The Picomag electromagnetic flow meter is a smart and cost-efficient flow meter by Endress+Hauser, designed for water and other applications. The Picomag follows industry trends with excellent features that may put it in front of its competitors, even as a budget meter.

Picomag specifications

The Picomag DMA15/20/25/50 has a simple but outstanding design and practically fits in the pocket. By outstanding, we mean that the device won the Red Dot Design Award in 2018. It has a local display that shows two process variables. It defaults to volume flow and temperature, but we can change it to volume flow and totalizer, temperature and totalizer, or whatever floats in the boat.

Also, the display can show the device tag and status as well as Bluetooth and IO-link communication. Plus we 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 the parameters or switch the Bluetooth on.

Picomag applications

The Picomag measures temperature and volume flow bidirectionally. It can fit many industries and applications and is a solid choice for any conductive product. 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, we 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 repeatability of +-2 o.f.s. It also requires less inlet and outlet run than usual; we only need three times the diameter before the meter and one after.

Picomag verdict

The Picomag IO-Link offers a good range of possibilities to connect to the control system – analog, pulse, switch output, and 2-10 volts. And we can get status input and or the possibility to integrate using IO-Link!

To configure it, we just need to connect with it using the SmartBlue App (up to 10 meters). The app is free, and we 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, IO-Link brings a lot of benefits, such as smooth configuration and automatic reconfiguration.


As a cost-efficient electromagnetic flow meter, the Picomag offers some nifty features and good possibilities. If we have an application that doesn’t need pinpoint accuracy and has a conductive product, then we might save some money trying the Picomag on for size.
