Abstract
A force sensing and transmitting mechanism for a vortex flowmeter which includes a force sensing beam at one end, a force transmitting beam at the other end, and a thin plate joining the two together. The force sensing beam is disposed in the passageway flow path adjacent a vortex generator. The force transmitting beam projects outside of the passageway. The adjoining plate includes a central portion fixed to the sensor beam and the transmitting beam and with outer plate edges fixed to the housing to provide a first pivot point. A second pivot point is provided at the opposite end of the force transmitting beam and transducer means are mounted at the second pivot point to detect rotational deflection of the force transmitting beam corresponding to vortex induced pressure differentials. The second pivot point includes a rocker member rigidly attached to the force transmitting beam and having a V-shaped groove in engaging contact mating with V-shaped projections fixed to the housing. Rotational deflection of the force transmitting beam tends to rockingly deflect the rocker member on the V-shaped projections corresponding to vortex induced pressure differentials.
