Differentiall pressure measurement is a universal flow measurement for liquids, gases and vapors. Differential pressure flow meter always provide accurate results even with large bores, high temperature and extreme pressure.
Primary differential pressure devices, like SITRANS F O orifice, are standardized mechanical flow sensors according DIN EN ISO 5167 which are used for volume and mass flow measurement. The SITRANS F O orifice are suitable for non-corrosive and corrosive gases, vapors and liquids; permissible operating temperature -60 to +570 °C. The created differential pressue will be converted with the help of a differential pressure transmitter SITRANS P delta P into a proportional flow signal. For calculation of the SITRANS F O orifice to DIN EN ISO 5167 is an completed filled out questionnaire necessary.
Differntial pressure flow meter application examples: Power stations, Petrochemical industry, Chemical industry
