Siemens SITRANS FX vortex flowmeters are designed for industrial applications and are optimally suited to the demands of auxiliary supply systems. The proven principle of vortex flowmeters is suitable for measuring liquids, gases and vapours, and is unaffected by conductivity, viscosity, temperature and pressure.
Even the basic version of the vortex flowmeter SITRANS FX330 is equipped with temperature compensation for saturated steam applications. With the optional pressure sensor, the SITRANS FX330 has integrated density compensation for calculation of corrected volume and mass (online density compensation). The density compensation for the calculation of corrected volume and mass is based on NIST standards for gases and IAPWS standards for steam.
Higher measurement accuracy with compact measuring systems.
With the classic installation of a vortex flowmeter, separate pressure and temperature sensors, and a flow calculator, all errors in the measuring chain must be taken into account when determining system accuracy. This can result in a measurement error of ±3 to 5%.
Using a vortex flowmeter with integrated pressure and temperature compensation, such as the SITRANS FX330, allows you not only to lower installation costs but also to increase the accuracy of the measuring point. In this case, the accuracy is ±1.5% of the measured value.
