KROHNE OPTIMASS 6400 vs. TRICOR TCE 8000
Hey hey! Today we have two new fighters, one of them a relevant vendor in the flow meter market and the other a quiet new competitor you’ve probably never heard of.
We do these comparisons to give you more information for you to draw your own conclusions before you buy. Keep in mind that you need to scale out these meters. If you pick only by features, then you may wind up with a big surprise. Of course performance counts most, but certain features can sway your decision if you have meters with the same performance. You need to choose which will benefit your process the most.
All right, let’s get it on! On the right we have the TCE 8000 from TRICOR, and on the left, a big crowd favorite, the OPTIMASS 6400 from KROHNE!
Just take a seat, grab a beer, have a read, and draw your conclusions!
Full disclosure: This comparison covers only the features of the device, not the performance. If any community members have installed and used these devices, please comment below with your experiences so we all can learn more. Thanks!
KROHNE set up the OPTIMASS 6400 with a standard design, but the transmitter makes a good first impression. Navigating the configuration feels comfortable, and the LCD display offers fine visualization of your process values.
The 6400 provides simple installation, commissioning, and operation in a friendly way, like KROHNE designed it to make you feel good about using it. The touchscreen display looks a lot like other devices out there, but that just makes it easy to use too.
The 8000 seems simple, too. But behind the plain facade you have enough features for daily flow measurement. Unfortunately, if you want to set up the meter through the display, you have to open the housing to access the buttons. No touchscreen here. On the positive side, sometimes the touchscreen makes set up harder, especially with gloves. So the 8000 gains a little ground there.
Sad to say, I set my expectations for KROHNE too high. The OPTIMASS 6400 offers HART, FOUNDATION Fieldbus, PROFIBUS DP/PA, and Modbus. However, I expected EtherNet-IP, PROFINET, or wirelessHART built in.
Too bad for me – and KROHNE if you expected those too.
Still, you’ll get the traditional analog, pulse, status, and limit switch. Seamless communication guaranteed with most control systems on the market, right? Probably.
The 8000 gave me a surprise, because this simple device covers HART, FOUNDATION Fieldbus, and Modbus RTU! Plus they have a note on the technical document that says, “other options on request.” Ooh, ooh, could you do an ISA100 flow meter, please?
The transmitter also has analog, status, and pulse! Those options give you a ton of possibilities. But it could have better integration, and TRICOR should make the device description (DD) files available on its website to download. C’mon, TRICOR. We can host you. 🙂
The 6400 has three types of wetted sensor, stainless steel, Hastelloy, or duplex stainless steel. These three materials will cover most applications, but you’ll still need to scale out and check chemical compatibility with your process product.
You can implement the OPTIMASS 6400 in a nominal flow rate to 1000000 kilograms per hour, assuming the specific conditions mentioned in the technical manual. The flow meter also provides plenty of process connections like DIN, ASME, JIS, and more. KROHNE has a whole lineup of devices, each offering different features, materials and benefits for your application, like the 1400, 2400, 7400, and others.
You have a similar story with the 8000. TRICOR could make our lives easier by combining these models. But never mind that. You mainly need to know that the 8000 goes up to 230000 kilograms per hour. It only has stainless steel for material, 1.4404/AISI 316L tube and housing material. However, it also provides good process connections like ANSI, weld neck, Tri-clamp, and others.
Remember, for this one the vendor operates in ideal conditions. You don’t, so scale out! The standard option of the 6400 offers a liquid mass flow accuracy of +-0.1 percent of actual measured flow rate and +-0.35 percent in a gas application. The special option gives your liquid mass flow an accuracy of 0.05 percent of actual measured flow rate. Nice, huh?
Now, for density, the standard accuracy is +-1 kilogram per cubic meter. If you do an onsite calibration, then you can increase the accuracy to +-0.2. I had a chance to do a field density calibration in my carrier, and the procedure is simple, so consider this option!
Our colleagues from TRICOR offer good accuracy too. Liquid is +-0.1 percent and density 1 kilogram per cubic meter. In gas, you’ll get +-0.25 percent with a density of +-2.0.
If you want a special calibration, then TRICOR can do it for you!
Information and documentation
You know my opinion on info and docs. All vendors should have good websites or at least microsites with all data related to the flow meter available to download.
KROHNE has a weak site – traditional, barely responsive on mobile, and issues finding what you want. On the other hand, they have a microsite for the 6400 which seems pretty responsive, with easy to find info and a good user experience. That’ll do.
The documentation in general is good, with tables and videos. However, if you need a download, then you have to go back to the clunky main website. Gives with one hand, takes with the other.
TRICOR does a better job with a simple, clean, and responsive website where you can easily find most of the information you need. On the negative side, the documents take some serious staring to figure out, and the site doesn’t have basic downloads like DD files. Come on, guys!
The 6400 has some good gimmicks. I liked the auto test of the flow meter as soon as you install it. The test covers 90 percent of the meter and gives you data on the configuration, status, and other points.
I just wish KROHNE had more info on this feature.
Also, if your process has entrained gas conditions, then the OPTIMASS 6400 ensures continuous measurement. Of course, its competitors can do the same, and most of them have videos to show this feature in action.
Last but not least, it has redundant data storage. If you have a problem with the electronics, then you can switch the old for new and won’t need to set up the meter again!
I already told you the 8000 is pretty basic, but it does have one surprisingly good feature. If you want to check the proportion of oil and water in your product, the Net Oil software will do that. Pretty nifty for a basic device, huh?
Obviously either device could suit your process, once you’ve scaled them out and checked them against your process requirements.
The OPTIMASS 6400 has more features, process materials and other things, making it a fancier flow meter than the 8000. But if you just need something that’ll do the job and not break the bank, then the 8000 may suit you better.
