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.
