Abstract
A vortex flowmeter employs a differential pressure transducer converting oscillation in a differential pressure to an alternating electrical signal, wherein the differential pressure transducer comprises a pair of pressure compartments (10 and 11) respectively receiving two fluctuating fluid pressures respectively existing at two fluid regions located on the two opposite sides (8 and 9) of a vortex generator (3) respectively through a pair of tubings (13 and 14, 43 and 44, or 61 and 62) or through a pair of holes (69 and 70, or 72 and 73) embedded within the wall of the flow passage.
