Explore: Differential Pressure

pressure sensors are really differential pressure sensors; for example a gauge pressure sensor is merely a differential pressure sensor in which one side

cause the pressure inside the Venturi to change. This principle can be used in metrology for gauges calibrated for differential pressures. This type

the differential pressure across the orifice's pressure tappings and applying an appropriate constant. Orifice plates are also used to reduce pressure or

used for pressure head and hydraulic head. In a venturi flow meter, the differential pressure head can be used to calculate the differential velocity
