Siemens Energy & Automation, Inc. has announced the U.S. introduction of the Sitrans FX300 vortex flowmeter series, which is equipped with a temperature sensor and an optional pressure sensor. Through the combination of these sensors into one unit, the vortex principle is used to measure the temperature, pressure and flow of steam, gases and liquids. The “All-in-one Solution” series is suitable for a range of applications in the chemical, pharmaceutical, food and beverage, oil and gas, energy generation and district heating industries.

The Sitrans FX300 two-wire flowmeter with Hart communication is designed for applications requiring reliable flow measurement independent of dynamic pressure, temperature, viscosity and density variations. These applications include the measurement of steam and saturated steam, monitoring of steam boilers, control of compressor outputs, consumption measurement in compressed air systems, measurement of industrial gases, burner consumption measurement, and SIP and CIP processes in the food and beverage industry and pharmaceutical industry.

The flowmeters are characterized by high accuracy and reliability. The sensor is fully welded and does not require wear-prone internal gaskets. The operating temperature range is from minus 40 to plus 464 degrees Fahrenheit. In the case of steam and gas with flow rates of 2 to 80 meters/second, the accuracy is 1.0 percent, and in the case of liquids flowing at rates between 0.4 and 10 meters/second, it is 0.75 percent. The nominal internal diameter range is DN15 to DN300 (0.5 inches to 12 inches).

The Sitrans FX vortex flowmeter works on the vortex measuring principle. This involves detecting the frequency at which alternating vortices are shed from a buff body hit by the flowing medium. These vortices create a force on a sensor wing that moves in proportion to the volume of flow. This sensor has a dual piezoelectric crystal mounted in the wing that detects the oscillations precisely and transmits this information to the FX electronics for conversion to the actual flow rate in the pipeline.
