SIEMENS SITRANS FX330 Vortex Flowmeter
Siemens SITRANS FX Vortex flowmeter are designed for use in industrial applications and optimally suited to the demands in auxiliary supply systems. The proven principle of vortex flowmeters is suitable for measure ment of liquids, gases and vapors unaffected by conductivity, viscos ity, 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 com pensation for calculation of corrected volume and mass is based on the standards of NIST for gases and IAPWS for steam.
Higher measuring accuracy with the use of compact measuring systems.
With the classic installation of a vortex flowmeter and separate pres sure and temperature sensor as well as flow calculator, all errors occurring in the measuring chain must be taken into account when determining system accuracy. This can result in a measuring error between ± 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 increase the measuring accuracy of the measuring point. In this case the accuracy is ± 1.5 % of the measured value.
