All processes at a single glance at any time

The high-performance MFX_4 flow computer complies with the highest standards, allowing for flexible and reliable custody transfer measurement and blending as well as the management of processes for the handling of liquids and, in particular oil. With more than 30 years of operating experience and in excess of 18,000 installations the fourth generation combines long-standing industry know-how with state-of-the-art technologies.

Thanks to its support of various protocols and communication standards all MFX_4 systems are easy to integrate, can be configured quickly and can be serviced remotely during ongoing operations. The MFX-4 flow computer sets itself apart with its distributed architecture made up of centralised processing units and decentralised operating units, thus substantially expanding the range of possible applications.

An exceptional system in detail

MFX_4 Controller

The MFX_4 Controller is the centralised control unit of the MFX_4 system. It is available in two housing variants as an explosion-proof (Ex) as well as an unprotected device, whereby the functionality of the electronics is identical. Depending on the model, it can be used both in the control room and under extreme weather conditions in explosive external areas.

configurable for individual applications for blending or additivation and including an integrated PLC control system via scripting

MFX_4 Terminal Pro

The MFX_4 Terminal Pro widens our range of HMI devices based on our proven MFX_4 Terminal. It offers an impressive user friendly interface with a high contrast 10,4” colour display enabling the reading from larger distances. Just like the MFX_4 Terminal, it is a multi-language Human Machine Interface (HMI) to interact with MFX_4 Controller, other suitable terminals or with host computer systems via a wide range of communication protocols.

user friendly, easy-to-understand and easy-to-read communication unit (e.g. for measurement data processors such as the MFX_4 Controller)

MFX_4 Terminal

The MFX_4 Terminal is the human-machine interface (HMI) via which communication with the Controller, other suitable terminals or a SCADA system takes place. To ensure optimum operability, it is equipped with a configurable graphic display and is able to display all process data in various sizes and languages.

MFX_4 Compact

The MFX_4 Compact combines all functionalities of the MFX_4 Controller and MFX_4 Terminal in a single explosion-proof (Ex) housing. Thanks to its compact size, the MFX_4 Compact is also suitable for use in small systems.

especially suitable for smaller systems in which a single housing is advantageous

MFX_4 RFID Reader

The MFX_4 RFID Reader allows the touchless identification in hazardous areas under potentially explosive atmospheres. The multi-format 13,56 MHz reader is certified to be used in Zone 1 according to ATEX and IECEx and thus almost for nearly all Ex-environments. In addition to be used with the MFX_4 Terminal Pro and the MFX_4 Terminal, it offers the individual operation as a stand-alone reader with visual feedback.
