Every plant strives for maximum efficiency by controlling its processes, and flow measurement is crucial to achieve this goal. So today, we’ll talk about how compact magnetic flow meters can help.
Of course, to select the proper flow meter for your process, you must keep in mind three things: your product, its flow rate, and the space the meter will occupy. So if you have to measure flow in a small place, then try a compact magnetic flow meter!
Magnetic flow meters depend on Faraday’s law of electromagnetic induction. If you want to learn more about this working principle, then take a quick look at our main article on magmeters.
Why a compact magnetic flow meter?
In a confined space or rough environment (or both), a compact magnetic flow meter doesn’t need the upstream and downstream straight runs that other devices do. Therefore it becomes our first choice.
You can find these meters in drinking water applications and other similar processes.
Pros and cons of magnetic flow meters
- No moving parts
- No pressure loss
- Good turndown (20: 1)
- Good measurement of slurry or water
- Not suitable for nonconductive liquids
- Limited installation options
- Not suitable in vacuum or high temperatures
- Poor measurement of gases
You can get compact magnetic flow meters in a handful of materials and sizes to work in applications such as the following:
- Cooling circuits for heated equipment
- Secondary circuits for drinking water
- Cooling processes for tunnel boring machines
- Food processes that use heated/cooled water (double jacket needed)
- Container sanitation for food and beverages
- Paint in ceramic industries
- Water quality stations
- Clean-in-place (CIP) systems to monitor return flow
- Industrial furnaces
- Public swimming pools
Innovations in compact magnetic flow meters
So now you know that these meters work well in many industries. However, you’ll always find room for innovation. Some suppliers have already added useful features to their products, such as the Picomag from Endress+Hauser, LFE series from SMC, and MIM from Kobold.
Take a look at some of the new ideas now on the market:
- Multivariable monitoring
- Bluetooth (within 10 meters)
- IO link for Fieldbus systems
- Plug-and-play functionality
- Corrosion-resistant materials
- Knock functionality (tap the device itself to change settings)
- Auto-rotating display
Compact magnetic flow meters can take on difficult conditions in a multitude of applications. And as technology improves, they can go a long way toward helping you achieve peak efficiency in your plant.
