Electromagnetic flowmeters – Overview & Highlights

Human Machine Interface (HMI): Simply clever, simply well thought-out

Human Machine Interface (HMI): Simply clever, simply well thought-out

User-friendliness begins with selecting the right display and control elements. But it certainly does not end there. With the market launch of the OPTIFLUX series in 2004, KROHNE has proven in an impressive way how to significantly improve user-friendliness by using pioneering assistance and diagnostics systems.

It all starts with the display: All devices feature a large, high-contrast display which makes it possible to display plain text information as well as graphic information such as the trend development of the flow. Operation is simple and convenient thanks to a user-friendly interface with four optical buttons. Not only does it look good – it’s also extremely practical. For example, the glass cover which protects the display from dirt and dust does not have to be removed during parameterization or operation.

Using the Quick Setup menus, the user can quickly adapt the OPTIFLUX to the application. The converter can communicate with the user in many languages including German, English, French and Spanish.

Modular product lines: Many combinations for one customised solution

At KROHNE, we believe in the concept of modularity when it comes to offering our customers the measuring solution best suited to their process. Both our IFC and MFC converters can be freely combined with all devices in the OPTIFLUX and OPTIMASS lines. This modularity is also reflected in the names of the devices. For example, the OPTIFLUX 1300 is a combination of the OPTIFLUX 1000 sensor and the IFC 300 converter.
