Comparison: Micro Motion 2200S vs Promass F 200
Choosing the right flow meter for your application can prevent many problems, and one of the stars in this area is the Coriolis flow meter. If you want an accurate meter without inlet and outlet run requirements that provides more than just flow measurement, then you’d do well to get a Coriolis meter.
Usually, a flow meter is a four-wire transmitter, with a pair of cables for power and another pair for communication. However, a new generation of flow meter brings loop power to the show. These devices don’t need an external power supply, an advantage you’ll appreciate in a new application, where you don’t have a structure yet. Loop-powered flow meters can save money with installation, materials, and time, but they still have limitations, such as protocol choice and sensor size.
Today, we’re comparing two-wire Coriolis flow meters from a couple of big names in the market. Let’s sniff out the positives and negatives of both! On the right, Emerson Automation Solutions brings another product from its Micro Motion brand, the 2200S. On the left, the crew from Endress+Hauser offers their first Coriolis flow meter on review here, the Proline Promass F 200. Hope y’all are ready, because here we go!

The Micro Motion 2200S makes a good first impression, compact and decently designed – even pleasant, if I can say that about a transmitter! However, it has a smaller LCD than the Promass F 200, and the display only shows the process variable, units, and a few alarms. But if that’ll do for you, then why do you need more?
It gives you the option for local configuration, using the push buttons on the display. On the downside, you have to open the housing to get to the buttons, and it doesn’t have a touchscreen option. Nonetheless, it provides an acceptable user experience. Using the buttons to scroll and enter, you can soon navigate the configuration fairly well.
The Promass F 200 also makes a good first impression, with its clear design and big display. And it has a design similar to the radar level transmitter. Familiarity with the design means you won’t waste time learning how to use it. Good stuff, right?
But I really like the four-line illuminated display with its nifty graphics! You can choose what information you see, and it offers an excellent range of combinations and buttons on the display for local configuration. Plus, if you want a touchscreen, then you can pull that in as an option. Best of all, you don’t need to open the housing to access the buttons.
Speaking of access, the Micro Motion has the sensor directly integrated with the transmitter. If you have a remote third-party display, you can read the signal from the sensor, but the technical manual gives very little help for that. Endress+Hauser, on the other hand, provides a remote version of the Promass F 200, the FHX50, that you can use to set up remotely and check all your process values.
Measurement and sensors
Both flow meters have similar process measurements because they’re both Coriolis flow meters. Come on, what did you expect? But let’s see if they differ in the little details.
The Micro Motion 2200S can take three types of Emerson sensor, the ELITE, F-Series, and H-Series. The ELITE has the best performance and accuracy in the portfolio, the F-Series has a better price point, and the H-Series works for hygienic applications. We’ll use the ELITE sensor features for now, and later, we can compare the other sensors. The 2200S can measure mass and volume flow, temperature, and density.
Jumping to the Promass side, the F 200 can take two sensors from the Endress+Hauser portfolio, the F and the E sensors. The F offers more than the E, but if the E will take care of you, why not check it out? For now, we’ll stick with the F, as it compares better against the ELITE. Now, the Promass F 200 will measure mass flow, density, volume flow, corrected volume flow, and reference density. So both options offer good information from the field.
This is a delicate topic, because the Micro Motion 2200S falls way short here. First, it’s not really 4-20 milliamps (mA). Yeah! I know, right? It uses 12-20 mA, so if you want the standard 4-20, you need to install a barrier between the control system and the meter! Too complicated. Furthermore, it only has HART and the ability to connect a wirelessHART adapter. Pretty weak sauce.
The F 200 won’t need a converter to read the analog signal. It powers up from 18 to 35 volts, with the standard output of 4-20 mA. It also can communicate through HART, FOUNDATION Fieldbus (FF), and PROFIBUS PA. What can I say? Well done, E+H! Oh, almost forgot. It has other options available, such as pulse, frequency, and switch. Nice.
The Micro Motion 2200S can take sensors between a tenth of an inch to six inches in size. As for accuracy, in liquid an ELITE sensor gives you +-0.1 percent of rate, in gas +-0.35 percent of rate, and in density +-0.0005 grams per cubic centimeter (g/cm3)! Also, you can use it in temperatures from -240 to 204 degrees Celsius and pressures from 100 to 413 bar.
The F 200 allows sensor sizes from three-eighths to three inches. In liquid the mass and volume flow error is +-0.1 percent, in gas +-0.35 percent, and in density +-0.0005 g/cm3. It has a smaller temperature range than the 2200S, from -50 to 150 degrees Celsius, with an option for 205 degrees Celsius. And the pressure is PN100, Class60, and 63K. If you live in Russia, you know what that means, but we can say that they’re similar.
The Micro Motion 2200S provides a list of sensor diagnostics, so you can run the meter verification and find out the health of your sensor using the PROLINK, AMS Suite, or field communicator.
The F 200 has Endress+Hauser’s Heartbeat Technology. The Heartbeat Verification runs diagnostics through the display or field communicator to update you on the health of your devices. If you want more information in a proper report, you can use the FieldCare to print it out. The Heartbeat Monitor only reads the conditions of your sensor, which is okay.
The F 200 also has the HistoROM, an internal memory that can save configurations, which saves time when you need to do some replacing. Last but not least, the display can also back up configurations, then upload or download the data from a device to another.
Information and documentation
Nothing new here! But if you haven’t read our earlier reviews, I’ll summarize. Emerson has a responsive website, where you can easily find devices and documentation. It also has a bunch of blogs and such where they post a lot of articles, white papers, and so on.
Endress+Hauser needs to take a page from Emerson’s book. This unresponsive site makes it difficult to find the devices, much less the documentation. On the other hand, the new version of the Applicator, where you scale out different devices, looks gorgeous! And guess what? The page is responsive! Well, sort of. The scale out part kind of isn’t, and that’s kind of the important part. Almost there, y’all. You can do it!
If you need a device with seamless integration, then pick the Promass F 200. If you want a simple, pleasant device with wider environment ranges, check out the Micro Motion 2200S. In general, both devices have excellent features and accuracy, but in the end, it always depends on your application and your preferences.
