Abstract: A vortex meter plug for retaining an electronic support tube on a sensor and meter body. The plug secures the sensor in place by means of a plug thread. A dowel pin on the meter body prevents rotation of the sensor from the working position, and one or more set screws are directed downward to bite into the body of the sensor to prevent mutual rotation of the plug and the sensor in order to prevent accidiental release of the sensor when the pipe is under pressure.

Abstract: A one-piece unitary vortex meter body including an outer housing portion having a conduit formed therein with an inner diametrically extending generally wedge-shaped bluff body portion formed in one piece, the housing portion being formed as a relatively thin-walled tubular sleeve with first and second enlarged flange portions at opposite ends thereof, with a pair of first and second diametrically opposed and aligned integrally formed reinforcing ribs extending radially outwardly from the outer surface of the tubular sleeve and extending between the inner facing surfaces of the flange portions. On a perpendicular diameter, there is provided a thicker radially extending reinforcing rib and a relatively large diameter columnar protrusion extending radially beyond the periphery of the flange portions, the protrusion and bluff body having formed therein a receptacle for receiving therein a sensor assembly.

Abstract: A vortex meter sensor including an outer beam assembly having a receptacle formed therein for receiving therein an inner beam assembly. The outer beam assembly includes a sensor body with an integrally attached axially aligned outer cantilever beam member. The cantilever beam member has an upper tubular portion and a lower vane-shaped portion. The inner beam member is a unitary member with a flange portion for securing within a complementary portion of the receptacle, with a strain gauge beam member depending from the flange portion along with an axially aligned rod-shaped inner beam member. The inner beam member is configured for being received in spaced relation within the tubular portion of the outer beam member with the lowermost end of the inner beam member being secured to the lowermost end of the tubular portion.
