MFC 300PRODUCT FEATURES 11.1 The signal converter with the highest performanceThe MFC 300 is a universal Coriolis mass flow signal converter suitable for a wide range ofapplications and installations. The common platform for the modular hardware allows easyselection for the required output options, and is suitable for mounting in various housingconfigurations.The MFC 300 is also suitable for all current and future mass flow sensors. The split architecturesolution for the mass flow family ensures maximum security and redundant back-up ofcalibration parameters, should a failure occur. There is no need for reprogramming after afailed unit is replaced.(signal converter in compact housing)1 Communication with any third party system possible via Foundation Fieldbus, Profibus PA/DP or Modbus2 Intuitive navigation and a wide variety of languages integrated as standard for ease of operation3 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 housing2 Any combination of up to 4 inputs and outputs is possible11/2009 - 4000498402 - TD MFC 300 R03 enwww.krohne.com3

MFC 300PRODUCT FEATURES 11.2 Options and variantsModular converter concept(signal converter in compact housing)The MFC 300 mass flow signal converter is availablein different variants and offers superiorperformance in any conceivable application.From process control in chemistry, to density andconcentration measurements in the food andbeverage industry, to custody transfer filling andtransport measurements for oil and gas right downto conveyor systems in the pulp and paper industry.Coriolis mass flow measuring systems measure themass and volume flow, the density and thetemperature of liquids and gases. In addition, theconcentration in mixtures and slurries can also bedetermined.Remote design in various versionsThe signal converter in the wall-mounted housing isgenerally used when it is difficult to access themeasuring point or when ambient conditions do notallow the use of the compact version.(signal converter in wall-mounted housing)The signal converter in the 19" rack-mountedhousing is typically built into the central controlroom, away from the harsh ambient conditions thatcan be present at the measuring point.(signal converter in 19" rack-mounted housing)11/2009 - 4000498402 - TD MFC 300 R03 enwww.krohne.com5

1 PRODUCT FEATURESMFC 300Signal converter for any applicationThe basic variant covers many applications,featuring a current output with HART ® ,pulse/frequency output, status output and controlinput.In the modular input/output variant, up to four inputsand outputs can be combined in almost any way. Youcan also select passive or active inputs/outputs.All inputs and outputs are galvanically isolated fromeach other and from the rest of the electronicequipment.(signal converter in field housing)Dual-phase pulse outputs are available for custodytransfer measurements.In addition, the electronics can be equipped withFieldbus functionality (i.e. Foundation Fieldbus,Profibus PA/DP, Modbus, etc.) enablingcommunication to any third party system.For devices without Fieldbus functionality, HART ® isstandard on the first current output.DiagnosticsThe default functionality includes extensive selfdiagnosisof the device, its installation and itsapplication. This is done without any additionalsensors, providing you with valuable informationabout the current status of the device, itsmeasurement and its application. One example isthe 2-phase flow signal which can displayinterferences caused by outgassing.For difficult applications, a toolbox is offered. Thatallows you to record all measuring and diagnosticvalues online over a longer period of time and thenevaluate them using toolbox software.As a result, we offer you peace of mind and reductionof operational and maintenance costs.6www.krohne.com11/2009 - 4000498402 - TD MFC 300 R03 en

1 PRODUCT FEATURESMFC 300Energised meter1 Measuring tubes2 Direction of oscilation3 Sine waveWhen the meter is energised, the drive coil vibrates the measuring tube causing it to oscillateand produce a sine wave 3. The sine wave is monitored by the two sensors.Energised meter with process flow1 Process flow2 Sine wave3 Phase shiftWhen a fluid or gas passes through the tube, the coriolis effect causes a phase shift in the sinewave that is detected by the two sensors. This phase shift is directly proportional to the massflow.Density measurement is made by evaluation of the frequency of vibration and temperaturemeasurement is made using a Pt500 sensor.8www.krohne.com11/2009 - 4000498402 - TD MFC 300 R03 en

3 INSTALLATIONMFC 3003.1 Intended useThe mass flowmeters are designed exclusively to directly measure mass flow rates, productdensity and temperature as well to indirectly measure parameters such as the total volume andconcentration of dissolved substances as well as the volume flow rate.For devices used in hazardous areas, additional safety notes apply; please refer to the Exdocumentation.3.2 Installation specificationsThe following precautions must be taken to ensure reliable installation.• Make sure that there is adequate space to the sides.• Protect the signal converter from direct sunlight and install a sun shade if necessary.• Signal converters installed in control cabinets require adequate cooling, e.g. by fan or heatexchanger.• Do not expose the signal converter to intense vibration. The flowmeters are tested for avibration level in accordance with IEC 68-2-3.3.3 Mounting of the compact versionThe signal converter is mounted directly on the measuring sensor. For installation of theflowmeter, please observe the instructions in the supplied product documentation for themeasuring sensor.3.4 Mounting the field housing, remote versionAssembly materials and tools are not part of the delivery.
