Select and order

The robust frame and housing of the FCS300 guarantee superior resistance to external vibrations, creating an ideal measurement environment with no twisting.


In order to make a complete flowmeter system, the SITRANS FCS300 sensor must be combined with the SITRANS FCT030SITRANS FCT010 or SITRANS FCT070 transmitter.


  • Compactness - enabling smaller and more efficient plant or skid layout
  • Flexibility - available from DN15 to DN150, ensuring a broad application fit
  • Easy installation - with a wide range of standard flange, thread and hygienic connectors
  • High accuracy - ±0.10% or ±0.20% achieved at up to 100 bars and 205 °C
  • “Plug & Play” - with pre-configured sensor cable
  • Digitally reliable - all primary process variables are digitally transferred to the transmitter
  • Global service network - for expert-level support whenever and wherever you need it
