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.

Entrained Gas Management

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.

Communication options

1 Monitoring system 2 Gateway 3 Flowmeter

MFC 400

The basic signal converter variant covers a current

output including HART 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 Foundation Fieldbus, Profibus PA/DP, Modbus or PROFINET IO to enable communication to any third party system.

New: PROFINET IO option

(1. point-to-point or star communication)

With PROFINET IO, real time Ethernet can be connected to IoT scenarios.

The use of existing, legacy, industry-grade devices (e.g. PROFINET flow sensors, actuators and

Programmable Logic Controllers (PLC’s)) enables a

new architecture to be used across the Internet.

An unique network topology:

1. Working with point-to-point or star communication using a single Ethernet port and an external switch.

2. Using ring or line communication there are two Ethernet ports available controlled by an internal switch.

Extensive diagnostics of the device and application

PRODUCT FEATURES

The primary focus of a user for a flowmeter is that it delivers reliable and robust measurements. To achieve this all Coriolis mass flowmeters are calibrated before leaving the factory.

In addition, KROHNE was one of the first to introduce extensive diagnostic features.

The MFC 400 provides a wide range diagnostic functions on the flow sensor, signal converter and process integrated in the signal converter.

OPTICHECK tool for on-site verification

(Suitcase with OPTICHECK and all cables and

accessories)

Potential problems that may occur in the process including gas bubbles, solids, corrosion, deposits, empty pipe and partial filling of the flow sensor.

Diagnostic info available via local display, status outputs, Fieldbuses, PACTware, xFC toolbox or the OPTICHECK.

The OPTICHECK provides an inline health check of the device under test by an external tool.

A hard copy of the verification report can be printed for every flowmeter. The verification data are digitally stored.
