Siemens SITRANS FX vortex flowmeters provide accurate volumetric and mass flow measurement of steam, gases and liquids as an all-in one solution and include integrated pressure and temperature compensation. The FX300 is a compact vortex flowmeter in a single or dual transmitter version, and is suitable for measuring industrial steam, gases, as well as conductive and non-conductive liquids. E.g. steam (saturated steam, superheated steam), industrial gases (compressed air, nitrogen, liquefied gases, flue gases), and conductive and non-conductive liquids (demineralized water, boiler feed water, solvents, heat transfer oil).

Siemens SITRANS F X vortex flowmeters detect the frequency at which alternating vortices are shed from a bluff body inserted into the flow stream in order to measure flow rate. This principle of measurement
is known as Von Karman's vortex street principle: alternating vortices form behind an object in a stream. The frequency of the alternating vortices is proportional to the flow rate. The passage of a vortex causes a slight stress on a pick-up placed downstream of the bluff body. The stress is picked up and counted as pressure surges by a dual Piezo crystal placed inside the wing.

The main applications of the SITRANS vortex flowmeters can be found in the following


  • All devices have 2-wire technology and HART communication
  • Temperature compensation for saturated steam is a standard feature
  • Pressure, temperature and flow can be read at a single point.No additional installation of pressure and temperature sensors
  • Direct measurement of energy or energy consumption
  • Integrated temperature and pressure measurement enabling direct compensation of density
  • Optimum process reliability thanks to Intelligent Signal Processing (ISP) - stable readings, free of external perturbations
  • Fully welded stainless steel construction with high corrosion, pressure and temperature resistance
  • Maintenance-free sensor design
  • Ready to use due to plug & play feature. No additional cabling work
  • Minimal pressure drop
  • All units parameterized prior to delivery
  • Pressure and temperature compensation for fluctuating volume flows
  • Measurement of consumption in compressed air systems
  • No risk of deposits or damage (sensor in the turbulent area
