The Sitrans F O from Siemens is a differential pressure flow meter suitable for use in non-corrosive and corrosive gases, vapors and liquids. The tool is designed with an operating temperature range from -60 up to +570 °C. This equipment offers a precise outcome even with large bores, high temperature and extreme pressure. The device is a standardized mechanical flow sensor based on DIN EN ISO 5167, used for volume and mass flow measurement.

The instrument is capable of providing differential pressure, which will be converted using differential pressure transmitter SITRANS P delta P into a proportional flow signal. In addition, this differential pressure flow meter can also be used in different areas of applications, such as power stations, petrochemical industry and chemical industry.
