Abstract:
A vortex flowmeter for determining a flow velocity of a fluid flowing in a pipe, the vortex flowmeter comprising:a flow-obstruction element for inducing a stream of vortices in the fluid, the flow-obstruction element including a sensor element for determining the flow velocity of the fluid based on the vortices, and a plurality of diaphragms disposed on opposed sides of the flow-obstruction element to transmit at least one pressure fluctuation associated with the vortices to the sensor element, and at least one elate disposed at opposite radial ends of the flow-obstruction element for directing fluid flow, the opposite radial ends being disposed on an axis perpendicular to a direction of fluid flow, a first flange sub-assembly having a first flange for removably and replaceably disposing the flow-obstruction element through an opening in the pipe, the flow-obstruction element sized and positioned to partially span the pipe when disposed therein, and a second flange sub-assembly having a second flange for coupling to the first flange for mounting the first flange sub-assembly to the pipe.
