always run up and not down. These flow meters are very sensitive to air bubbles. The magnetic flow meter cannot distinguish entrained air from the process fluid; therefore, air bubbles will cause the mag flow meter to read high.
