Abstract
A body for an acoustic resonance fluid flow speed sensor or an acoustic resonance fluid flow sensor comprising such a body, the body comprising a reflector surface with at least one section that is more hydrophilic than a surrounding section of the reflector surface to promote movement of water from a centre toward an edge of the reflector surface.

A body for an acoustic resonance fluid flow speed sensor comprising a reflector surface with at least one section which extends radially from a centre of the reflector surface to an edge of the reflector surface,
- wherein the at least one section is more hydrophilic than a surrounding section of the reflector surface which extends to an edge of the reflector surface, providing movement of water in a radial direction via the more hydrophilic section from the centre to the edge of the reflector surface.
A method of providing a surface on a body for an acoustic resonance fluid flow speed sensor, the surface being a reflector surface of the sensor and configured to assist drainage of water from the sensor, the method comprising providing at least one section which extends radially from a centre of the reflector surface to an edge of the reflector surface, where the at least one section is more hydrophilic than a surrounding section of the reflector surface providing movement of water in a radial direction via the more hydrophilic section from the centre to the edge of the reflector surface.
