A target flow meter has a target with a broad face attached to the free
end of a rigid stalk. A fixed end of the stalk is attached to a rigid
support secured in the system to be measured with the broad face of the
target disposed transverse to the fluid flow. The support and the stalk
may be made in one piece. Recesses in the support at the junction with
the stalk, one upstream, and one downstream of the flow may reduce the
thickness of the support so that bending of the support in response to
flow forces is concentrated at the recesses. Strain gauges are attached
to the support at the recess areas to measure target movement. The
support is sealed to the fluid chamber with the gauges outside the fluid
chamber. The recesses in the support may be on the fluid side or the
outside of the support.
