ABB FCH450 Coriolis Mass Flowmeter: The Ultimate Hygienic Precision Instrument

If you are working in food and beverage, dairy, pharmaceutical, or personal care production, you already know the challenge. You need flow measurement that is accurate, but you also need equipment that meets strict hygienic standards and can survive aggressive cleaning cycles. The ABB FCH450 Coriolis mass flowmeter is the premium solution in ABB’s hygienic FCH400 series—and here at ST-YUKE CO., LIMITED, we have helped numerous customers make the decision to invest in this top-tier instrument.

Why choose the FCH450 over the FCH430? Because sometimes you need that extra level of precision. Sometimes you need built-in concentration software that replaces lab samples with real-time data. Let’s dive into what makes the FCH450 worth the investment.

What Makes the FCH450 Different from the FCH430?

The FCH430 is a solid hygienic workhorse. But the FCH450 takes everything to the next level. Same compact, EHEDG-certified design -1. Same ability to install in tight spaces with no upstream or downstream straight pipe requirements -1. Same polished stainless steel 316L wetted parts -1.

The difference comes down to two things: accuracy and intelligence -1.

The FCH450 comes with two software packages that completely transform what you can do with the meter:

DensiMass software: For high-accuracy direct concentration measurement -1

FillMass software: For filling application control with integrated pre-counter and overfill correction -1

Technical Specifications: The Numbers That Matter

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

Available Sizes and Flow Ranges

The FCH450 covers the standard hygienic line sizes that matter for food, beverage, and pharma applications -1-2:

DN 25 (1 inch): 0 to 35,000 kg/h (77,162 lb/h)

DN 50 (2 inches): 0 to 90,000 kg/h (198,416 lb/h)

DN 80 (3 inches): 0 to 250,000 kg/h (551,156 lb/h)

Accuracy: Where the FCH450 Truly Shines

This is the headline feature. Compare this to the FCH430’s 0.4% or 0.25% accuracy -1:

Mass flow accuracy (liquids): 0.15% or 0.1% of rate -1-2

Volume flow accuracy: 0.15% of rate -1-2

Density accuracy: 2 g/l or 1 g/l depending on calibration -1-2

That density accuracy is what gets people excited. At 1 g/l resolution, you can detect minor variations in product concentration that would be invisible to a standard meter -1. For applications like Brix in beverages, Plato in brewing, or API gravity in edible oils, this replaces lab sampling with continuous inline measurement -4.

Temperature Handling

The FCH450 handles higher temperatures than the FCH430, giving you more headroom for demanding processes -1:

Process temperature range: -50 °C to 205 °C (-58 °F to 400 °F) -1-2

That extra range matters for SIP (sterilize-in-place) cycles and high-temperature hygienic processes.

Wetted Materials

All contact surfaces are polished stainless steel, meeting the strictest hygienic standards -1:

1.4404 / 1.4435 (316L) — FDA compliant, EHEDG certified for cleanability -1-2

Ambient Conditions

The electronics are built to survive tough processing environments -1:

Ambient temperature rating: Designed for 70 °C (158 °F) -1

Vibration resistance: Handles high vibration environments without flinching -1

Enclosure rating: IP 65/67 (NEMA 4X)—dust-tight and hose-down proof -1

Pressure Drop: The Hidden Savings

Here is a stat that surprises a lot of engineers. The FCH400 series features a redesigned inner tube that drops pressure loss significantly compared to some other meters -1. Lower pressure drop means your pump doesn’t work as hard. Over a year of continuous operation, that adds up to real energy savings.

The Software Advantage: DensiMass and FillMass

Let’s dig deeper into those two software packages, because this is what you are really paying for when you step up to the FCH450 -1.

DensiMass: Concentration Measurement Made Simple

DensiMass lets the transmitter calculate the concentration of a mixture based on measured density and temperature -1. It handles:

Pre-set concentration matrices—think Brix, Plato, Baume, API gravity

Custom matrices with up to 100 values for your specific products

For industries like beverage production, dairy processing, or edible oils, this means -4:

Real-time product quality verification without waiting for lab results

Immediate adjustments to maintain consistency

Reduced product giveaway

FillMass: Precision Filling and Batching

FillMass is built for applications where every milliliter counts -1. It includes:

Integrated pre-counter for accurate batch totals

Overfill and underfill correction — automatically compensates for variations

Contact output for valve control — triggers the valve to close at exactly the right moment

ABB designed this for filling processes. If you are filling bottles, drums, or IBC totes, FillMass turns the flowmeter into a batch controller. No separate PLC needed for basic filling operations -1.

Outputs and Communication: Talk to Any PLC

The FCH450 is built for integration. It speaks the languages modern plants understand -1.

Modular I/O

You get 5 modular I/Os -1-2. That means you can configure exactly what you need:

Analog outputs (4-20 mA)

Digital outputs (pulse, frequency, or binary)

Digital inputs

Communication Protocols

Choose the protocol that fits your control system -1:

HART 7.1 — standard

PROFIBUS DP

Modbus (RS485)

Ethernet options: Ethernet/IP, Modbus TCP

Webserver built-in for direct browser access -1

Power Supply

Multiple options to fit your panel -1:

DC: 11 to 30 V DC

AC: 110/230 V AC

Power over Ethernet available -1

Smart Features You Will Actually Use

VeriMass On-Board Verification

You do not want to pull a meter just to check if it is healthy. VeriMass runs diagnostics to check for erosion, corrosion, or sensor damage -1. It gives you confidence that your 0.1% readings are still valid without sending the unit to a calibration lab -1.

The system continuously checks the sensor and electronics. If something goes wrong, it logs the fault with a timestamp and a plain-text description -1. No cryptic error codes.

There is also a trending analysis function that watches the meter’s performance over time -1. If it starts drifting outside calibration range, you will know before it becomes a problem. That means you only pull the meter when you actually need to—not on a fixed schedule that wastes time and money.

SmartSensor Technology

All the meter intelligence is located in the sensor head itself -1. This means:

Installation flexibility — transmitter can be integral or remote -1

Digital signal transmission between sensor and electronics for better noise immunity

Future-proof design

SensorApplicationMemory

This is one of those features you do not appreciate until you need it -1. All the sensor data (calibration, configuration) is stored in the sensor head. If the electronics ever fail, you just swap the board. Plug it in, and it auto-configures. No laptop, no manual re-entry, no headaches -1.

Operation Through the Glass

The display has capacitive keys that work right through the glass window -1. You can configure the meter or check readings without opening the housing. In a wet environment or a cleanroom, that is a huge win for safety and contamination control -1.

Enhanced Coriolis Control (ECC)

For challenging fluids, the FCH450 offers an Enhanced Coriolis Control option -1. This improves measurement accuracy for multiphase conditions and other difficult fluids. If you are dealing with entrained gases or non-ideal process conditions, ECC helps keep you accurate -1.

Installation: No Straight Runs Required

Like all Coriolis meters, the FCH450 doesn’t care about upstream or downstream piping -1. Stick it where it fits. The compact design is perfect for OEM machine builders who need to cram everything into a small footprint -1.

Mounting Tips for Hygienic Lines

For liquids -1:

Mount vertically if you want guaranteed self-draining after CIP cycles -1

If mounting horizontally, orient the housing upward to prevent trapped air

Keep the tubes full—maintain back pressure to prevent gas bubbles

The measuring tubes must always be completely filled with fluid

For gases:

Vertical mounting is best to keep the tubes free of liquid

Install in an ascending pipe

Self-draining design -1:

The FCH450 is designed to drain completely—perfect for hygienic applications where product residue cannot be tolerated -1

Certifications You Can Trust

The FCH450 carries the stamps required for regulated industries -1:

EHEDG certified for hygienic design and cleanability -1-2

FDA compliant materials -1-2

ATEX and cFMus options for hazardous areas (zone 0/1/2 and Div 1/2) -1-2

NEPSI for China -1

MID/OIML R117 for legal metrology -1

So whether you are building a dairy skid for Europe or a pharmaceutical line for North America, this meter checks the boxes -1.
