The ABB CoriolisMaster FCH400 is the hygienic version of ABB's compact FCB400 Coriolis flowmeter platform. It is designed for processes where cleanability, hygienic construction and reliable multivariable measurement are important.
The series consists of the FCH430 and FCH450 models. Both use Coriolis measurement technology to directly measure mass flow while providing additional process variables such as volume flow, density and temperature.
For hygienic installations, the FCH400 uses 316L wetted materials, EHEDG-certified design and FDA material compliance. The self-draining construction helps minimize retained process liquid during cleaning and drainage operations.
The compact construction also allows installation in tight spaces without conventional upstream and downstream straight-pipe requirements. This can simplify integration into existing hygienic process equipment where installation space is limited.

Model Options
FCH430
The FCH430 is the standard accuracy model within the FCH400 series.
For liquid measurement, ABB specifies:
• Mass and volume accuracy options of 0.4%, 0.25% or 0.2% of reading
• Density accuracy of 10 g/l
• Medium temperature from -50 to 160 °C
• Measuring sizes DN25, DN50 and DN80
FCH450
The FCH450 provides higher available measurement accuracy and additional software functionality.
For liquid measurement, ABB specifies:
• Mass accuracy options of 0.15% or 0.1% of reading
• Volume accuracy of 0.15% of reading
• Density accuracy of 2 or 1 g/l
• Medium temperature from -50 to 205 °C
• DensiMass software for direct concentration measurement
• FillMass software for filling application control
Measuring Range
The available nominal sizes and maximum measuring capacities are:
• DN25 (1 in.): up to 35,000 kg/h
• DN50 (2 in.): up to 90,000 kg/h
• DN80 (3 in.): up to 250,000 kg/h
These are maximum capacities associated with the respective meter sizes. The actual usable measuring range depends on the selected model, medium and configuration.
Suitable Applications
Food & Beverage
The FCH400 is particularly suitable for hygienic flow measurement in food and beverage production. ABB lists the CoriolisMaster FCH430/FCH450 for applications involving dairy products, milk, cream and other hygienic process fluids.
Dairy Processing
Coriolis measurement can provide mass flow, density and temperature information for milk, cream and other dairy-process fluids. The hygienic construction, EHEDG certification and FDA material compliance are especially relevant to these applications.
Pharmaceutical and Hygienic Processing
The FCH400's hygienic design and cleanable wetted materials make it suitable for process installations where contamination control and hygienic equipment design are important.
Batching and Filling
The FCH450 provides FillMass software for filling application control, making this model particularly relevant to hygienic filling processes.
Concentration Measurement
The FCH450 can use DensiMass software for direct concentration measurement. This is useful where density information can be used to determine process concentration.
Process Water and Hygienic Utilities
The FCH400 can be considered for clean process fluids where hygienic construction and accurate multivariable flow measurement are required.
Selection Notes
The FCH400 is a configurable hygienic flowmeter series, so the complete model and order code should be confirmed before quotation.
When requesting a quotation, confirm:
• FCH430 or FCH450
• Process medium
• Required mass-flow range
• Required density accuracy
• Required temperature range
• Nominal pipe size
• Wetted material requirements
• Hygienic requirements
• Process connection
• Required communication protocol
• I/O configuration
• Hazardous-area requirements
• Need for DensiMass concentration measurement
• Need for FillMass filling control
• Need for Enhanced Coriolis Control
For hygienic applications, the process connection and installation arrangement should be checked carefully because the required connection depends on the specific process and cleaning requirements.
For higher accuracy applications, FCH450 offers mass-flow accuracy options down to 0.1% of reading, while FCH430 offers options down to 0.2% of reading.
If concentration measurement is required, FCH450 should be specifically selected because ABB lists DensiMass as an FCH450 software option. Similarly, FillMass is available on FCH450 for filling applications.
