MFC 300

PRODUCT FEATURES 1

1.1 The signal converter with the highest performance

The MFC 300

MFC 300 is a universal Coriolis mass flow signal converter suitable for a wide range of

MFC 300MFC 300
applications and installations. The common platform for the modular hardware allows easy
selection for the required output options, and is suitable for mounting in various housing
configurations.

The MFC 300

MFC 300 is also suitable for all current and future mass flow sensors. The split architecture

MFC 300MFC 300
solution for the mass flow family ensures maximum security and redundant back-up of
calibration parameters, should a failure occur. There is no need for reprogramming after a
failed unit is replaced.

(signal converter in compact housing)

1 Communication with any third party system possible via Foundation Fieldbus, Profibus PA/DP or Modbus
2 Intuitive navigation and a wide variety of languages integrated as standard for ease of operation
3 Supply voltage: 100...230 VAC (standard) and 24 VDC or 24 VAC/DC (optional)

(signal converter in wall-mounted housing)

1 Large backlit graphic display with 4 optical buttons to operate the signal converter without having to open the housing
2 Any combination of up to 4 inputs and outputs is possible

1.2 Options and variants

Modular converter concept

(signal converter in compact housing)

PRODUCT FEATURES 1

The MFC 300 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.

Remote design in various versions

(signal converter in wall-mounted housing)

The signal converter in the wall-mounted 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 signal converter in the 19" rack-mounted
housing is typically built into the central control
room, away from the harsh ambient conditions that
can be present at the measuring point.

1 PRODUCT FEATURES

Signal converter for any application

(signal converter in field housing)

MFC 300

The basic variant covers many applications,
featuring a current output with HART

®

,
pulse/frequency output, status output and control
input.

In the modular input/output variant, up to four inputs
and outputs can be combined in almost any way. You
can also select passive or active inputs/outputs.
All inputs and outputs are galvanically isolated from
each other and from the rest of the electronic
equipment.

Dual-phase pulse outputs are available for custody
transfer measurements.

In addition, the electronics can be equipped with
Fieldbus functionality (i.e. Foundation Fieldbus,
Profibus PA/DP, Modbus, etc.) enabling
communication to any third party system.

®

For devices without Fieldbus functionality, HART

is

standard on the first current output.

Diagnostics

The default functionality includes extensive self­diagnosis of the device, its installation and its
application. This is done without any additional
sensors, providing you with valuable information
about the current status of the device, its
measurement and its application. One example is
the 2-phase flow signal which can display
interferences caused by outgassing.

For difficult applications, a toolbox is offered. That
allows you to record all measuring and diagnostic
values online over a longer period of time and then
evaluate them using toolbox software.

As a result, we offer you peace of mind and reduction
of operational and maintenance costs.

1.4 Measuring principle (single tube)

Static meter not energised and with no flow

1 Measuring tube
2 Drive coil
3 Sensor 1
4 Sensor 2

A Coriolis single tube mass flowmeter consists of a single measuring tube 1 a drive coil 2 and
two sensors (3 and 4) that are positioned either side of the drive coil.

1 PRODUCT FEATURES

Energised meter

1 Measuring tubes
2 Direction of oscilation
3 Sine wave

When the meter is energised, the drive coil vibrates the measuring tube causing it to oscillate
and produce a sine wave 3. The sine wave is monitored by the two sensors.

MFC 300

Energised meter with process flow

1 Process flow
2 Sine wave
3 Phase shift

When a fluid or gas passes through the tube, the coriolis effect causes a phase shift in the sine
wave that is detected by the two sensors. This phase shift is directly proportional to the mass
flow.

Density measurement is made by evaluation of the frequency of vibration and temperature
measurement is made using a Pt500 sensor.
