Micro Motion 2200S
After an entire month of liquid analysis, specifically pH measurement, it’s time to discuss another topic! We already reviewed a couple of Coriolis meters here, but we still have a long way to go to review all the flow meters on the market. Yep, that’s our goal! Stay tuned to see when we achieve it!
So when I say “Coriolis flow meter,” one of the companies that should come your mind is Emerson with its Micro Motion. Did you know Emerson created the first Coriolis flow meter? We’ll talk about that in another article, so keep an eye out for it!
Today we’ll discuss two-wire flow meters. This setup can save you money in installation and service over the four-wire type. Therefore, you should determine whether your application can support a two-wire device. And vendors have a surprising number of options now, so if this one doesn’t work for you, take a look at the market for more.
But let’s see if this one will work for you first! Say hi to the Micro Motion 2200S! We’ll check out the features this device has and how they can support your process.

Whatcha got there?
The Micro Motion 2200S has a compact design and simple interface. You can set up the transmitter locally using the buttons on the front display. However, you have to remove the housing cover to do the configuration. Frankly, I don’t understand why it doesn’t work the same way as the 2400S, where you don’t have to open the cover, but okay.
The simple LCD display shows one process variable, the unit of measure, and an optional alarm indicator. The menu navigation is fairly easy, but only having scroll and enter functions means it’ll take you a while to set up, not to mention time to learn how to use the buttons.
On the downside, the 2200s lacks a remote option; it integrates directly into the sensor. You can get a remote HART or analog display to show the process data, but that’ll cost more. On the up side, the housing comes in polyurethane-painted cast aluminum or 316 stainless steel, to give you more options.
As for seamless integration, this meter falls short of market standards. You have analog and HART, and the reps highlight the wirelessHART protocol. No FOUNDATION Fieldbus or PROFIBUS PA, though. This limitation severely cuts into the range of applications you can tuck this device into. Of course, if you have analog or HART, then you’re set!
What can it do?
Coriolis meters offer the most flexibility and accuracy on the market, along with a bunch of data from your process. The Micro Motion 2200S dittoes all that, with its dual sensors and a long list of information spilling out of it.
It starts with the basics – mass flow, temperature, and density. Then, based on the other information, you can get the volume flow as well, although these measurements depend on the type of sensor you pick. The Micro Motion line has a grand list of sensors for various applications and segments.
You can scale it out with ELITE sensors, for the best performance of the portfolio, or with the F-Series or H-series sensors, if you don’t need the top of the line. Check out the chart I found on the Micro Motion website to match sensor to the transmitter.
The 2200S can use sensors between an eighth of an inch up to six inches for ELITE and a quarter of an inch to four inches for F-Series. If you get an ELITE, then you’ll get an accuracy of mass and volume flow of +-0.1 percent of rate in liquid and +-0.30 percent of rate in gas. An F-Series will give you an accuracy of +-0.2 percent in liquid and +-0.50 percent in gas.
We’ll stick with the ELITE for this review, but keep in mind you can pick the F-Series or H-Series if you like. Oh, just so you know, the “H” on the H-Series stands for “hygienic,” a relevant tip for y’all working the food and beverage industry. Anyway, the ELITE can withstand process temperatures from -240 to 204 degrees Celsius, and pressures from 100 to 413 bar. That will cover quite a few applications, I think!
Why should I care?
Although the Micro Motion 2200S uses loop power, it’s a little different from the others. It has a standard output of 12-20 milliamps (mA) instead of 4-20. If you connect the cable from the control system directly to the device, you’ll get 12-20 mA. However, if you add an adapter-barrier from Micro Motion between the control system and the device, then you get 4-20 mA from the barrier to the control, but 12-20mA from the device to the barrier.
What’s the problem here? Well, because it’s not a real 4-20 mA, you may have resolution issues. Developers created this “technical” solution to get the device to work if you don’t have 12 mA, and technically, it isn’t wrong. But Emerson’s competitors have solved this problem in more efficient ways. Just a thought.
On the plus side, the 2200S offers tons of approvals for using it in hazardous and harsh environments. You can also run advanced diagnostics and check performance through the PROLINK or a field communicator.
It’s hard to go awry with Emerson and its Micro Motion line, especially with an ELITE sensor or two. The 2200S has a few drawbacks that may make you want to consider other options in the portfolio or on the market, but you won’t know until you drop your specs in and scale it out. Tired of seeing that line yet? Hope not, because you’ll see it again!
