The KROHNE MFC 400 mass flow converter provides the highest possible performance across a wide range of applications. For the measurement of liquids or gases from cryogenic to high temperature fluids, single or multi-phase fluids and advanced digital signal processing techniques give stable and accurate measurements of mass flow, density and temperature.
The MFC 400 systems' Entrained Gas Management (EGM) offers high performance with air entrainment, delivering continuous measurement even with 0 to 100% gas entrainment. For standard applications, the compact housing is mounted directly on the flow sensor. In the unlikely event of a failure, the electronics can be easily exchanged and reconfigured using a backup data set stored in the housing. The signal converter in the robust field housing is generally used when it is difficult to access the measuring point or when ambient conditions do not allow the use of the compact version.
The basic signal converter variant covers a current output including HART, pulse/frequency output, status output, control input and a current input. The modular input/output variant allows for any combination of up to four inputs and outputs. All inputs and outputs are galvanically isolated from each other and from the rest of the electronic equipment. Inputs and outputs can be passive or active. In addition, the electronics can be equipped with fieldbus functionality including HART, RS485 Modbus, FOUNDATION Fieldbus, PROFIBUS PA/DP and PROFINET IO to enable communication of measuring values and diagnostic information to any third party system. Device commissioning, verification, diagnostics and monitoring can be transmitted via secure wireless Bluetooth connection using the free download OPTICHECK Flow Mobile app for Google Android and Apple iOS smartphone and tablet.
The MFC 400 has been developed according to IEC 61508, and depending on the I/O and flow sensor variant, it is suited for use in safety applications SIL 2/3. Conforming to the NAMUR standard NE 107 for status and error handling, the MFC 400 features enhanced meter diagnostics that provide extensive self-checking of internal circuits, information regarding the health of the flow sensor, and vital information about the process and process conditions.
