Abstract
An apparatus, according to the invention, detects the relative speed of the apparatus with respect to the fluid into which it extends. The apparatus includes a streamlined body portion having an upper end, a lower end, a front edge, a back edge, and a pair of sides. A conduit extends through the body portion and is exposed to the fluid at an orifice located beneath the fluid line. The other end of the conduit is coupled to a pressure transducer which produces an output proportional to the pressure acting on the orifice and thus proportional to the speed of the apparatus relative to the fluid. This apparatus can be connected to an appropriate speedometer and is particularly useful for measuring the speed of a watercraft to which the apparatus is mounted.
