Siemens SITRANS FS230 Transmitter is versatile and can accommodate pipe diameters ranging from DN10 to DN10,000. When dealing with applications in hazardous areas, the external electronics module, SITRANS FS DSL, comes into play.


  • Easy installation; no need to cut pipe or stop flow
  • Minimal maintenance; external sensors do not require periodic cleaning
  • No moving parts to foul or wear
  • No pressure drop or energy loss
  • Wide turn-down ratio
  • Single or dual path with internal DSL, up to four paths with external DSL option


SITRANS FS230 standard functions are suitable for a wide variety of liquid applications, including the following:

  • Water industry (Raw water, Potable water, Chemicals)
  • Wastewater industry (Raw sewage, Effluent, Sludges, Mixed liquor, Chemicals)
  • HVAC industry (Condensers, Hot and cold water systems)
  • Power industry (Nuclear, Fossil, Hydroelectric)
  • Processing industry (Process control, Batching, Rate indication, volumetrics, and mass measurement)

SITRANS FS230 hydrocarbon functions are ideal for applications carrying crude oil, refined petroleum, or liquefied gas.
