Orifice Flow Measurement

 Zoom

The SITRANS F O orifice flowmeters are suitable for non-corrosive and corrosive gases, vapors and liquids; permissible operating temperature -60 to +570 °C. The electronics is easy to parameterize anew if process data should change. Adaptation is by recalculation and reparameterization of the transmitter or, in the case of the orifice plate with annular chamber, by using a new orifice disk.


Orifice flowmeter features

  • Orifice flowmeters are very robust and can be used in a wide range of nominal diameters
  • Suitable for wide ranges of temperature and pressure
  • No calibration required as the process is standardized
  • The electronics required in addition can be used over a long distance from the measuring location
  • The differential pressure method is well known and has a large installed base
