Applications
The FSS450 is suitable for steam distribution and energy monitoring, natural gas measurement, petrochemical processing, demineralized water measurement, and compatible industrial liquid applications. Its integrated calculation capabilities are particularly useful when mass flow, gas-condition correction, or steam energy measurement is required.
Why Choose ABB SwirlMaster FSS450?
The FSS450 combines flow measurement with advanced calculation functions in one instrument, potentially reducing the need for a separate flow computer. Its flexible communication options and external sensor inputs make it suitable for demanding industrial automation and process monitoring systems.
Frequently Asked Questions
1. What is the ABB SwirlMaster FSS450 used for?
The FSS450 measures gases, liquids, and steam. It also supports advanced mass flow, standard volume flow, and energy calculation applications.
2. What is the difference between the ABB FSS430 and FSS450?
The FSS450 adds an analog input and integrated flow computer functionality for advanced calculations, including gas-condition correction and steam energy measurement. The FSS430 is primarily designed for standard flow measurement applications.
3. Can the FSS450 measure steam mass flow?
Yes. With suitable temperature measurement and configuration, it supports saturated steam mass-flow calculations. It can also support steam energy calculations when the required process inputs are available.
4. What is the accuracy of the FSS450?
ABB specifies an accuracy of ±0.5% of rate for liquids, gases, and steam.
5. What pipe sizes are available?
The FSS450 is available in flanged designs from DN 15 to DN 400 (½ to 16 inches).
6. What communication protocols does the FSS450 support?
Depending on the selected configuration, available options include 4–20 mA/HART 7, Modbus RTU-RS485, and Ethernet-APL-based Modbus TCP and PROFINET.
7. Can external pressure and temperature sensors be connected?
Yes. The additional analog input can accept suitable external process signals, such as pressure or temperature, for supported flow calculations. Confirm the required input type and configuration before ordering.
8. How can I request a quotation for the ABB FSS450?
Provide the required flow range, process medium, pressure, temperature, pipe size, communication requirements, and whether mass flow or energy measurement is needed. These details help determine the appropriate configuration and quotation.
