PRODUCT FEATURES

1.1 The high performance signal converter for all applications

The MFC 400

MFC 400 Coriolis mass flow signal converter will provide the highest performance possible

MFC 400MFC 400 across a wide range of applications. For the measurement of liquids or gases, cryogenic to high temperature fluids, single or multi-phase fluids and advanced digital signal processing techniques is used to give stable and accurate measurements of mass flow, density and temperature.

It is developed according to IEC 61508 and depending on the I/O and flow sensor variant 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. This provides extensive self-checking of internal circuits and information regarding the health of the flow sensor, but just as importantly, vital information about the process and process conditions.

Measuring values and diagnostic information can be transmitted via field bus interfaces including HART

, RS485 Modbus, FOUNDATION™ Fieldbus, PROFIBUS

and PROFINET IO.

EGMEGM

Entrained Gas Management Entrained Gas Management

EGM™ was developed for the OPTIMASS Coriolis mass flowmeters to overcome problems caused by air or gas entrainments in a liquid. Powerful control algorithms maintain measurement, even during a complete transition from a pure liquid phase to a gas phase and back. Mass flow and density measurements remain stable and continuous, which has been demonstrated in batch / loading / empty-full-empty applications.

1.2 Options and variants

Compact design for standard applications

(Example: OPTIMASS 6400 – compact)

PRODUCT FEATURES

The MFC 400 mass flow signal converter is available in different variants and offers superior performance in any conceivable application. From process control in chemistry, to density and concentration measurements in the food and beverage industry, to custody transfer filling and transport measurements for oil and gas right down to conveyor systems in the pulp and paper industry.

Coriolis mass flow measuring systems measure the mass and volume flow, the density and the temperature of liquids and gases. In addition, the concentration in mixtures and slurries can also be determined.

Thanks to Entrained Gas Management (EGM MFC 400 systems offer high performance with air entrainment, delivering continuous measurement even with 0...100% gas entrainment.

) the

(Example: OPTIMASS 2400 – compact)

Remote field housing version

For standard applications the compact housing is mounted directly on the measuring sensor. In the unlikely event of a failure, the electronics can be easily exchanged and reconfigured using a backup data set that is 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.
