Title: Target flow meters with immersed strain gauges

Abstract: A target flow meter has a target with a broad face attached to the free end of an elastic stalk. The stalk has at least a portion with an oblong cross section. A fixed end of the stalk is attached to a rigid support secured in the system to be measured with the broad face disposed transverse to the fluid flow. Strain gauges are affixed to the longer sides of the oblong portion. A temperature sensor may also be affixed there. The strain gauges are immersed in the fluid to be measured. Wires to the gauges and sensor pass through a fixed seal to the outside. They may be protected from the fluid by an impervious coating. By applying the strain gauges within the fluid, the system may be reduced in size, achieve greater sensitivity, and better temperature compensation.
