ABSTRACT:
A vortex flow meter for increasing the frequency of vortex shedding to improve the sensitivity of the meter in which the meter body includes a plurality, preferably two, bluff bodies positioned perpendicular to the fluid flow in the meter body. Each such bluff body has an associated sensor downstream of the flow. The spacing between the bluff bodies and between each of the outer bluff bodies and the wall of the meter body is optimized to cause the strongest vortex generation.
