Abstract
A wind meter comprising a plurality of micro-electro-mechanical (MEM) differential pressure sensors positioned in a lobed housing, with an even number of circumferential ports arranged in an equally-spaced, circular pattern at the distal ends of the lobes of the housing, with tubes leading inward from the ports to the MEM sensors. The MEM sensors and other control system electronics are contained in the housing and are fully enclosed therein. The lobed housing structure does not impede or influence the movement of the wind as it passes and yet serves to prevent the ingress of moisture into the housing, thereby preventing fouling of the sensors. The tubular structures include an internal coating of hydrophobic material and are oriented at a slight angle from the horizontal in order to accomplish this protection. The openings at the ends of the tubular structures are positioned outside the fluid boundary layer.
