SITRANS FC430 Mass Flow Meter

Building on a strong tradition - now with NTEP approval for custody transfer


Building on a strong tradition of innovative thinking, Siemens has designed the next generation of coriolis flowmeters for excellence in performance, safety and user-friendliness: the SITRANS FC430.

The digitally based SITRANS FC430 flowmeter features market-leading compactness, very high accuracy of 0.1%, low pressure loss, extremely stable zero point and best-in class data update with 100 Hz high-speed signal transfer.

Unique support tools provide direct access to all operational and functional data, certificates and audit trails. The SITRANS FC430 is amongst the first Coriolis flowmeters to offer SIL 3 certification on the system, meeting the highest standards of safety and reliability.

With the SITRANS FC430, process optimization has never been easier - or more innovative.

The  complete flowmeter system SITRANS FC430 can be ordered for standard, hygienic or NAMUR service. All versions can be ordered for CT service, according to OIML R117 (Liquids other than water).

All compact variants can be validated and configured for SIL2 or SIL3 operation as standard. SIL3 operation requires two flowmeters in series and monitored by a SIL rated control system.

The flowmeter is based on the latest developments within digital signal processing technology – engineered for high measuring performance:

  • Fast response to  rapid changes in flow

  • Fast dosing applications

  • High immunity against process noise

  • High turndown ratio of flowrates

  • Suitable for liquid and gas service

  • Easy to install, commission and maintain

FC430 is available as standard with Profibus DP/PA, Modbus RS485 or 4-20 mA analog output with HART 7.2. Additional input/output functions can be freely configured for analog, pulse, frequency, relay or status.

The transmitter comes with a  user configurable graphical display and new SensorFlash® technology, a micro SD card for configuration backup, firmware update and data storage.
