Abstract

PURPOSE:To obtain a measuring device for speed and rate of flow by Karman vortex streets of less noise by providing stress detectors in the position where the bending moments in a force receiving body are zero, and the position of the same code as an increase in the bending moments by an additive. CONSTITUTION:A force receiving body 2 having a flange part 21 and a recess 22 is supported to a pipeline 1 by a screw 3 through a cylindrical nozzle provided at a right angle to the pipeline 1. A stress detecting part 4b disposed in a position where the alternating bending moments based on Karman vortex streets are zero and a stress detecting part 4a disposed in a position of the conditions of the same code as an increment of the bending moments by an additive based on disturbing force are sealed in the recess 22 of the body 2 by being insulated from the body 2 by an insulating material 5. If the outputs of the parts 4a, 4b constituted in this way are processed differentially, the noise components of the inphase detected by the parts 4a, 4b are canceled and therefore the speed and rate of flow are measured with good S/N.
