Zusammenfassung:A flow meter 10 comprises: a flow target 14 arranged to be disposed in a fluid flow path in a conduit 12; a beam 16 coupled to the flow target 14 and arranged to extend outside of the conduit 12; a sensor 20 and a resilient arrangement 18 where a resiliently deformable member is coupled to and extends into the conduit 12, the beam 16 being partially disposed within the hollow member. The hollow member bends is response to a fluid flow acting on the flow target 14. The sensor 20 has a moveable sensor part 62 (see figure 7) coupled to the beam at a position which in use is outside of the conduit 12 and a static sensor part 64 wherein displacement of the moveable sensor part 62 with respect to the static sensor part 64 generates a signal. In use, fluid flow acting on the flow target 14 causes displacement of the moveable sensor part 62, thereby generating a signal which is representative of the fluid flow rate. The sensor 20 can be an inductive sensor.
