Abstract
The invention concerns a Karman's vortex flow meter including dampening members for absorbing vibrations. A stopper is provided to permit limited movement between an amplifier casing and a supporting stand containing a flow detector. The stopper is coupled to one of the supporting stand and the casing and extends into a hole in the other of the supporting stand and the casing. The flow meter includes an elastic member positioned in the hole between the stopper and the other of the supporting stand and the casing so that the stopper and the other of the supporting stand and the casing are out of direct contact. The elastic member absorbs vibrations and prevents direct contact of the components to ensure accurate flow measurement.
