Buyer guide: CoriolisMaster FCB450 vs Micro Motion 5700

Today we’ll check out a couple of popular Coriolis meters on the market, Emerson’s Micro Motion 5700 and ABB’s CoriolisMaster FCB450! You know these two companies, but have you seen these devices yet? Even if you have, you might still learn a thing or two here, so come on in!

ABB CoriolisMaster FCB450

In the instrumentation realm, ABB covers plenty of territory with its robust product portfolio. So you ready to review the CoriolisMaster FCB450 ? Then let’s go!


The FCB450 has a fairly simple, intuitive design. After all, good engineering has more to with smooth operation than fancy looks. And this product aims to improve the user’s experience, so good job, ABB!

It has a good accuracy for liquids at  0.1 percent for mass, about  0.15 percent for volume, and around  0.002 kilogram per liter (kg/l) for density. Plus, the advanced version of the FCB450 can yield a result of 0.001 kg/l for density. Better yet, if you perform the field calibration, then you can get precision up to 0.0005 kg/l!

ABB could’ve focused a bit more on materials, though. The FCB450 lags behind the market here, with just stainless steel and nickel alloy. If you need another type, then several other brands offer a better range of materials.


Of course every flow device should have good range as well as accuracy. The FCB450 goes from half an inch to six inches, which puts it on the decent side. And its easy setup and configuration can get your meter up and running in a jiffy! Plus its compact size and self-draining design make installation and maintenance easier.

On the other hand, it doesn’t do much for seamless integration, with just analog, pulse, frequency, or switch output. Nope, no FOUNDATION Fieldbus (FF), PROFIBUS PA/DP, Modbus, or Ethernet-IP. The primitive protocols drag this device back to the caveman timeline.


ABB has an online tool to scale out the meter with your process conditions so you can compare its potential performance against other devices on the market.

And the VeriMass feature on the FCB450 lets you to check the device’s condition. It can also thoroughly test the device, sensor, electronics, and more. This feature can help you diagnose and fix issues as well as keep issues from cropping up. Then the FillMass option can help you control fill in an application.

In general, the FCB450 may serve you well, depending on your application. And it does offer more than a regular user might expect!

Micro Motion 5700

Yet another Emerson product! But does it feel like true Emerson. Let’s have a look at the Micro Motion 5700’s parameters and draw our conclusions.


Most of the developments showcased on the new Micro Motion 5700 revolve around its transmission capability. It offers a wide range of digital protocols and methods to access intel.

And like many other Emerson devices, the 5700 has a sound design and lots of attributes to enhance a user’s experience.


First up, protocols. The 5700 offers EtherNet-IP, PROFINET, and Modbus TCP/IP – even built-in Ethernet. Nice, huh? Better yet, you can save and upgrade the configuration and diagnostics  through a USB stick! No USB-C, though. We really hope Emerson brings this option in the next version.

Emerson has also done decent work on making the user-friendly display easy to set up and handle. Although the familiar aspect of it makes the device easier to understand, it means that it doesn’t offer anything new either.


The 5700 can work in a variety of applications. However, it has a lot of competitors, such as the Promass 300 and Promass 500 from Endress+Hauser, which might make choosing difficult.

Compared to other products in the market, the Micro Motion 5700 may chew through more of your wallet. So make sure you do your due diligence before hitting “buy” at checkout!

Table of comparison


Micro Motion 5700

CoriolisMaster FCB450




new user-friendly design, improved display, easy cable connection

familiar design with strong features



Supported protocol

HART, FF, EtherNet-IP, and more, but no PROFIBUS

analog, pulse, frequency, or switch output



Sensor options

enough sensors to offer a range of wetted materials, like stainless steel, nickel alloy, and super duplex

two sensors, FCB and FCH for hygienic processes; only stainless steel and nickel alloy for materials




F-series sensor offers 0.1 percent in mass and 0.1 percent in volume; gas gets 0.5 percent and density around 0.0005 grams per cubic centimeter

0.1 percent in mass, 0.15 percent in volume; standard accuracy of 0.002 kg/l in density and up to 0.0005 with field calibration



General information and documentation

easy-to-find  documentation, decent mobile experience; blog, videos, and forums

so-so site and mobile version,  could provide more info on devices



Special features

SMART meter verification; needs AMS suite with snap-on or PROLINK software for full access

VeriMass can check conditions and run diagnostics on electronics, sensors, outputs, and configurations



The Micro Motion 5700 looks a tad better on the table, but only on a quantitative level. Consequently, both these devices could serve you well, depending on your needs. Emerson brings innovation with the 5700 and sensors like the Elite, but ABB holds its own with strong features and good design with the FCB450.

So which one looks good for your process?
