A vortex flow meter has a vortex shedder that spans a diameter or other chord of a fluid-guiding pipe, and protrudes partially externally through two opposed openings in the pipe wall. The vortex shedder includes two spaced-apart mounting pads and an elongate portion spanning therebetween. At least one mounting pad includes a cavity for seating a sensor. One preferred practice of the invention inserts the shedder through the openings into the fluid-guiding pipe such that the elongate section resides within the flowing fluid and produces a stream of space-apart vortices, and the mounting pads protrude at least partially through the openings. The sensor produces electrical signals in response to the induced vortices, and an electronic module receives the electrical signals and calculates the flow velocity of the fluid based on the frequency of the electrical signals.
