Overview

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 measurement of liquids, gases and vapors unaffected by conductivity,viscosity, temperature and pressure.

Benefits

* Integrated pressure and temperature compensation
* Temperature compensation for saturated steam included as standard
* High measuring accuracy
* Maintenance-free sensor
* Non-wearing, fully welded stainless steel construction with high resistance to corrosion, pressure and temperature
* SIL2 certified according to IEC 61508 Edition 2
* Use in hazardous areas
* Integrated reduction of nominal diameter for space-saving and economic installation and large measuring ranges
* Redundant data management: Easy exchange of electronics without loss of calibration and configuration data
* FAD (Free Air Delivery) functionality
* Gross and net heat calculation to support advanced energy management
* Remote version with cable length up to 50 m (164 ft)
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 calculation of corrected volume and mass is based on the standards of NIST for gases and IAPWS for steam.

Application

* Measurement of saturated steam and superheated steam
* Steam boiler monitoring
* Heat metering of steam and hot water
* Measurement of consumption of industrial gases
* Measurement of consumption in compressed air systems
* Monitoring of compressor output
* Evaluation of Free Air Delivery (FAD)
* SIP and CIP processes in the food, beverage and pharmaceutical industries
* Measuring of conductive and non-conductive liquids
* Safety-related measurement in SIL applications (SIL2)

Function

Vortex flowmeters are used to measure the flow of gases, vapors and liquids in completely filled pipes. The measuring principle is based on the principle of the Karman vortex street. Inside the measuring sensor vortices are shed from a bluff body and are detected by a sensor located behind. The frequency f of the vortex shedding is proportional to the flow velocity v.The nondimensional Strouhal number S describes the relationshipbetween vortex frequency f, width b of the bluff body and the mean flow velocity v:f = (S · v) / b
The vortex frequency is recorded at the sensor and evaluated at the converter.
