ABSTRACT:
A device for measuring fluid flow, in particular, but not exclusively, wind and/or water speed and direction. The device includes magnetic measuring means having a core and first and second orthogonal windings arranged over the core, and deflector means adapted to be deflected in use by a fluid flow, the deflector means comprising a deflectable element resiliently connected to further magnetic field means, the deflector means being deflectably mounted with respect to the magnetic measurement means, which provides an output, the magnitude of which output corresponds to the magnitude of deflection of the deflector means, wherein the output is resolvable in two orthogonal axes such that a value for fluid flow direction can be determined.
