Abstract
A Karman's vortex flow meter eliminates the problem of external vibration resonating an amplifier casing to lower measurement accuracy of a vortex detecting section. In the flow meter, O-rings fit in two annular grooves formed on an outer surface of a supporting stand hollow cylinder. A casing fits onto the hollow cylinder of the supporting stand with the two O-rings being placed therebetween. A pair of blind holes or recesses formed in the hollow cylinder diametrically oppose one another and are located between the two O-rings. Bolts inserted into the recesses with gaps spaced around their end portions serve as stoppers by limiting axial movement of the casing with respect to the hollow cylinder.
