Flowmeter Flow Meter
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 & 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.
