  • Vortex shedding flow measuring device
    Patent number: 4362061
    Abstract: A vortex-shedding flow-measuring device in which the flowing velocity of the fluid is determined by measuring the frequency of differential changes of two capacitances formed by an electrode structure and the wall of the vortex-generating body. The electrodes are located in a recess formed in one end of the body and extend in the axial direction of the latter symmetrically with respect to the direction of flow of the fluid, whereby to reduce the effects on the measurement signal of vibration of the pipe or similar noise components.
