Comparison: Schneider 244LVP vs Magnetrol E3 Modulevel

Today, Visaya has two big companies in for product reviews! In the multi-colored corner, Magnetrol has returned, bringing the Digital E3 Modulevel! In the bright green, the folks from Schneider have the 244LVP up for grabs! Let’s learn more about these devices and how they might fit into your application.

Unboxing

Big boxes today! Displacer level transmitters are kinda chunky, but that’s a trivial detail.

The E3 Modulevel has the same housing as other level devices from Magnetrol, which means anyone who has bought from Magnetrol before already knows its interface. This housing has two parts, one to access the power connection and the other for the display and electronic module.  If you choose the remote version, you get a third part to connect the transmitter to the sensor. It comes in aluminum A356-7 (less than 0.20 percent copper), but you can request it in 316 stainless steel.

The E3 Modulevel has a local setup with three push buttons, up, down, and enter. So you can configure the device using its LCD, simple but enough for this activity. In fact, the whole setup looks simple; you can handle it quickly without the manual and even use a handheld to speed up the process.

The 244LVP has a lovely old style! It looks dated but durable. It also has two parts, one for power and communication, the other for the display and electronic module. The local display won’t give you anything fancy, just the device menu, current output, percent, and process variable. The local setup uses two buttons on the side rather than the front. That and the complex procedure bring down the user experience.

The 244LVP comes with infrared (IR) communication, which is nice but slow and outdated compared to Bluetooth. Better than those buttons, though. You can get the housing in aluminum, polyurethane coated, or 316L stainless steel.

Measurement and probe

As displacers, both devices can measure level, interface, and density of liquids. As I mentioned earlier, this technology is old but still useful in a range of applications.

The Schneider device has a standard accuracy of +-0.2 percent, although a special adjustment can improve its accuracy. You can use it in temps from -50 to 120 degrees Celsius and pressures up to 40 bar.

Somehow, I found two different measurement ranges. The first says 0 to 50 millimeters. Okay. But the second says 50 mm to 15 meters! Drop me a comment if you know which one’s right!

Anyway, you can get wetted parts in stainless steel 1.4404 or 1.4572. The displacer itself has several choices like PTFE, stainless steel, and Hastelloy C. You can install the device using process flanges of various sizes, and you can also use the 204DC displacer chamber with extra accessories.

The Magnetrol device measures a range from 356 to 3948 millimeters. I didn’t find the standard accuracy for it, so you’ll need to scale it out for your process to find out more.

It can handle temps from -29 to 454 degrees Celsius and pressures up to 355 bar at 38 degrees Celsius. Its chamber material comes in carbon steel or 316/316L stainless steel, the wetted parts in 316/316L stainless steel, and the spring in Inconel.

Like the Schneider device, the E3 Modulevel connects with a ANSI flange in various sizes, such as three, four, and six inches. Beyond the flange connection, you can fit the device with a chamber installation. Then you have process connections like socket welds, ANSI flanges, and more.

Field protocols and output

These devices don’t offer much in the way of fancy communication. The E3 Modulevel integrates with analog, HART, and FOUNDATION Fieldbus (FF). These cover the basics for standard displacer industries, like petrochemical or oil and gas. However, it lacks PROFIBUS or an integrated wireless solution. Who wants to pioneer wireless on displacers?

The 244LVP has similar offerings and shortcomings. But if you want  PROFIBUS, then Schneider has another model that has it as a native option. Also, both devices can do HART over PROFIBUS, if you want to try that. If not, then you’ll have to take a pass on these.

Approvals

The E3 Modulevel comes with explosion-proof, intrinsically safe, and non-incendiary certification from FM, CSA, ATEX, and IEC. It also has Type 4x and IP66 ratings and SIL 2 certification with a safety failure fraction (SFF) of 92.3 percent. Not bad at all!

The 244LVP is also intrinsically safe and explosion-proof, with an IP66 rating and a SIL 2 certification with an SFF of 91 percent.

Fancy features

Not today! Next topic!

Information and documentation

The Magnetrol website makes your experience on a smartphone or tablet rather underwhelming. The site looks old, but finding information is easy, because it has a short list of products. Could be worse! On the upside, the application area, where you can select part of a process and see recommended devices, is very cool! The documentation could use some organizing and updating, though.

The Schneider website brings a good user experience on smartphones and tablet, but finding what you want is complicated. You’re better off using Google than the site’s search engine. In the plus column, the documentation looks good, so you’ll find your answers once you find your document.

Conclusion

Both devices present near-identical features, mostly varying in types of material and measurement ranges. If they sound good to you, then scale them out. Also, find out which company offers better local support for you. You may need that help down the line.
