Description
Differential pressure measurement is a universal flow measurement for liquids, gases, and vapors. Differential pressure flowmeter always provides 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 to DIN EN ISO 5167 which are used for volume and mass flow measurement. The SITRANS F O orifice is suitable for non-corrosive and corrosive gases, vapors and liquids; permissible operating temperature -60 to +570 °C. The created differential pressure 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 a completed filled out questionnaire necessary.
Differntial pressure flow meter application examples: Power stations, Petrochemical industry, Chemical industry
