ABB FEP300 Electromagnetic Flowmeter: Smart, Simple, and Built for the Real World

Let’s face it—sometimes you don’t need a flowmeter with every bell and whistle known to mankind. Sometimes you need something that just works, is easy to set up, and doesn’t require a engineering degree to configure. That is exactly where the ABB FEP300 Electromagnetic flowmeter fits in.

Here at ST-YUKE CO., LIMITED, we have helped customers across chemical plants, water treatment facilities, and food processing lines get this meter installed and running without headaches. The FEP300 is ABB’s “get it done” solution—all the core functionality you need, packaged in a reliable, affordable, and surprisingly clever device -1. Let’s walk through why this might be the perfect fit for your next project.

What Makes the FEP300 Special?

The FEP300 is ABB’s ProcessMaster standard version. Think of it as the sensible choice. It gives you the industry’s widest range of liners, electrodes, and sizes -1—so you can match it to whatever fluid you are pumping—but it strips away the complexity that sometimes comes with high-end instruments.

The philosophy here is simple: base functionality, short delivery times, and documentation that actually makes sense -1. No fluff. No features you will never use. Just solid flow measurement.

Technical Specifications: The Numbers That Count

Here is the data you came for. Straight from the ABB datasheets.

Sizing: From Tiny to Massive

The FEP300 covers an absolutely insane range of pipe sizes -1-2:

Nominal diameter: DN 3 to 2000 (1/10 to 80 inches)

That means you can measure flow in a 3mm lab line or an 80-inch main water pipe with the same model family. For most industrial applications, the sweet spot is DN15 through DN300, but knowing ABB, they have you covered if you need something outside that range.

Accuracy That Won’t Cost You

Depending on your application, you have options -1-2:

Standard accuracy: 0.4% of rate

Optional accuracy: 0.2% of rate

Some third-party listings also mention 0.3% as an option -4-10. For most water, chemical, and general industrial applications, 0.4% is perfectly adequate. If you are doing batching or custody transfer, spring for the 0.2% option. Either way, you are getting reliable data you can trust.

Pressure Ratings: Built for Industrial Lines

The FEP300 handles serious pressure -1-2:

PN 10 to 100 (depending on size and flange rating)

ASME CL 150, 300, 600, 900, 1500, 2500

That last one—2500—is serious business. If you are working in high-pressure applications, this meter can handle it.

Temperature Range: What Fluids Can You Measure?

Fluid temperature -3-5-8:

-25 °F to 130 °F (-32 °C to 54 °C) according to some sources

However, with the right lining choices, you can handle higher temperatures. The key is matching the lining to your process.

Linings: Match the Meter to Your Fluid

This is where electromagnetic flowmeters shine compared to other technologies. No moving parts, and the lining protects the meter from whatever you are pumping. The FEP300 offers -1-2-6:

Hard rubber — for abrasive slurries and general water duty

Soft rubber — general purpose

PTFE — for aggressive chemicals and higher temperatures

PFA — for ultra-pure applications and aggressive chemicals

ETFE — excellent chemical resistance

Linatex — natural rubber for abrasive slurries

Electrodes: Choose Your Weapon

You also get choices on electrode materials depending on your fluid compatibility. Standard options include stainless steel, Hastelloy, tantalum, platinum, and titanium. If you are moving aggressive acids, you probably want tantalum or Hastelloy.

Enclosure Rating: Wet or Dry

IP67 — Dust-tight and temporary immersion -4

IP65 also mentioned in some sources -4

If your meter lives outdoors or in a washdown area, these ratings keep the electronics safe.

Outputs and Communication: Talk to Your PLC

The FEP300 speaks the languages modern plants understand -1-2-6.

Communication Protocols

HART 7.1 — the industry standard

PROFIBUS PA

FOUNDATION Fieldbus

These are the big three. Whatever control system you are running, one of these will work.

Power Supply

Multiple options to fit your panel -4-10:

100 … 230 V AC (-15 / +10%)

24 V AC (-30 / +10%)

24 V DC (-30 / +30%)

Smart Features That Make Life Easier

Through-Glass Configuration

This is one of those “why didn’t everyone think of this” features. The FEP300 has capacitive keys that work right through the glass display window -1-2-4. You can configure the meter or check readings without opening the housing. In wet environments, dusty areas, or hazardous locations, that is a huge win. No need to break the seal, no risk of contamination, no tools required.

Easy Set-Up Function

ABB built in a simplified configuration routine -1-2-4. It walks you through the essential parameters and gets you up and running fast. For routine installations, you can be done in minutes rather than hours.

State-of-the-Art Memory Technology

Here is a scenario every instrument tech dreads: the transmitter dies, and you realize the configuration parameters were never backed up. Or they were backed up, but the file is on some retired engineer’s laptop.

The FEP300 solves this -1-2-4. All the critical configuration data is stored in the sensor head. If the transmitter ever fails, you swap in a new one, plug it in, and it auto-configures. No laptop. No manual re-entry. No downtime while you hunt for the original settings.

Diagnostics for Real-Life Situations

The FEP300 continuously monitors what is happening in your pipe -1-2-4. It detects:

Empty pipe or partially filled conditions -1-2-6

Other process anomalies

When something goes wrong, it displays status messages in accordance with NAMUR standards -1-2-4. And here is the best part—it shows help texts right on the LCD display -1-2-4. No cryptic error codes that force you to dig out the manual. Just plain text telling you what happened.

ScanMaster In-Situ Verification

You do not want to pull a meter just to check if it is healthy. The ScanMaster software option -1-2-4 lets you perform verification right in the field, with the meter still in the pipe. It checks the integrity of the flowmeter and the installation. If everything is good, you move on. If something is drifting, you catch it before it becomes a problem.

Unparalleled Serviceability

ABB thought about maintenance when they designed this thing -4-10:

Fault finding help texts in the display guide you through troubleshooting

Replaceable electronics cartridge minimizes downtime—swap it and go

Universal transmitter reduces spare parts inventory costs

That last one is a big deal for plants with multiple flowmeters. One transmitter design fits many sensors. Stock one spare instead of ten.

Installation: What You Need to Know

Electromagnetic flowmeters are different from other technologies. They need the pipe to be full, and they care about grounding.

Straight Runs

The FEP300 is independent of flow profile as long as there are no standing vortices reaching the measuring zone. For most installations, standard straight run recommendations apply. If you are installing for calibration or reference conditions, follow the manual. But for everyday industrial use, common sense positioning usually works.

Grounding

This is critical. The sensor must be connected to earth potential, and ideally that potential matches the potential of the measuring medium. For plastic pipes or pipes with insulating linings, you need grounding rings or electrodes.

Mounting Position

You can mount it horizontally or vertically, but:

Keep the electrodes in the horizontal plane (not at the top or bottom) to avoid air bubbles or sediment messing with your signal

For vertical installation, flow direction should be upward to keep the pipe full

Avoid mounting at the highest point of the system where gas can collect

Process Connections

The FEP300 supports multiple flange standards -1-2-6:

DIN 2501 / EN 1092-1

ASME B16.5 / B16.47

JIS

AS2129

Whatever your regional standard, ABB probably has a flange option.

Hazardous Area Approvals

If you are in oil and gas or chemical processing, you probably need Ex approvals. The FEP300 has you covered -1-2-3:

ATEX for Europe

IECEx international

FM / cFM for North America

NEPSI for China

GOST for Russia
