Abstract
A vortex flowmeter employs a differential pressure transducer converting an oscillation in a differential pressure to an alternating electrical signal, which differential pressure transducer is dynamically isolated from a structure including a flow passage in a relationship preventing the transmission of the mechanical vibrations of the structure including the flow passage to the differential pressure transducer, and receives two fluid pressures respectively existing at the two opposite cylindrical sides of a vortex generating bluff body disposed across the flow passage respectively through two small diameter tubings having a low stiffness, wherein the velocity of fluid moving through the flow passage is determined as a function of the frequency of the alternating electrical signal generated by the differential pressure transducer.
