Product Review: OMEGA FMG600 Series magnetic flow meter

You’re absolutely right, I didn’t write many product reviews at the end of last year! I used that time to work on new types of content to find out if they could help our audience better. In that vein, I created our buyer guides, combining existing Visaya content and adding details to update the info. Have you read them? What do you think? Let us know!

And now back to our program. Today in the new season of product reviews, OMEGA brought the FMG600 Series electromagnetic flow meter. As usual, we’ll go in depth on the technical features and find out where you can use this meter. Let’s get started!

Disclaimer: This product review examines only features, not performance. If you’ve used this device, feel free to share your experience in the comments.

Whatcha got there?

Firstly,  we have completely new styling here! The FMG600 has broken from the pack with its housing dimensions and design. While familiarity can help, we shouldn’t stagnate, so it’s good to see vendors trying new approaches.

It has a display for local setup – straightforward, just two lines, illuminated background, and four buttons. And if you take your cue from the device menu, then the setup process looks fairly direct too. Installing and checking data in the field shouldn’t give you any trouble at all. While some transmitters make the display optional, I like having it already there. It saves some hassle, and for people with tight budgets, some money too.

What can it do?

The FMG600 can measure volumetric flow in liquids with an accuracy of +-0.5 percent with minimum installation requirements. Okay, so what are the requirements, you ask? Glad you asked! You have several – pressure, temperature, outlet/inlet run, size of the measuring tube. Did I get them all? Think so.

Oh wait, liquid conductivity, the most important! Your fluid has to have a minimum of 20 micro-siemens (µS), or the meter won’t work right. Usually, magmeters sport a wide range of conductivity requirements, but 5 µS is the most common minimum range. Bit of a shortcoming on the FMG600 here.

Anyway, you have two ways to install this meter in your process, with flanges or sanitary tri-clamps. The installation using flanges can go in pipes from 19 to 305 millimeters (mm), and sanitary tri-clamps will fit 13 to 305 mm.

Sadly, the FMG600 lacks liner options. It only offers Teflon PTFE, limiting its range of applications. Still, the PTFE supports a bunch of different products, so for a low-budget option that should suffice.

On the other hand, you can select two types of electrode material. Hastelloy A4 comes standard, but you can get tantalum optionally. OMEGA says that you can apply the FMG600 in wastewater, slurry, or food applications. Just not all together, because ew.

Why should I care?

Because while it may have limitations, it may still fit your process. Yes, the FMG600 has only four outputs for the control system and a power supply of 24 volts direct or 115/230 volts of alternating current. But you can choose analog, frequency, relay, or RS485 for communications.  Although if you want HART, you’ll have to keep shopping.

And it has potential! One thing caught my attention on the technical manual: it has a USB connection! But you can’t use it. OMEGA put it on there for factory calibration. Come on, OMEGA! Don’t let this beautiful opportunity go to waste! Other meters have begun to offer USB functionality to outshine competitors. OMEGA could easily do the same with the FMG600. Am I right?

Okay, back to the review. This device supports a maximum pressure of 145 pounds per square inch and process temperature from 0 to 50 degrees Celsius for the transmitter integrated with the measuring tube. On a remote device, you get 0 to 150 degrees. It also has IP67, giving you a storage temperature from -10 to 70 degrees Celsius and relative humidity of 70 percent.

Conclusion

The FMG600 will cover many standard flow applications. It could stand a few more liner and output options, or maybe a dab of HART to set up remotely. But if you like the accuracy, then scale it out to see if it’ll fit your process.
