Abstract: A flow device including a differential flow plate insertable into a flow path between pipe sections including a flow conduit supporting a flow interrupter and differential pressure taps. The flow conduit including a seamless interface between the flow interrupter and the pressure taps to reduce non-attributable pressure loss between differential pressure taps as well as reduce field installation labor including that of pressure testing the various pressure couplings.

Abstract: A vortex sensor used in a vortex flowmeter that has a single sensing diaphragm parallel to the direction of flow that is sensitive to differential pressures caused by vortices shed by a vortex shedding bar associated with the sensing diaphragm. A beam is attached to the sensing diaphragm and it transfers the deflecting motion of the sensing diaphragm due to differential pressures to a sensor external to the flow passageway. The sensor provides an output indicating motions of the beam caused by the beam pivoting when the sensing diaphragm deflects. The beam preferably is pivoted on a relatively rigid, fluid-tight isolator diaphragm with one end of the beam on the outside of the isolator diaphragm. The sensing diaphragm which is used to measure differential pressure rejects variations in the static pressure, that is, increases and decreases of the static pressure on both sides of the diaphragm, which is a common source of problems with existing vortex flowmeter sensors.

Abstract: A flow device (100) including a differential flow plate (108) insertable into a flow path between pipe sections (58-1, 58-2) including a flow conduit (110) supporting a flow interrupter (112) and differential pressure taps (114, 116). The flow conduit (110) including a seamless interface (154) between the flow interrupter (112) and the pressure taps (114, 116) to reduce non-attributable pressure loss between differential pressure taps (114, 116) as well as reduce field installation labor including that of pressure testing the various pressure couplings.
