The CoriolisMaster FCD450 is ABB's dedicated low-flow Coriolis mass flowmeter for accurate measurement of liquids, gases and steam.
The meter is available in DN8 (5/16 in.) and DN10 (3/8 in.) sizes, with maximum measuring ranges of 600 kg/h and 2,500 kg/h respectively. ABB specifies a compact design that does not require conventional upstream or downstream piping sections, allowing the FCD450 to be installed in tight spaces.
The FCD450 is also equipped with ABB's SmartSensor technology, SensorApplicationMemory and VeriMass onboard verification and diagnostics. Depending on configuration, Ethernet and Ethernet-APL connectivity provide remote access to diagnostics, configuration and flowmeter verification through the built-in webserver.

Suitable Applications
Low-Flow Process Measurement
The FCD450 is designed for applications where process flow rates are too low for many conventional industrial flowmeters.
Dosing and Filling
The compact meter is suitable for precise dosing and filling systems. Its FillMass software provides dedicated filling application control.
Concentration Measurement
The optional DensiMass software enables direct concentration measurement based on the Coriolis measurement capabilities.
Gas and Steam Measurement
ABB specifically positions the FCD450 for low flow rates of liquids, gases and steam, making it suitable for specialized process and equipment applications.
Compact Skids and Equipment
The small meter sizes and lack of conventional straight-pipe requirements make the FCD450 useful for packaged systems, laboratory-scale process equipment and installations with limited space.
Challenging Fluids
The optional Enhanced Coriolis Control (ECC) function is designed for advanced measurement under multiphase and other challenging fluid conditions. The suitability of ECC should be confirmed for the specific application.
Communication
Depending on the selected configuration, the FCD450 supports:
• HART
• PROFIBUS DP / PA
• Modbus RTU
• Standard Ethernet
• Profinet
• Modbus TCP
• Ethernet/IP
• Ethernet-APL with Profinet, Modbus TCP and webserver
The device can also use Power over Ethernet in applicable configurations.
Selection Notes
1. Confirm the actual flow range first.
The FCD450 is specifically designed for low-flow measurement. DN8 covers up to 600 kg/h, while DN10 covers up to 2,500 kg/h. The correct size should be selected according to the actual operating flow range rather than pipe diameter alone.
2. Confirm the process medium.
The FCD450 can measure liquids, gases and steam, but the exact performance and configuration should be checked against the actual medium and operating conditions.
3. Consider DensiMass when concentration measurement is required.
FCD450 with DensiMass can provide direct concentration measurement. The appropriate software and calibration requirements should be confirmed according to the measured medium.
4. Consider FillMass for filling applications.
For automated filling processes, FillMass provides dedicated filling application control and can be considered when the flowmeter is being integrated into a filling system.
5. Confirm the temperature range.
ABB specifies a measuring medium temperature range of -50 to 220 °C for FCD450. Actual limits can depend on the selected configuration and process conditions.
6. Confirm wetted materials.
Available wetted materials include 316L stainless steel and Hastelloy C. Material selection should be checked against the actual process medium and corrosion conditions.
7. Confirm hazardous-area and communication requirements.
ATEX, cFMus and NEPSI approvals are available for applicable configurations. The exact certification and communication interface should be confirmed before quotation.
