Product Review: Picomag electromagnetic flow meter
Good things are continually popping up on the market! Today, we have the Picomag electromagnetic flow meter, a smart and economic magmeter launched recently by Endress+Hauser for many applications. The Picomag follows industry trends with excellent features that may put it in front of its competitors, even as a budget meter. As usual, let’s dig in and see how it can help you in a new flow application. Stick with me, and we’ll suss out the pros and cons of this new device!

Whatcha got there?
The Picomag has a simple but outstanding design and practically fits in your pocket. And by outstanding, I mean the device won the Red Dot Design Award in 2018. Well done, Pico-people! It has a local display that shows two process variables. It defaults to volume flow and temperature, but you can change it to volume flow and totalizer, temperature and totalizer, or whatever floats your boat.
Also, the display can show the device tag and status as well as Bluetooth and IO-link communication. Plus you can get diagnostics such as alarms, function checks, and warning messages. Best of all is the knock function. Yes, just knock on the device, and it’ll pop up your parameters or switch the Bluetooth on. So cool!
What can it do?
The Picomag measures temperature and volume flow bidirectionally. It can fit many industries and applications; if you have conductive product, then you have the Picomag as an option. It has a nominal diameter from half an inch to two inches and measures up to 750 liters per minute. It can also handle pressures up to 16 bar and temps from -10 to 60 degrees Celsius. As for chemical compatibility, you should know that this device comes in PEEK, stainless steel, and FKM for wetted materials and stainless steel for the electrodes. The performance shines as well, with a repeatability of +-2 o.f.s. It also requires less inlet and outlet run than usual; you only need three times the diameter before the meter and one after.
Why should I care?
The Picomag offers a good range of possibilities to connect to your control system – analog, pulse, switch output, and 2-10 volts. And you can get status input and or the possibility to integrate using IO-Link!
To configure it, you just need to connect with it using the SmartBlue App (up to 10 meters). The app is free, and you can download it to iOS or Android. It also has IP 65 and IP67 ratings, and drinking water approvals are pending, according to the website. Last but not least, the IO-Link brings a lot of benefits, such as smooth configuration and automatic reconfiguration.
As an economical electromagnetic flow meter, the Picomag offers some nifty features and good possibilities. If you have an application that doesn’t need pinpoint accuracy and has a conductive product, then you might save some money trying the Picomag on for size. On the right, you can see some other options, so check them out too before you decide.
